Amare Stoudemire, Lamar Odom's "Lucky Game"
and What it Means to be a Superstar

From 20 Second Timeout

"... After Lamar Odom had 19 points and 19 rebounds as his L.A. Lakers defeated the Phoenix Suns 128-107 in game one of the 2010 Western Conference Finals, the Suns' Amare Stoudemire dismissed Odom's effort as a "lucky game." ..."

"... "Lucky" literally means "occurring by chance." How unusual was it for Odom to tally 19 and 19 during a 2010 game? ..."

"... Stoudemire's comment may have been ungracious and it may have been an unwise thing to say in the midst of a playoff series but - from a literal standpoint - it was quite true: a 19-19 game by Odom is truly something that happened "by chance." ... "

"... However, in a game of skill nothing really happens purely "by chance." The skill set based reason that Odom had a wide open path to the hoop for layups and rebounds is that the Suns had to double team Kobe Bryant--who still scored 40 points on 13-23 field goal shooting--and then rotate a defender to Pau Gasol, who took advantage of the Suns' scrambling defense to notch 21 points on 10-13 field goal shooting. ..."

"... Most of the published comparisons of James' supporting cast with Bryant's supporting cast have been nonsense. Yes, Bryant had the benefit of playing alongside one of the NBA's 15 best players, All-NBA Third Teamer Pau Gasol--but during the 2010 playoffs Bryant also played alongside a one-legged center, a small forward who never quite learned the team's offensive system, a point guard who was older and slower than the starting point guards on the other elite teams, a sixth man who was terribly inconsistent and a bench that was so unreliable that earlier in the season Coach Phil Jackson said that their performances made him feel like vomiting. James' supporting cast was not perfect but it included three players who have made the All-Star team as recently as 2008 plus a fourth player who is a two-time All-Star; the Cavs' remarkable depth and balance enabled them to play "big" or "small" and to overcome injuries, trades and other disruptions en route to posting the league's best regular season record for the second year in a row. ..."

Basketball Statistics Analysis Referred Concepts:
How Much Turnovers Stats Actually Worth ?

Looking at turnovers stats and how much they are actually worth. Points off turnovers are often strongly correlated with the number of turnovers by the opposition.

Go understand, the team that turns the ball over more will often lose.
Is it really the points off the turnovers, or is it the lost opportunities to score by the team that is making more mistakes ?

The Points Off Turnovers analysis conducts us to the "floor percentage", a method popularized by Dean Oliver in his book "Basketball on Paper", which measures offensive efficiency.

Photograph: The No-look Pass

Basically it's baskets and offensive rebounds as a ratio of attempted baskets plus turnovers (see the Discussions about Stats at the eBA Forums).

In other words, when there is a chance to turn the ball over (TOs and FGA), how often does your team profit from it? "Profit" in this two means: to make a basket or get another chance with a rebound.

Comparing sports, points off turnovers means a lot in football, but not so much in basketball because only half of all turnovers are steals which potentially lead to fast breaks the other way.

The other half give the ball to the other team out of bounds, which isn't always much of this POT advantage.

Basketball Registering Stats Referred Questions:
Restrictions Governing Jump Balls ~ Rule & Statistics

"... On a jump ball, when can a player touch the ball ?

In case of violation at the first jump ball: is a personal turnover or a team-player one ?

What is the correct rule and, specially, the statistical
registration ? ..."

Rule's Fundamental=
These are the restrictions governing jump balls:

a. Each jumper must have at least one foot on or inside that half of the jumping circle which is farthest from his own basket in NBA or the opponent basket in FIBA. Each jumper must have both feet with-in the restraining circle.

b. The ball must be tapped by one or both of the players participating in the jump ball after it reaches its highest point. If the ball falls to the floor without being tapped by at least one of the jumpers, the official off the ball shall whistle the ball dead and signal another toss.

c. Neither jumper may tap the tossed ball before it reaches its highest point.

d. Neither jumper may leave his half of the jumping circle until the ball has been tapped.

e. Neither jumper may catch the tossed or tapped ball until it touches one of the eight non-jumpers, the floor, the basket or the backboard.

f. Neither jumper is permitted to tap the ball more than twice on any jump ball.

g. The eight non-jumpers will remain outside the restraining circle until the ball has been tapped. Teammates may not occupy adjacent positions around the restraining circle if an opponent desires one of the positions. No player may position himself immediately behind an opponent on the restraining circle.

Penalty for c., d., e., f., g.: the ball is awarded out-of-bounds to the opponent

eBA Basketball Statistics Registration=
In case of violation at the first jump ball is a team-player unforced turnover.

Sunday's Reflexions on Basketball Statistics:
Encourage youth players to keep studying

This Sunday morning, the reflexions are about youth basketball... I think that the best youth coach is who encourage players to keep studying, by showing them, for example, that even if they are the best player in their high school, their chances of getting in the first level (NBA, Euroleague....) are still less than 1%.

Therefore we need to think a little... How many players are in the NBA ? And how many players join the NBA each year ?

Photograph: Fernando Medina from Orlando Magic

Let make numbers:
In the NBA there is 29 NBA teams with 15 players per team and a total of 435 per year.
We have 1,200 colleges teams with 10-15 players per team and a total of 18,000 per year: the chance stands on 41-1.
In the 25,000 high schools team with 10-15 players per team and a total of 375,000 per year: the chance, 862-1.

Stay in school and study hard is the message, because the numbers are not good for any player to make it to the NBA. Ana take in account that this numbers are theoretically based on every NBA place being open... not likely in any given year. Let say that each NBA team has two new players per year, then the chance for a high school player go up to 6250-1. Is it clear ? Thoughts ?

Effects of consecutive basketball games on the game-related statistics
that discriminate winner and losing teams

From The Free Library
By Sergio Jose Ibañez et al.
Download source here: ' Effects of consecutive basketball games on the game-related statistics that discriminate winner and losing teams ' by Sergio Jose Ibañez et al.

"... Performance analysis in ball team sports such as basketball is a fundamental tool for coaches, allowing them to have valid and reliable information concerning their team and opponents.

Generally, coaches and researchers use this information to identify the most valuable players and the importance of certain specific roles, to assess the impact of rule changes, to investigate the home advantage or to evaluate the participation in the game by starting and reserve players, with the goal of determining how each player contributes to team performance. ..."

"... The players and the teams' performances can decrease after several consecutive games. For example, ...... decreases in several physical capacities (speed, agility, and jump power) during 3-day tournaments. This may be due to accumulated fatigue from successive games, which affects decisionmaking and skill execution.

This way, ...... they highlighted the importance of using adequate conditioning and recovery training programs. In fact, monitoring fatigue is important, particularly in younger players who always want to perform optimally in all the stages of the game, which may have the consequence of an excessive physical exertion after various consecutive games. ..."

"... The descriptive results and univariate differences from both seasons of the under-20 league for each game played are presented in Table 1. Winning teams in this competition had better values in all game-related statistics, with the exception of 3 point field goals and free throws missed and turnovers (p = 0.05).

The main effect of game number was only identified in turnovers, with a statistical significant decrease between the second and third game. No interaction was found in the analysed variables (Table 1). ... "

"... The remaining results seem to confirm previous studies by identifying the same game-related statistics that discriminate winning and losing teams. The contribution of defensive rebounds to winning basketball games is already widely documented.

This statistic represents the "teams' ability to recover the ball after opponent's missed shots and a successful defensive rebounding team probably has more opportunities to shoot, score points and win the game".

Indirectly, high level performances are associated with
i) game rhythm, because more defensive rebounds implies more fast-break ball possessions;
ii) players somatic characteristics, taller and stronger players secure more rebounds;
iii) technical and tactical preparation, pivoting, blocking, anticipation, securing and pulling the ball away, and,
iv) muscular fitness, particularly in stretch-shortening-cycle jumping performances. ..."

"... Key points:

Overall team performances along the three consecutive games were very similar, not confirming an accumulated fatigue effect.

The results from the three-point field goals in the third game suggested that winning teams were able to shoot better from longer distances and this could be the result of exhibiting higher conditioning status and/or the losing teams' exhibiting low conditioning in defense. ..."

Basketball Statistics Analysis Referred Concepts:
About the Assist to a Dunk or to a Three-pointer

Talking about dunks & stats, I value passing as one of the most important skills in basketball. I was wondering, discussing about the eBA Basketball Statistics Analysis System, about any good passing statistics analysis rules based in my last message about the rebounds qualification in disputed, undisputed, by zones, number of players, etc.

For example, is the same a close assist to a dunk than an assist for an open three pointer ? How we can get an idea of how good our players are at passing the ball which leads to a score ?

Photograph: There He Is

An opening statement to begin, when working with databases which are based on how often players pass the ball, you must take into account that this data doesn't qualify how good the passes are.

According to our database the percent of passes that ended up in assists oscillates between ranges of 16.50% and 17.50% from the total number of passes, being the big men at the head of the list, what make me doubt about the value of this data.

In the eBA Basketball Statistics Creative Analysis System we calculate the player's number of passes based on his assists and not vice versa. We have not players with higher percentages - than the referred above - of assists per pass in our archives, and the differences are simply a factor of his team's game pace.

Meanwhile I prepare the second part of this message, we can look at this 'Pass Rating' applied by our eBA Basketball Statistics Creative Analysis System, which recompense the passer of a close assist and a dunk assist, because I think that passes were the principal supply to the basket:

Pass Rating = ( 3pt AST + 2pt Jump AST + ( 2*Close AST )+ ( 4*Dunk AST ) - ( 2* Pass T/O ) ) / ( minutes played / 40 or 48 )

Basketball Registering Stats Referred Questions:
No Double Dribble until a Set is Ended ~ Rule & Statistics

"... A player has possession of the ball with both hands:
- he stoops down and puts the ball on the floor with both hands still on the ball.
- he stands up again with the ball still in his hands and stoops down again and put the ball back on the floor with his both hands still on the ball, is this a double dribble call? ?

What is the correct rule and, specially, the statistical registration ? ..."

Rule's Fundamental=
There are a couple of meanings in this situation: the first depends on whether or not the player started to dribble. The described action, if it is his first movement with the ball would not be a double dribble.

The motive for this ratification is because a dribble is done when "a player in ball control, who throws or taps the ball into the air or to the floor". At no moment of the described action the player "throws or taps the ball into the air or to the floor".

As a result of it is that the player never had his first dribble, so having a second would be impossible.

Photograph: Newsleader.com

Game's Rule=
In the action described above the player would still be breaking the rules, and this violation would be "Traveling".

This would be the second meaning coming from the application of the double dribble rule, that would be if the described action was made with only one hand.

eBA Basketball Statistics Registration=
Unforced Turnover.

Although in the case in which a player get a pass from another player or catches a rebound, he crouch through the floor, put the ball on it with his both hands still on the ball, then stand up and crouches again putting back the ball on the floor again with his both hands still on the ball while its on the floor, in order to protect the ball from his opponent: this is not double dribble because the ball never left the player's hands. It's impossible to get a double dribble call until one set of dribbling was ended.

Sunday's Reflexions on Basketball Statistics:
Stealing the Ball Requires Concentration

"... Stealing the ball requires concentration, good anticipation, speed and fast reflexes and good hustle, all common traits of a good defender.

However, like blocked shots, steals aren't always a perfect gauge of a player's defensive abilities. An unsuccessful steal can result in the defender being out of position and unable to recover in time. Therefore, a steal is a gamble. And a steal usually leads to a fast break, the most exciting play in the sport.

If an offensive player loses possession of the basketball due to a steal, he/she is recorded as making a turnover and the defender is recorded with a steal, forced or unforced depending upon the play development.

Photograph: from Fingerroll

The eBA Basketball Statistics Analysis System registers, in addition to the traditional stats, the points made from the forced and unforced steals done during the game. This number is not always similar, as people usually thinks, to the opponent's points off turnovers. ..."

Currently at the eBA Forums we are discussing the following question: What is an unsuccessful steal worth ? Evidently a successful steal is of great importance, not only because the possible points allowed by the stolen possession, but also to the augment in offensive efficiency arising after a steal.

But... what is an unsuccessful steal worth ? And more accurately, how do we determine whether a steal attempt is sufficiently valuable to justify the implicit risks ?

"... How do employers decide the salary payout to their employees every year? In a sales and consulting firm the salary can be based on the number sales or clients serviced.

How do the National Basketball Association (NBA) team owners decide the players’ salaries?

The general consensus of basketball fanatics is that the wages are based on points scored..."

"... Throughout this article I will frequently refer to the term cost driver, which is an independent variable that drivers or affects the dependent variable of salary.

Basically, the cost driver is on the x-axis and the salary will be on the y-axis.

After performing the regression, there are two crucial measures that I will observe closely... "

"... I decided to conduct a multiple regression on the points, assists, rebounds, games played, and salary as a final attempt to determine the validity and reliability of the data.

"... To conclude, one cannot determine with absolute certainty that an NBA player’s salary based on statistic analysis of measurable statistics such as points scored, assists, rebounds, and games played.

I was able to learn that a player’s salary is not solely based on the measurable performance stats.

Through my statistical analysis or investigation, I state that no player’s salary can be reasonably determined on the basis of performance on the court. ..."

Basketball Statistics Analysis Referred Concepts:
About the Individual Rebounding Percentage

The Individual Rebounding Percentage (Reb%) is similar to the team Reb% formula, except that we account for playing time.

Since all missed shots must be rebounded by the offense or defense (or at least they're credited to one of the teams), we can measure how effective a player is at rebounding by comparing his rebound total to the number of shots missed while he's on the court.

The eBA Basketball Statistics Analysis System multiplies the number of rebounds in the game times the percentage of the game that the player was on the court to arrive at an estimate of how many missed shots were available to a player to rebound.

The percentage of those available rebounds that he actually catches is his rebound percentage.

Photograph: Sports Sina

Off% = Offensive Rebounds / ( Playing Time *
( Team’s Offensive Rebounds + Opponent’s Defensive Rebounds ))

Def% = Defensive Rebounds / ( Playing Time *
( Team’s Defensive Rebounds + Opponent’s Offensive Rebounds ))

Reb% = Total Rebounds / ( Playing Time *
( Team’s Total Rebounds + Opponent’s Total Rebounds ))

Basketball Registering Stats Referred Questions:
Technical Foul in an Inbounds Situation ~ Rule & Statistics

"... A player is called for a technical foul for committing a foul while the ball was being inbounded from the sideline. Are all fouls committed during a dead ball situation now technical foul ? Are considered TO by the Stats-Men ? ?

What is the correct rule and, specially, the statistical
register ? ..."

Rule's Fundamental=
In all guarding situations, a player is entitled to any spot on the court he desires, provided he gets to that spot first without contact with an opponent.

In all guarding situations during a live ball, a player is entitled to any spot on the court he desires, provided that he gets to the spot first without contact with an opponent.

In all guarding situations during a dead ball, the defensive player(s) must be allowed to take a position between his man and the basket.

Photograph: Paul Sancya for Sulekha.com

Game's Rule=
Contact while the ball is dead should be ignored unless it’s intentional or flagrant. A contact foul during a dead ball, is a technical foul and an Unforced Turnover for the eBA-stats.

After the ball has been dead, it is put into play by a jump ball, throw-in, or a free throw attempt. The game clock does not start until the ball is legally touched on the court by a player. However, we wish to penalize any floor violation or personal foul which may occur.

Therefore, the ball is live when it is placed at the disposal of the thrower-in or free throw shooter, or is tossed on a jump ball.

eBA Basketball Statistics Registration=
That last remark is solely for the purpose of not having to assess a technical foul if illegal contact occurs, in which case the eBA Basketball Statistics Analysis System register the foul and charges with an Unforced Turnover to the player who made the foul.

See in our forum the 'technical fouls' topics and the exposition "Basketball Free Throws Statistical Analysis" at eBA ONLINE.

All the terms in this answer are explained widely at The Global Basketball Encyclopedia and in eBA ONLINE.

Basketball Books Review: This week eBA DVICE !

The Assist: Hoops, Hope, and the Game of Their Lives
By: Neil Swidey

In this engaging book about Boston's Charlestown High School basketball team, Swidey, a staff writer for the Boston Globe Magazine, explains that being part of the Charlestown program was no guarantee that a kid would become a success.... But dropping out of the program dramatically increased the odds that he wouldn't.

Head coach Jack O'Brien benefited from the team aside from its gaudy won-loss record. Unmarried and with a shattered family history, O'Brien found that the rigid team structure... offered the trappings of home. Like a concerned parent, O'Brien worked year-round to keep his kids away from the overwhelming daily wave of crime and bad influences and into the security of a college-educated future.

Swidey masterfully shows over the course of two seasons the struggle O'Brien and his players face in maintaining success on and off the court. The coach observes the lives of his two star players, Ridley Johnson and Jason Hood White, go in very different directions after they land out-of-state college scholarships.

Swidey expertly examines the slippery slope of Charlestown's success, tying it into Boston's disastrous busing scandal and an underwhelming legal system that perpetuates crime, while he builds narrative momentum and details his subjects with the touch of a skilled novelist.

This is a prodigiously reported, compulsively readable book that readers (sport fans or not) will savor.

Sunday's Reflexions on Basketball Statistics:
15,97% of the Basketball Possessions End in TO

How we perform the analysis of one team´s turnovers in relation with other team, let say the next opponent at the next game ?

If a team averages 15 turnovers a game, and the next opponent is a team that forces 15 turnovers a game, is it possible to assume that there will be 15 turnovers for that game ?

Or... we must take the league average as the basic unit to analyze this data: if the league average for turnovers is 16.4 that´s means that each team turnover rate is 109,33% compared to the league...

Photograph: Julian H. Gonzalez from Daily Me

During the eBA Basketball Statistics Registration Clinics I expressed my opinion that 'exclusive ratings' and 'scientific formulas' employ only a lacking minimum of the significantly important statistics: turnovers per possession and Defensive turnovers per possession; games won and games lost; etc.

But all other information as playoff game vs meaningless garbage time, recent injuries, possible matchup advantages, etc. (see the thread about eBA System Non Standard Statistics ) are disregarded.

Homecourt advantage is usually disregarded too, (see this thread about Home & Road Stats: differences ) meanwhile the Game Analysis & Scouting takes in account every one of this categories, and much more.

You can reach to the answer to your question by a different way: express the team's turnover proclivity in terms of the proportion of possessions that end in turnover - according to the eBA Basketball Statistics Analysis System Archives: around the 15,97% of the possessions end in turnover.

Running a One Man Fast Break: Pro Basketball's Greatest Rebounding Guards

From 20 Second Timeout
By David Friedman
Download source here: ' Running a One Man Fast Break: Pro Basketball's Greatest Rebounding Guards ' by David Friedman

"... Kidd is one of 11 guards in pro basketball history who averaged at least 6 rpg in five or more seasons (minimum of 60 games played or 350 rebounds each year).

Bob Cousy was the first guard to do this, averaging a career-high 6.9 rpg as a Boston Celtics' rookie in 1950-51, and following that with 6-plus rpg averages in four of the next five years.

During this period the fast breaking Celtics were consistently the leading scoring team in the league, but their lack of defensive presence in the paint always proved to be fatal in the playoffs. ..."

"... Richie Guerin averaged 6 or more rpg for five straight years (1958-62), starting in his second season.

In 1960-61 he posted a career high 7.9 rpg. Next season the 6-4 Guerin averaged career bests in points (29.5 ppg) and assists (6.9 apg) in addition to posting his final 6-plus rpg season (6.4 rpg).

His rebounding dropped dramatically after that year and he finished his career with a 5.0 rpg average. ..."

"... Jerry West entered the NBA with Robertson in 1960-61 and averaged at least 6 rpg in each of his first six seasons.

Like Robertson, he posted his best rpg average in 1961-62 (7.9 rpg) and he also matched Robertson's 30.8 ppg average that season (West played four fewer games than Robertson and ranked fifth in scoring, which at that time was determined by total points, not average).

The 6-2, 185 pound West was significantly smaller than Gola, Guerin and Robertson, the other top rebounding guards of his era, but he finished his career with 5376 rebounds (5.8 rpg). ... "

"... Magic Johnson made a run at averaging a triple double for a season in 1981-82, his third year in the league. Magic scored 18.6 ppg, ranked second in the league with 9.5 apg and grabbed a career high 9.6 rpg.

In the first 12 years of his career he averaged at least 6 rpg 10 times; in 1980-81 he averaged 8.6 rpg but only played in 37 games and in 1985-86 he averaged 5.9 rpg.

Magic averaged 5.7 rpg in his brief 32 game comeback in 1995-96 and finished his career with 6559 rebounds, the third highest total for a guard, and a 7.2 rpg average, trailing only Gola, Robertson and Sloan. ..."

"... Michael Jordan entered the NBA one year after Drexler and posted similar career rebounding numbers--6175 rebounds (6.2 rpg), including his 2001-02 totals as a swingman for the Washington Wizards. Jordan has averaged 6-plus rpg seven times.

His career best average is 8.0 rpg in 1988-89, a year in which he also averaged a career high 8.0 assists and won his third scoring title with a 32.5 ppg average. Injuries limited him to 18 games in his second season and two retirements further restricted his opportunities to add to his total of 6-plus rpg campaigns.

In his last two seasons with the Bulls he averaged 5.9 rpg and 5.8 rpg respectively. In his first season with the Wizards, Jordan averaged 5.7 rpg. ..."

Basketball Statistics Analysis Referred Concepts:
The true percentage of team possessions used

We know that the 'Usage Rate' is the formula to determine how many possessions a player uses. But which is its significance ?.

If a player keep an account of a high usage of possessions that means he is the one who has the greatest effect of on how well the team performs ?

So if that team is great and he leads the league in 'usage rate' would that make him the best player in the game ?

The team's offense is a measure of how well its high-usage players are shooting: in a good offense, the high-usage player is usually effective; in a bad offense, the high-usage player is usually ineffective.

Photograph: by Patrick Smith Blog

The eBA Basketball Statistics Analysis System doesn't applies "Usage Rate" because it's not really measures possessions and doesn't really have anything to do with a player's defense.

We apply a stat that really measures usage:the percentage of team possessions used while on the floor.

Surely a player using up to 25-30% of team possessions is going to have a big effect on how well the offense performs, good or bad; by contrast, teams can get the best of low-efficiency, high-usage players and, rarely but possible, however have some decent offense.

eBA Encyclopedia Statistics Terminology: Quartile

In descriptive statistics, a quartile is any of the three values which divide the sorted data set into four equal parts, so that each part represents 1/4th of the sampled population.

There are three quartiles. The first or lower quartile (LQ) of a list is a number (not necessarily a number in the list) such that at least 1/4 of the numbers in the list are no larger than it, and at least 3/4 of the numbers in the list are no smaller than it.

The second quartile is the median.

The third or upper quartile (UQ) is a number such that at least 3/4 of the entries in the list are no larger than it, and at least 1/4 of the numbers in the list are no smaller
than it.

To find the quartiles, first sort the list into increasing order. Find the smallest integer that is at least as big as the number of entries in the list divided by four.

Call that integer k. The kth element of the sorted list is the lower quartile. Find the smallest integer that is at least as big as the number of entries in the list divided by two.

Call that integer l. The lth element of the sorted list is the median. Find the smallest integer that is at least as large as the number of entries in the list times 3/4.

Call that integer m. The mth element of the sorted list is the upper quartile.

Sunday's Reflexions on Basketball Statistics:
Basketball Steals & Defense By The Numbers

Data collected since 1988 by eBA Stats.com Team reflects the good and bad of the team’s defense.

We tracked possession-by-possession who was responsible for defending shots, forcing turnovers, committing fouls that resulted in free throws, or stealing the ball including effective ball denial defense.

The data suggests broad defensive principles where guards and perimeter defenders can pressure the ball and make opponents uncomfortable on the perimeter, but always with focus on the team’s force rules that funnel penetration to certain locations.

At those defined locations, the perimeter defender knows he’ll have help from a teammate — usually a big man.

This eBA Stats approach is very valid, and more detailed than what we see at another statistical systems. This kind of information is extremely useful and is being studied during the current eBA Basketball Statistics Analysis System Clinic.

Photograph: from The Chronicle-Telegram

The goal is to steal the ball and create turnovers by always having a defender close to the offensive player, limit the number of open looks at the basket, while simultaneously having big men challenge a greater proportion of the offense’s shot attempts.

This serves to both steal the ball and create turnovers and increase the statistical likelihood of misses.

"... Unlike baseball, with its repeated encounters between pitchers and batters, basketball is not a series of one-on-one contests. In baseball, the game's essence is captured remarkably well by box scores. ..."

"... In basketball, statistics in box scores focus almost entirely on the player with the ball. This omits critical aspects of the game, like teamwork and defense. ..."

"... These blind spots have made many fans and old-school basketball disciples skeptical of statistical analysis. Dean Oliver, author of "Basketball on Paper" and a statistical consultant for the Seattle SuperSonics, has likened attempts to produce an overall player rating to the quest for the Holy Grail. ..."

"... Because plus-minus statistics depend on team performance, they capture almost every contribution a player can make.

In theory, they are an ideal measure of a player's effectiveness. ..."

"... Plus-minus statistics are especially difficult to interpret when the analysis is applied to a small number of games, a point not well understood by many proponents of the statistics. Stable results take more than half a season; stable box-score statistics require only about 10 games. ..."

"... People in the game often claim to know instinctively how to measure intangibles, but salaries suggest otherwise. Teams pay for little more than the glory statistics (points, rebounds and, to a lesser extent, assists). ..."

"... Although steals, blocks, shooting percentage and an ability to avoid turnovers are crucial to a team's performance, players proficient in these aspects are rarely rewarded with bigger paychecks. ..."

Taking Shots:
Tall Tales, Bizarre Battles,
and the Incredible Truth About the NBA
By: Keith Glass

The NBA is in trouble. And as NBA agent Keith Glass describes it–he's part of the problem! If team owners are willing to throw millions of dollars his way for marginal players, why should he be the only one with the self–restraint to say "no?"

In his insightful, funny, and often mind–numbingly bizarre tales of life in the NBA, Keith Glass lets it fly from half–court. He'll tell you how we got to the present state–where an agent who makes millions off the game can't sit through one; why our NBA stars couldn't capture Olympic gold; why one of the greatest high school players he ever saw ended up in Attica prison instead of the NBA; why selfishness has attached itself to the league; and why the game he loves is in dire need of help.

With informative chapters such as "How to Feed Your Family on Only $14 Million a Year," "Eighty–one Feet of White Centers," and "From 6'11" to the 7–Eleven," Glass shatters the myth of NBA marketing: that everything about the game is great, that tickets are worth over $100 apiece, and that as long as the fans in the luxury boxes are happy and weighed down with jerseys and merchandise, all is well.

But have no fear! Keith Glass will not preach about the evils of highlight film slam–dunks and gangsta rap tattoos–he'll just have you falling down laughing as he flagrantly fouls the league that was once the home of Jordan, Magic, and Bird–not to mention Wilt, Russell, Kareem and all the greats in between.

Keith Glass has coached basketball at the high school and college levels (he was an assistant coach at UCLA), and has been a longtime agent for NBA players. He lives in Rumson, New Jersey, with his wife, Aylin Guney Glass, who played professional basketball in Turkey. He is the father of five children—Sami, Tyler, Alex, Maggie, and Lucas.

Sunday's Reflexions on Basketball Statistics:
Does Basketball Defense Win Championships ?

Is defense more consistent than offense ?

Does defense win championships ?

Has the eBA Basketball Statistics Creative Analysis System actually tried to confirm that?

The data from the eBA System Archives proves that there's no fairly large benefit resulting from being offensive oriented or defensive oriented.

Effective teams, specially at the European championship level teams, from where our Archives are operated, have a tendency to be effective at both ends.

Photograph: from Streeter Lecka at Raleigh-Durham

You can hear that defense is more consistent than offense is really not a proper alignment.

It is possible that there is some little evidence that defense may be more significant than offense for winning a championship but in general, however, great champs are very effective at both ends of the floor.

When we analyzed the losing contestant team is where we found they were very effective at one end of the floor and deficient at the other.

In those cases, the losing contestant team was inclined to be a defensive oriented team.

Placing Kobe Bryant's Career in Historical Context

From 20 Second Timeout
By David Friedman
Download source here: ' Placing Kobe Bryant's Career in Historical Context ' by David Friedman

"... The following examples are not intended to dispute or diminish the greatness of Jordan, Johnson and Bird, three players who--by any reasonable standard--must be ranked among the 10 best basketball players of all-time; the point is that they have gradually become viewed as flawless icons instead of human beings who accomplished a lot but also made mistakes, had bad games and were far from perfect.

Keeping that in mind, here are some things that Michael Jordan, Magic Johnson and Larry Bird "would never do"--except for the fact that they actually did ! ..."

"... It is interesting that although most "stat gurus" and many media members insist that Bryant should not even be compared with Jordan many of the players and coaches who competed against both players think that Jordan and Bryant are very similar and some have asserted that Bryant is actually greater than Jordan. ..."

"... It is obvious to any objective observer that Bryant is the closest thing to Jordan since Jordan retired; they have similar body types, for most of their careers they played the same position in the same offensive system for the same coach and they both were the dominant winners in their sport during their respective careers. ... "

"... I have consistently said that I consider Jordan to be greater than Bryant both in terms of accomplishments and overall skill set. Bryant is gaining ground in the first category and is not real far behind in the second department but even after Bryant's "Jordanesque" playoff runs from 2008-10 I would still take Jordan over Bryant in both regards. ..."

"... If I did not understand statistics and/or had some kind of agenda, I would be tempted to say that the above numbers--particularly regarding assists--"prove" that the Lakers are better off when Bryant passes less frequently; of course, such a comment would ignore the perils of making broad conclusions based on a small sample size, it would disregard the very real possibility that Bryant's assist numbers may not be accurate (I have repeatedly documented numerous occasions involving other players when NBA scorekeepers handed out assists that do not meet the rulebook requirements) and--most significantly--it would reflect a simple-minded view of the game by suggesting that the complex interactions of 10 players can be understood by looking at one player's production in one statistical category. ..."

"... Kobe Bryant will be remembered as the best player and most consistent champion of the immediate "post Michael Jordan era"--and I am very proud of the extensive, in depth and objective coverage that I have provided about Bryant. ..."

"... No player has ever singlehandedly won a championship in a team sport but most championship teams have one player who sets the tone with a combination of talent, work ethic, determination, leadership and clutch play. ..."

Basketball Statistics Analysis Referred Concepts:
Basic Basketball Turnovers Statistics Breakdown

We have at the eBA Basketball Statistics Analysis System a basic breakdown of turnovers related to the following two percentages:

1) Opponent turnovers that result in our team steals

2) Opponent turnovers forced that weren't recorded as our team steals

Now, what percentage of all turnovers are steals, and what percentage are non-steal turnovers ?

Photograph: PE.com

From the eBA Basketball Statistics Analysis System archives:

51.4 % of Total Team Turnovers are finally recorded as a steal for the other team: Forced Turnovers.

Therefore 48.6 % of all turnovers are of the non-steal classification: Unforced Turnovers.

Total Team Turnovers are (on average) more than two times the number of opponent steals.

There is some different versions about how many of these Team TO are registered over a season.

But basically you have 3 classes of TO: steals (Forced by the Opponent) ; non-steals attributed to individuals (Unforced); and 'other' team TO (as shot-clock violations).

Each one of these TO cases and the eBA Statistical Registration are described and analyzed in the exposition "Basketball Turnovers Analysis" at the eBA Clinics.

Basketball Registering Stats Referred Questions:
Correctable Referee's Error Rule & Statistics

"... Game under FIBA rules: Team A is on team fouls and the marker is up at the control table showing it. Player A1 commits the 5th. A team foul but instead of awarding the free throws to Team B, one of the officials gave possession to Team B who scored a basket.

The referees on the table buzzed and points out the error of the missed free throws. May the officials give the basket as good and award the "forgotten" free-throws, because it is a "correctable official error" ?

What is the correct rule and, specially, the statistical register of this play ? ..."

Photograph: CSD Eagles

In the year 2000 FIBA modified the Correctable Error rule, so that in this situation if a basket was scored, you can't award also the free throws: it would be penalizing the offending team twice.

Till the 1999 FIBA basketball season the official would have been correct in giving the basket as good and award the "forgotten" free-throws ( and actually also at the NCAA as they has not yet adopted this amendment ).

But after the modification, meanwhile the error of the official is still within the correctable error time structure, the new rule (58.3.3) means that the missed free throws should have been ignored and the ball should have been awarded to Team B on the baseline ( with the possibility of running the baseline as after any successful basket )

See in our forum the 'correctable error' topics and the exposition "Basketball Possessions Statistical Analysis" at eBA ONLINE.

eBA Encyclopedia Statistics Terminology: Scatter Plot

A scatter plot is a useful summary of a set of bi variate data (two variables), usually drawn before working out a linear correlation coefficient or fitting a regression line.

It gives a good visual picture of the relationship between the two variables, and aids the interpretation of the correlation coefficient or regression model.

Each unit contributes one point to the scatter plot, on which points are plotted but not joined. The resulting pattern indicates the type and strength of the relationship between the two variables.

lllustrations

1. The more the points tend to cluster around a straight line, the stronger the linear relationship between the two variables (the higher the correlation).
2. If the line around which the points tends to cluster runs from lower left to upper right, the relationship between the two variables is positive (direct).
3. If the line around which the points tends to cluster runs from upper left to lower right, the relationship between the two variables is negative (inverse).
4. If there exists a random scatter of points, there is no relationship between the two variables (very low or zero correlation).
5. Very low or zero correlation could result from a non-linear relationship between the variables. If the relationship is in fact non-linear (points clustering around a curve, not a straight line), the correlation coefficient will not be a good measure of the strength.

A scatter plot will also show up a non-linear relationship between the two variables and whether or not there exist any outliers in the data.

More information can be added to a two-dimensional scatter plot - for example, we might label points with a code to indicate the level of a third variable.

If we are dealing with many variables in a data set, a way of presenting all possible scatter plots of two variables at a time is in a scatter plot matrix.

Sunday's Reflexions on Basketball Statistics:
About the Efficiency in Different Possession Start Cases

In the eBA System there is a study on the average offensive efficiency in different possession start cases. Is was made by the Prof. Roberto Azar using data from play-by-plays of 1000 games of the Euroleague from 1988.

The research is presented in the eBA Basketball Statistics Clinics, and give us, among a lot of other analysis elements, the order of the starting of the possessions ordered from highest to lowest offensive efficiency:

01 - Steal,
02 - Offensive Rebound after 2p FG missed,
03 - Offensive Rebound after 3p FG missed,
04 - Defensive Rebound after 2p FG missed,
05 - Opponent non-steal turnover,

Photograph: from William C. Greene at Basketball 180

06 - Defensive Rebound after 3p FG missed,
07 - FT made,
08 - 2p FG made,
09 - 3p FG made,
10 - Start of quarter,
11 - Defensive Rebound after FT missed.

Friday Press Clippings:
Are NBA rebounds consistent because of talent or opportunities ?

From Sabermetric Research
By Phil Birnbaum
Download source here: ' Stumbling on Wins: Are NBA rebounds consistent because of talent or opportunities? ' by Phil Birnbaum

"... When we look at consistency, ... we see that 90% of the variation in a player's per-minute rebounds is explained by a player's per-minute rebounds the previous season. There appear to be no statistics in baseball or football that are as consistent as rebounds in basketball. ..."

"... When the authors say "there are no statistics in baseball as consistent as rebounds" ... well, they didn't include saves. I don't know for sure if saves have a higher r-squared or not, but I'd certainly be willing to bet they do. ..."

"... Well, it's probably true that NBA players have spent more time in games than NFL players, but I'm not sure why that's important. Why does playing fewer games (but still a lot of games -- a regular lot, rather than a huge lot) make you less consistent? ... "

"... In that case, you might see a QB go from 20% to 25% in some measure more often than a basketball player goes from 20% to 25% in a similar measure. But if that were true, wouldn't the QB be improving throughout his entire career, given that he plays only 16 games a season? ..."

"... See? It's just opportunities. Those other explanations, about teammates an inexperience, might be factors too. But they're minor factors at best, and, without evidence, they're just speculation. ..."

"... The "opportunities" for rebounds aren't playing time opportunities, but rebounding opportunities. The idea is that every player has a different chance of being in position to handle the rebound. ..."

"... Another way to say this is that "a good metric must properly take account of differences in opportunities" (which is really your argument).

We can't evaluate a running back based on yards gained if we don't know how many carries he had. We can't evaluate a QB's passing yards without knowing his attempts.

And we can't properly evaluate a rebounder without understanding how many effective rebound opportunities his team gave him (a statistic which isn't recorded). ..."

Basketball Statistics Analysis Referred Concepts:
Tall Players and the Winning Percentage Statistics

There is at the eBA Basketball Statistics Creative Analysis System a research about the influence of the tall players in the winning percentage and the game statistics evolution of the outside and inside players in this game dominated by giants...

Some data to go on with this question and the discussion: in fact, there is in the eBA Basketball Statistics Analysis System a research about the influence of the tall players in the winning percentage and the game statistics evolution of the outside and inside players.

And some data about... only three teams won the NBA ring without a 2.13 m player in their opening quintet in the last 25 years:

Photograph: angry asian man

... the Detroit Pistons in 2003-04 ( with Rasheed Wallace, 2.11, as the tall man of the opening team ), newly the Pistons in 1988-89 ( with Laimbeer, 2.11, as the tall man ) and the Sixers of 1982-83 ( with Moses Malone, 2.08, as the tall of the opening quintet ). And, speaking about the Euroleague, only one team: the Panathinaikos of 2001-02, with Alvertis, 2.06, as the tall man of the team.

And to close this the first section of the answer, with all that was said we reach to the 'Seven Feet Theory', which is supported by recognized NBA scouters: to win actually a championship you must have a 7 feet ( 2,13 m ) player in the middle of the paint area.

Basketball Registering Stats Referred Questions:
A Traveling Turnover & a 8/10 seconds backcourt violation

"... A1 jumps and shoots, but B1 taps the ball and is still in A1 ones hand. A1 returns with ball that never left his hand. Is this jump ball, traveling, or a block shoot? B1 just barely tap the ball in the shooters hand. And what the stats men rule ? ..."

eBA Basketball Statistical Registration=
As you related this play we have a Traveling Turnover against A1 and a Steal from B1, the player deflecting, or team player, depending upon the situation.

Photograph: zimbio.com

"... The 8 / 10 seconds time limit rule violation is a PERSONAL or TEAM turnover ? FORCED or UNFORCED ?
By the way, all the basketball leagues have this rule ? Any difference ? ..."

eBA Basketball Statistical Registration=
The 8/10 seconds backcourt violation is generally a TEAM TURNOVER, being FORCED or UNFORCED depending upon the opponent's action: if it is as result of an all or half court press defense (FORCED) or a defender's error (UNFORCED).

The NCAA Women's rules are the only ones without backcourt count.

eBA Encyclopedia Statistics Terminology: Bias

Bias is a term which refers to how far the average statistic lies from the parameter it is estimating, that is, the error which arises when estimating a quantity.

Errors from chance will cancel each other out in the long run, those from bias will not.

The following illustrates bias and precision, where the target value is the bulls eye:

	Precise	Imprecise
Biased
Unbiased

Example
The police decide to estimate the average speed of drivers using the fast lane of the motorway and consider how it can be done. One method suggested is to tail cars using police patrol cars and record their speeds as being the same as that of the police car.

This is likely to produce a biased result as any driver exceeding the speed limit will slow down on seeing a police car behind them. The police then decide to use an unmarked car for their investigation using a speed gun operated by a constable.

This is an unbiased method of measuring speed, but is imprecise compared to using a calibrated speedometer to take the measurement.

Sunday's Reflexions on Basketball Statistics:
About the Game Pace and the Turnovers

According to a research of the eBA Basketball Statistics System about the influence of the 'game pace' on the 'turnover ratios' of individual players:

...there is a connected increase in the number of TO due to pace: as pace increases, players/teams get more TO/Min and TO/G.

Therefore we may suppose the sooner your team shoots the ball, the less probably you have a chance for a TO. Or that time of possession is what's mutually related to TO.

But, while the presumption is that a faster pace means more errors and more turnovers, if you shoot the ball before you pass it, you turn the ball over less.

So, generally, turnover rates do not become larger with quicker pace.
In this case, you wouldn't expect players' turnover rates to vary too much.

Photograph: The Dream Shake

Many other factors could have an effect upon TO rates/possession used or touch year to year:

 • different players in the same organization

 • modifications to an organization that does not suit a particular player's style

 • injuries (players depending on first step with knee/ankle injuries, and injured wrist, etc.) ...

Statistical Tests for the Hot-Hand in Basketball in a Controlled Setting

From University of Wisconsin
By Robert L. Wardrop
Download source here: ' Statistical Tests for the Hot-Hand in Basketball in a Controlled Setting ' by Robert L. Wardrop

"... When I watch basketball on television, it is a common occurrence to have an announcer state that some player has the hot-hand. This raises the question: Are Bernoulli trials an adequate model for the
outcomes of successive shots in basketball? ..."

"... In this paper I consider a statistical analysis of basketball shooting in a controlled (practice) setting, with special interest in the hot-hand. ..."

"... Throughout the two papers the researchers refer to the alternative as being “the hot-hand.” For the two test statistics considered, the runs test and the test of fit, the hot-hand alternative, whether it means autocorrelation or nonstationarity, is naturally a one-sided alternative and should therefore, in my opinion, have a one-sided test. ... "

"... Each player attempted 100 shots from a location at which he or she was believed to be about a 50 percent shooter. Before each shot a player would bet high or low and was advised to bet high if and only if he or she felt confident about the pending attempt. A success on a high bet would earn the shooter five cents, while a miss would cost four cents; for a low bet the values were two and one cents, respectively. The data analysis strategy and conclusions are presented in the following passage, ..."

"... In summary, there are several reasons to believe that Katie’s shooting is more complex than Bernoulli trials. The frequency and size of the hot-hand may or may not match the expectations of many persons, but it is too simplistic, I believe, to assume that Bernoulli trials are always appropriate.

The reader is encouraged to collect data and use the ideas of this paper to analyze them. ..."

May 2010 eBA sketball Statistics Case Study Conclusion

Different Situations in a Basketball FT... Case Study

"... A1 shoots a free throw and fails to hit the rim.


 • case a) A1’s failure to hit the rim is caused by B5, who jumps into the lane and bats A1’s throw away, or
 • case b) A1’s shot misses without any responsibility on the part of Team B, or
 • case c) A1’s shot misses and A1 steps into the lane too early, or
 • case d) A1’s shot misses and A3 steps into the lane too early, or
 • case e) A1’s shot misses but B5 steps into the lane too early.

What is the statistical registration according to the eBA Basketball Statistics Analysis System in each one of the given situations, including the type of the registration ( close, long, disputed or undisputed rebound, etc...) ... ?"

Conclusion:
eBA System Statistics Fundamentals:
A player should not be charged for a shot from the field influenced by the illegal actions of himself or herself, or any teammates or opponents unless the shot results in a FGM.

Photograph from flickr

eBA Basketball Statistical Registration:

• In (a) do not charge A1 with a FTA, B5 will be charged with a Class B technical and Team A will receive two free throws. Charge B5 with an Unforced Turnover in the TF category and Team A with an Unforced Steal;

• in (b) the violation will be the only one penalized. Therefore, charge A1 with a FTA and credit Team B with a dead-ball rebound;

• in (c) do not charge A1 with a FTA, charge A1 with an Unforced Turnover unless Team A retains the ball. The violation for stepping into the lane caused the ball to become dead before the shot missed the rim;

• in (d) do not charge A1 with a FTA, charge A1 with an Unforced Turnover unless Team A retains the ball. The violation for stepping into the lane caused the ball to become dead before the shot missed the rim;

• in (e) this will be ruled a double violation and the possession will be determined by the alternating-possession rule. Charge A1 with an Unforced Turnover unless Team A retains the ball.

This Case Study was presented as every 10th. day of each month, on May 10th, 2010 in our eBA Portal: were sent 287 answers, 221 partial answers and 46 totally correct, that's means including all the options, registrations and qualifications.

Basketball Statistics Analysis Referred Concepts:
When a Shooting Foul is called ? - Statistics Registration

The concept that the player must make a throwing motion in order for it to be a shooting foul seems to convey no meaning. The player must intend to do so, but if contact prevents the completion of the shot, it can still be a shooting foul.

An example about this concept: A1 is a few feet away from the basket, facing the side of the backboard. When A1 starts what appears to be a try for a goal, he is in front of the backboard and well positioned to score. B1 illegally bumps A1 while A1 is airborne, moving A1 to a position where he is now behind the backboard. A1 (still airborne) now realises that a shot is impossible from behind the backboard, so he passes the ball to A2, who is standing near the free throw line.

Photograph from Sports Bar

The referee must call a foul on B1 and award two shots to A1, as he was in the act of shooting when the contact happened, on the contrary it would penalise the shooter because he was smart enough to try and continue playing. The fact that he eventually passed the ball is really of no consequence.

Every time the official judges that the player is making a continuous attempt for goal, they get shots, no matter how early in the drive the contact occurs, no matter in the drive is completed or no.

The eBA statistics registration is simple: a made foul and a received foul and the result of the free throws, simply. If there was a pass before the action, it would be considered an assist with foul. See in the Stats Forums the posts about basketball assists.

Basketball Registering Stats Referred Questions:
Is it Possible to Register a Double Foul ?

"... A player goes to the basket with the ball, two defenders go to stop him and make contact:

1) Is it possible to call a personal foul on both defenders if they make contact with the offensive player ?

2) What is, in this case, the stats rule ? If the answer to 1) is positive, both defenders receive a "Foul Made" ?

3) If so, the total of teams fouls made will not be real....

Which is the rule of this situation and, specially the statistician rule according to the eBA Basketball Statistics Analysis System ? ..."

Photograph: the east coast bias

eBA Basketball Statistical Registration=
This case is no so frequent, but possible. The call is about the first foul ignoring the subsequent. Only if the second contact is unsportsmanlike it is called.

No case that the stats-men rules both players a foul given: only to the first foul made in accordance with the referee's call.

See in our forum the 'double fouls' topics and the exposition "Basketball Personal Fouls Statistical Analysis" at eBA ONLINE.

This Week Basketball Book eBA DVICE !

Same Knight, Different Channel
By: Jack Isenhour

Basketball legend Bob Knight is fond of saying that he has never gotten over West Point. In Same Knight, Different Channel, Jack Isenhour takes him at his word. A player on Knight’s first West Point team, Isenhour shows how the controversial coach has changed little from his early days at the academy, temper tantrums and all. Knight made up his mind there to "win-gotta win" and follows that philosophy to this day.

Knight’s sentiment was in step with the core value of "there is no substitute for victory" at West Point, where soldiers were being trained to fight and win the next war.
So it came as little surprise following Knight’s 18-8 record in his inaugural 1965-66 season-a season in which the twenty-five-year-old hot-headed coach berated officials, totaled chairs, and got into his first shouting match with an athletic director-that West Point chose to keep the young Coach Knight on.
What’s a tantrum or two in the name of winning? With that, "Bobby T" was born. Knight’s bad-boy persona-the hair-trigger temper, the acting out, and the defiance-was codified as at least tolerable, if not acceptable, behavior.

Relying on firsthand experiences and interviews with teammates, administrators, and Knight himself, Isenhour traces the pattern of misbehavior established during Knight’s inaugural year at West Point, during his last days at Indiana, and to his reemergence at Texas Tech.

The result is the most even-handed portrait of Knight to date. In a narrative both lively and irreverent, Same Knight, Different Channel demonstrates who Knight is today and shows how he was shaped by his experiences at West Point, ending with a thought-provoking discussion of just what it takes to play, coach, and win in the high-pressure world of college basketball...."

Jack Isenhour an award-winning television journalist, was a seldom-used guard on Bob Knight's first Army basketball (1965-66). His premise is that the Knight we know today--controversial, temperamental, successful--was forged by his tenure at West Point when he became the Cadets' head coach at the ridiculously young age of 25. The raw material was there: a fierce competitor in high school and college, Knight was the kid skidding around the court diving after loose balls.

When Army coach Tates Locke resigned to take another position, he recommended that his young assistant succeed him. Knight's inherent competitiveness flourished at West Point during the Vietnam era.
He developed a style--stifling defense, patient offense--that maximized the skills of players who were not big and not heavily recruited.

Filled with great anecdotes from former players and Isenhour's self-deprecating replays of his time--yesterday and today--with Knight, this is a compelling look at the early career of a man who will soon become the winningest college coach in history.

Sunday's Reflexions on Basketball Statistics:
Center as a Full-time Basketball Position

Let us now have a closer look to the first two changes proposed here by Dennis Hans. He thinks that we’ll not only reduce the threat of foul trouble, we’ll remake center into a full-time basketball position, where quickness, creativity and skill, rather than brute strength or a gift for flopping, are paramount.

"... 1) Make non-brutal illegal screens a loss-of-possession violation, like traveling. Only dirty picks – sticking out an elbow, forearm or bony knee – will be a foul.

Probably 90 percent of illegal screens fall into the non-dirty category.

2) Quit treating intentional fouls as if they were non-intentional. Current penalties for the latter are fine; for the former, they are so weak that they function as rewards.

Photograph: Mike Ransdell from Canada.com/

Most intentional fouls – grabs by beaten or outmanned defenders to abort fast breaks or halfcourt drives; hugs and muggings to prevent layups and dunks – are based on the premise that the opposing team is less likely to score two points if they have to restart their offense by inbounding the ball or step to the line for a pair of free throws than if the fast break, drive or power move had continued. ...

If we make the penalty an actual penalty – two points for the fouled player, and his team retains possession of the ball – refs will never have to invoke the rule because no one would be so stupid as to intentionally foul.

We’ll have fewer stoppages of play, more fast breaks, less roughhousing, and fewer fouls, particularly by centers. ..."

And how we adapt these proposals to the basketball statistics registration?

Basketball Coaches Digest:
GOODBYE, MAESTRO ! Legendary John Wooden dies at 99

John Wooden, college basketball's gentlemanly Wizard of Westwood who built one of the greatest dynasties in all of sports at UCLA and became one of the most revered coaches ever, has died. He was 99.

The university said Wooden died Friday night of natural causes at Ronald Reagan UCLA Medical Center, where he had been since May 26.

Wooden remained beloved by many of his former players, several of whom visited him in recent days to say their goodbyes.

Among them was Bill Walton, whose voice caught as he spoke of the man he hailed as a teacher first and a coach second.

"He's the greatest," Walton said the night before Wooden's death. "We love him."

Jamaal Wilkes said he recognized what he called "that little glint" in Wooden's pale blue eyes.

During his second visit Wednesday night, Wilkes asked Wooden if he recognized him.

"His glasses fogged up, and he had to clean his glasses," Wilkes said. "He looked at me and said, 'I remember you, now go sit down.'"

Los Angeles Dodgers manager Joe Torre and current UCLA coach Ben Howland were among Wooden's final visitors.

"I just enjoyed him and the twinkle in his eye," Howland said, noting Wooden told a few jokes from his hospital bed. "I'm just the steward of this program. It's always going to be his program."

Jim Harrick is the only coach in the post-Wooden era at UCLA to win a national championship. When the Bruins reached the 1995 Final Four in Seattle, Harrick repeatedly urged Wooden to attend. He had stopped going after his wife died 10 years earlier.

"You don't know how stubborn he was," Harrick said by phone from Orange County, Calif. "Finally, he did come, and it was a tremendous thrill."

With his signature rolled-up game program in hand, Wooden led the Bruins to 10 NCAA championships, including an unmatched streak of seven in a row from 1967 to 1973.

Over 27 years, he won 620 games, including 88 straight during one historic stretch, and coached many of the game's greatest players such as Walton and Lew Alcindor - later known as Kareem Abdul-Jabbar.

"It's kind of hard to talk about Coach Wooden simply, because he was a complex man. But he taught in a very simple way. He just used sports as a means to teach us how to apply ourselves to any situation," Abdul-Jabbar said in a statement released through UCLA.

"He set quite an example. He was more like a parent than a coach. He really was a very selfless and giving human being, but he was a disciplinarian. We learned all about those aspects of life that most kids want to skip over. He wouldn't let us do that."

Wooden is the only person to be inducted into the Basketball Hall of Fame as both a player and a coach.

Friday Press Clippings:
Defining the Value of a Superstar

From 20 Second Timeout
By David Friedman
Download source here: ' Defining the Value of a Superstar ' by David Friedman

"... How exactly should a player’s value be defined? One way to answer this question is to look at the player’s impact on his own team.

At 82Games.com, Roland Beech compiles several statistics that, taken together, give an indication of which players are most important to the performance of their teams.

"On court" and "off court," as the names suggest, reflect a team’s net points per 100 possessions when a given player is on the court and off the court respectively. ... "

"... A player’s on court and off court numbers are of course affected by the performances of his teammates so it is difficult to project whether a player would do better or worse on a different team.

A player whose numbers are boosted by being surrounded by talented players may not be able to be that productive on a weaker team; conversely, a superstar who is surrounded by a weak supporting cast may have his numbers dragged down by his teammates’ miscues. ..."

"... These statistics alone do not definitively answer the question of who was the NBA’s Most Valuable Player but they lend some context to the discussion. ..."

Basketball Statistics Analysis Referred Concepts:
The PPR - Assist/Turnover Rating

The PPR - Assist/Turnover Rating is an assist to turnover ratio which is much better than the simple assists divided by turnovers ratio which is often used by the media.

Turnovers were not kept as an official stat by the NBA prior to the 1977-78 season so PPR is only displayed or accurate after this that season.

This formula was used by John Hollinger in his book Pro Basketball Forecast: 2005-06 (Pro Basketball Prospectus).

PPR - Assist / Turnover Rating = (((ASTS*.66)-TO)*100) / Minutes

We modify, apply and discuss this method in the eBA Basketball Statistics Analysis Clinics: from the 2nd. Exposition "Basketball Statistical Formulas Revision".

Basketball Registering Stats Referred Questions:
Loose Ball and pushed by own teammate

"... Loose ball and Team B player gets the ball and turns very quickly to shoot at the basket, but when he goes up for the shot he is pushed by another Team B player in the loose ball struggle yet.

The official blew the whistle and then realized that it was his own teammate that had contact with him.

Which is the rule of this situation and, specially the statistician rule according to the eBA Basketball Statistics Analysis System ? ..."

Photograph: NBA Tipoff

eBA Basketball Statistical Registration=
In an inadvertent whistle situation like this, the official must determine where the ball was at the time of the whistle:

1) the ball is still in the shooter's hands: ball becomes dead immediately, no goal can be scored, and team B gets the ball back. No statistical register, out of the play-by-play story.

2) the ball was in the air: the goal counts if it goes, and the games goes with a jump ball or the Alternating Possession arrow, its depends by the league.

3) if the ball had been secured on a rebound already: that team receives the ball for a throw-in.

See in our forum the 'loose balls' topics and the exposition "Basketball Posessions Statistical Analysis" at eBA ONLINE.

All the terms in this answer are explained widely at The Global Basketball Encyclopedia and in eBA ONLINE.

Sunday's Reflexions on Basketball Statistics:
About the Basketball 'Assist-Turnover Ratio'

Reading the 'assist-turnover ratio' from the box-scores, where a player's Ast/TO ratio start to help his team's offensive effectiveness ?

It is clear this level must would be higher for a point guard, but which are the statistical levels ?

Both statistics categories assists and turnovers matter when we note at the European Basketball eBA Archives that 7 of the top 10 AS/TO players are on playoffs teams and of course it does have a positive effect.

 • turnovers are a four factor category according to Dean Oliver's "Basketball on Paper" book;

 • assists suggest good passing and have positive impact on at least 2 of the other three (FG% and FT/FG);

 • TO do not help the offense, but Pts / Reb / Ast do;

 • assists have positive impact on offensive rebounding if the good passes creates a need for help defense;

 • the eBA Basketball Statistics Analysis System separates out 'TO resulting from passes' in our calculations;

 • assists also allow some of the players to focus more on rebounding than looking for their shot;

 • from the eBA Archives top 5 teams on raw assists played the playoffs but 3 of the bottom 5 played too;

 • assists are not one of the four factors categories according to Dean Oliver's "Basketball on Paper" book;

 • as you can see below, the results are different if the PG is also a shooter and/or rebounder - all this things create turnover opportunities-, than if he just brings the ball up and passes;

 • you can play with the following numbers taking into account that this is only a new eBA Research and the break-even points may very well be different for each position:

Top 20 overall AS/TO Ratio are for point guards 2.45, shooting guards 1.75, small forward 1.55, power forward 1.15 and center something about 0.85.

Friday Press Clippings:
Game Related Statistics Discriminating
Between Starters and Nonstarters Players
in Women's National Basketball Association League (WNBA)

From Journal of Sports Science & Medicine
By Miguel. A Gómez, Alberto Lorenzo, Enrique Ortega, Jaime Sampaio and Sergio. J Ibáñez
Download source here: ' Game Related Statistics Discriminating Between Starters and Nonstarters Players in Women's National Basketball Association League (WNBA) '

"... The aim of the present study was to identify the game-related statistics that allow discriminating between starters and nonstarter players in women's basketball when related to winning or losing games and best or worst teams. ..."

"... Nowadays, basketball coaches and performance analysts have used game-related statistics to study team's and player's performance in different game contexts.

In this particular topic, published research has been focussed specifically on men's teams. However, available research on women's basketball and also in comparing both genders' performances is very limited. ... "

"... This fact suggests a need to improve the knowledge about women's basketball, which is very limited and generally based on men's norms, in particular to know women's player performance and their contributions to team performance according to their player status.

Thus, the aim of the present study was to examine the differences in game-related statistics between basketball starters and nonstarters players when related to game outcome and team quality in Women's National Basketball Association League (WNBA). ..."

"... There are rule differences between the sample studied (WNBA) and the European basketball. In particular, Reimer, 2005 compared FIBA and North-American rules, and found the following differences for WNBA 2005 season:
i) two time periods of 20 minutes instead of four periods of 10 minutes;
ii) thirty seconds in each ball possession instead of twenty four seconds;
iii) six fouls per player instead of five personal fouls; and
iv) seven team fouls to go to the free-throw line instead of five team fouls.

Therefore, despite the present results are characterizing the highest level of women's competition; extrapolation to other contexts should consider differences in rules. ..."

"... The results found in the present study indicate that men's and women's teams have different playing styles. These differences may reflect that women's teams play with slower game pace, probably women's teams attack more frequently versus zone defenses, which require more emphasis on team and less on individual defense.

Thus, women's teams need more passes and structured offenses to break the opposite defense as pointed out by the importance of offensive actions (assists and 2-point field-goals). On the other hand, men's teams have higher game pace.

This suggest better physical parameters that allow to defend with higher intensity, more physical contact and with a game based on defensive rebounds to initiate their ball possessions, and fouls trying to stop the opposite offence. ..."

Basketball Statistics Analysis Referred Concepts:
Basketball Steals and Defensive Efficiency

In the current eBA Annual Basketball Statistics Clinic there is a debate about basketball steals: is a good number of steals a good indicator for the efficiency of the defense ?

Some thoughts to begin the discussion:

 • ...players or teams with the best steals averages are not as a highly likely consequence the best defensive players or steals...

 • ...if players go for too many steals, the probabilities are their defensive efficiency including everything is set at a disadvantage from that...

 • ...steals percentage (steals per possession) is a good statistic to consider...

 • ...declaring as an attribute or quality a defense on steals isn't going to be as being marked by a favorable outcome as one based on forcing misses...

Photograph from Jeff Vendsel at Marin Independent Journal

 • ...if your aggressive style defense is more impressive than your team playing a more conforming to a standard defense, you'll have to examine and note the similarities or differences of your numbers with something...

The discussion and my analysis will continue on the thread "Steal Statistics: Cases & Registration" at the Processing Statistics Board.

eBA Stats Group is growing faster than ever before !
"... Therefore, in order to improve quick web contents accessibility and assure free availability of our eBA Group of Sites to our Full Registered Members, during the eBA Forums Discussions, the eBA Encyclopedia consultations and the eBA Basketball Clinics Online participation, the eBA Annual Basketball Statistics Clinic Participants recommended and the eBA Team decided the following:

1) To admit new eBA Members which perform their registration ( on any eBA
website ) ONLY from their official email address given by their ISPs ( Internet Service Providers ), and include our email in their e-mail whitelist, not allowing from today ANY activity from free email services accounts.

2) The eBA Forums Discussions and the current Annual eBA Clinic are being permanently affected by interrupted chat meetings connections, waste of time, and loss of important documents which does not arrive to the people, and must be resent one again... and again !

3) In the eBA Forums: to reserve to eBA Full Members ALL the boards dedicated to basketball statistics, currently open to all the anonymous guests.

4) In the eBA Encyclopedia: to maintain open to the anonymous guests ONLY the terminology glossaries, reserving to eBA Full Members ALL the other sections.

5) In the eBA Clinics: the changes and the format of the future eBA Basketball Statistics Clinics, shall be published at the end of the current eBA Annual Basketball statistics Clinic.

6) No changes will be performed in the open eBA Blogs, eBA Portal, eBA on Facebook and eBA Twitter.

7) Finally, to our 10.000+ Newsletters Subscribers with legal email addresses, all the technical newsletters, basketball statistics articles and documents SHALL NOT BE SENT AGAIN to free emails in case of email bouncing.

Free email services are supported by advertising, especially web-based email services. Other free email services, such as POP mail services, make their living by reselling or reusing the email information. In both cases, those free email services affects the web contents accessibility and free availability to our intercommunicative sites.

Free email services often market themselves as being "free for life"... but every week, several free email providers disappear, either through lack of funds, or buried under systematic abuse from spammers. And leave us with a ton of bouncing email !

And finally, here's something that most free email providers will never admit: because their services are often abused by spammers, we may find that some ISPs ( Internet Service Providers ) have taken to automatically blocking mail coming from some free email domains.

In consequence, we find that our messages will never get to certain people, no matter how many times we send them out; that's because their ISP is filtering the mail before they get a chance to see it!

This is one of the reasons why free email addresses from good companies as gMail and Yahoo, are fine for individual use, but not a good idea if our eBA Group of Sites, including the eBA Forums and the eBA Clinics, depends on people getting through to us !

Thanks a lot for going on wih us during these 12 years ! ..."

Basketball Registering Stats Referred Questions:
Technical Foul and Wrong Basket

"... A16 does is injured and does not play in the game but while sitting on the bench during the game shouts at the referee and receives a technical foul. How we register this play ? Turnover ? Game Played ?

And what is the statistician rule according to the eBA Basketball Statistics Analysis System ? ..."

eBA Basketball Statistical Registration=
Charge A16 with at technical foul but do not credit him with a game played and enter '0' under minutes played.

Photograph: LIFE

"... To whom are credited the points scored in the wrong basket ?
To any player ? To the opponent captain ?
And what the stats rule ? Turnover ? ..."

Points scored in the wrong basket are never credited to a player, but are credited to the team in a footnote. Points awarded for basket interference or goaltending by the defense are credited to the shooter. When a live ball goes in the basket, the last player who touched the ball causes it to go there ( from the Instructions & Rules Coverage - Scoring 9. ).

See in our forum the 'technical fouls' topics and the exposition "Basketball Personal Fouls Statistical Analysis" at eBA ONLINE.

Basketball Books Review: The Weekly eBA DVICE !

Basketball on Paper
Rules and Tools for Performance Analysis
By Dean Oliver

Journey "inside the numbers" for an exceptional set of statistical tools and rules that can help explain the winning-or losing-ways of a Basketball team. Basketball on Paper doesn’t diagram plays or explain how players get in shape, but instead demonstrates how to interpret player and team performance.

Dean Oliver highlights general strategies for teams when they’re winning or losing, and what aspects should be the focus in either situation. He describes and quantifies the jobs of team leaders and role players, then discusses the interactions between players and how to achieve the best fit. Oliver conceptualizes the meaning of teamwork and how to quantify the value of different types of players working together. He examines historically successful NBA teams and identifies what made them so successful individual talent, a system of putting players together, or good coaching.

Oliver then uses these statistical tools and case studies to evaluate the best players in history - such as Magic Johnson, Wilt Chamberlain, Bill Russell, and Charles Barkley - and how they contributed to their teams’ success. He does the same for some of the NBA’s "oddball" players - Manute Bol, Muggsy Bogues, and Dennis Rodman - and for the WNBA’s top players.

Basketball on Paper is unique in its incorporation of business and analytical concepts within the context of Basketball to measure the value of players in a cooperative setting.
Whether you’re looking for strategies or new ideas to throw out while watching the ballgame at a sports bar, Dean Oliver’s Basketball on Paper will give you amazing new insights into teamwork, coaching, and success.

Sunday's Reflexions on Basketball Statistics:
Possessions & the Strength of a Team

The strength of a team is not established as the end result of a process by how many more opportunities at scoring it gets ( what our eBA Basketball Statistics Creative Analysis call "plays" ), but on the contrary how much better it is at scoring with the possessions it has.

There's no "bonus" because possessions are imprecise but fairly close to be equal between a team and its opponent in any determined game. The way we define possessions (see here this excellent thread in this forum: Basketball Possessions: About the Concept, is the time from when one team gets the ball to when the other team gets it back.

Possessions have built-in attributes that make them unmeasurable utilitarians, the largest amount of which being that the number of possessions between a team and their opponents are identical.

A selected excerpt from the discussions at the eBA Annual Analysis System Clinic Chat about this topic "Basketball Possessions".

Friday Press Clippings:
Effects of consecutive basketball games
on the game-related statistics that discriminate winner and losing teams

From The Free Library
Download source here: ' Effects of consecutive basketball games on the game-related statistics that discriminate winner and losing teams '

"... Performance analysis in ball team sports such as basketball is a fundamental tool for coaches, allowing them to have valid and reliable information concerning their team and opponents.

Generally, coaches and researchers use this information to identify the most valuable players and the importance of certain specific roles, to assess the impact of rule changes, to investigate the home advantage or to evaluate the participation in the game by starting and reserve players, with the goal of determining how each player contributes to team performance. ..."

"... The descriptive results and univariate differences from both seasons of the under-20 league for each game played are presented in Table 1. Winning teams in this competition had better values in all game-related statistics, with the exception of 3 point field goals and free throws missed and turnovers (p = 0.05).

The main effect of game number was only identified in turnovers, with a statistical significant decrease between the second and third game. No interaction was found in the analysed variables (Table 1).

The results from the discriminant analysis are presented in Table 2. Overall function reclassifications were high for all three analyses (see Table 2).

The structural coefficients allowed identifying the two-point field goals made, the defensive rebounds and the assists as common to the mean vectors that discriminate winning and losing teams in all three games. Additionally, only the three-point field goals made (SC = -0.34) has contributed to discriminate teams in game three. ... "

"... Overall team performances (as measured by game-related statistics) along the three consecutive games were very similar, thus, not confirming an accumulated fatigue effect.

The identification of a decrease in turnovers between the second and third consecutive game strengthened the previous statement. However, the discriminatory power of the three-point field goal in the third game suggested that winning teams were able to shoot better from longer distances and this could be the result of exhibiting higher conditioning status and/or the losing teams' exhibiting low conditioning in defense.

Facing these results, basketball coaches (and players) may benefit from being aware of this small variation in game determinant related statistics. Also, they could benefit from using offensive and defensive strategies in the third game allowing for exploring or hide the tree point field-goals variable ..."

Basketball Statistics Analysis Referred Concepts:
Registering Each Shot Related to Game Situation

The eBA Basketball Statistics Analysis System register each shot related to:

 • the game situation (time and score);

 • ball location (sideline or endline);

 • player location ( location of shot in our 15 zones basketball court diagram );

 • type of shot (shot selection);

 • shooting clock (seconds remaining);

 • shot result ( made or missed ) and

 • offensive and defensive alignments for each one of the shots.

Photograph from notebooks.com/

The general character and site of the shot attempt can be a manifestation of the stage of difficulty:

1) End-line plays present a bigger menace than sideline out of bounds;

2) In the main, inbounds plays have both inside and outside choices with a condition to keep from performing a 5 second violation;

3) As a whole the first precedence of the defense against end-line out of bounds plays is impeding an easy basket at the rim.

The basketball statistician must knows that The achievement of their objective by the offense or defense returning from a time out in closely contested end game situations are more significant than others - these are about entirely sideline plays

The eBA Basketball Statistics Analysis System also registers the success rates of a specific team or coach after a timeout, both the offense and defense should are analyzed.

Basketball Registering Stats Referred Questions:
Rules without Location Reference

"... Team A is over the limit and Team B has possession at his backcourt.

Team A player make a personal foul in order to provoke a free throws situation: the free throws must be thrown or only when the middle line is crossed and it may be an offensive foul ?

And what is the statistician rule according to the eBA Basketball Statistics Analysis System ? ..."

The question is not clearly formulated, but we'll try to understand the following:
The Rules tell us that a personal foul is a player's fault which implies illegal contact with an opponent, being the ball live or dead.

Common examples are holding, charging, tripping, blocking, pushing, or interference. A personal foul results in either a player taking free throws or a team losing possession of the ball.

So, the Rules states that beyond a given number of fouls: 4 team fouls per NBA, FIBA or ULEB period; 8 per WNBA half; 7 per half in college the team is over the limit". See the eBA Global Basketball Encyclopedia:

"Each team is allowed the given number of fouls per quarter or half for which no free throws are assessed ( unless they are committed against players in act of shooting ); after the given number of fouls a team is said to be "over the limit" and free throws are assessed on all subsequent fouls. This team is also said "to be in the penalty".

The basketball rules don't make any reference about the location of the player at the moment the personal foul is committed, with reference to backcourt or frontcourt, only they must be between the court legal limits. So, any statistical analysis rules refers to this situation too.

See in our forum the 'personal fouls' topics and the exposition "Basketball Personal Fouls Statistical Analysis" at eBA ONLINE.

All the terms in this answer are explained widely at The Global Basketball Encyclopedia and in eBA ONLINE.

Basketball Books Review: The Weekly eBA DVICE !

Game
By: Walter Dean Myers

Drew Lawson lives and breathes basketball. He plans to use basketball as his ticket out of Harlem, and everyone knows it. The problems start when Coach "House" Hauser changes the game plan.

The Lawson family is a bit unusual for their neighborhood. Drew is lucky to have both a mom and dad living under the same roof, and although money is a struggle, both parents work. He and his sister have been raised to value life and set high goals. News from their neighborhood only makes the paper when it is bad news. Shootings, stabbings, and robberies are the usual stories, and Drew's mother frets when those stories involve young people.

The Chargers basketball team could offer Drew a chance at a better life. He is a decent player and has his sights set on playing Division I college ball in hopes of being a future NBA player. As a star Chargers' player, it just might be possible. Unfortunately, it seems that Coach House has other plans.

It is mid-season and suddenly Coach House has brought in two new players - a couple of white players. That doesn't bother Drew and his team too much until it becomes evident that Coach plans to start these new players in positions that clearly threaten Drew's game. What is Coach trying to do? Is there a method to his madness or is Drew's future at stake?

GAME is set in Walter Dean Myers' home territory in Harlem, and is filled with his trademark characters and plenty of action. Readers hear Drew's story in between bouts of realistic play-by-play basketball scenes. Myers fans as well as basketball lovers will find this a satisfying read.

Sunday's Reflexions on Basketball Statistics:
Formula that separates offensive and defensive basketball rebounds

The eBA Basketball Statistics Analysis System, which is being studied in the eBA System Annual Clinic, applies a formula that separates offensive and defensive rebounds when we analyze the team and player rebounding percentages and performance.

The reason to perform separate analysis is because I think an offensive rebound is far more valuable and must be evaluated in a different way.

Why? If the player who we're analyzing wasn't on the court, in theory a defensive rebound is far more likely to result from a missed shot than an offensive rebound.

Photograph: Jeff Findley in iwuhoops.com/

On average, the ratio of offensive boards is about 3:7. If we assume that everyone contributes equally, the player we're analyzing contributes .6 offensive boards, so the rest of his team would get 2.4 offensive boards per 10 missed shots (close enough to 25%).

Thus, an offensive board means .75 more possessions than expected, a defensive board .25 more.

A selected excerpt from the discussions at the eBA Annual Analysis System Clinic Chat about this topic "Basketball Rebounds".

Friday Press Clippings:
The Art and Science of NBA Defense

From 20 Second Timeout
By David Friedman
Download source here: ' The Art and Science of NBA Defense ' by David Friedman

"... Johnny Bach, Phil Jackson's "defensive coordinator" on the Chicago Bulls' first three championship teams, has seen a lot of changes during his more than 50 years of college and professional coaching: "I think scouting is far better than it ever was...we have it on DVD and we have it edited.

I don't think players had as much information as they have now and I think it contributes to playing the scorers better--deciding who are the scorers and really concentrating on how we're going to push them out a little further (away from their favorite areas).

You have so much information available--the statistics alone, then you have the pictorial review that I can produce to a team. What we call 'criticals'--out of bounds plays, what they do after a timeout, what they do when the score's tied, what's the last shot of the quarter--all these things are broken down now." ... "

"... Using speed and passing to relentlessly attack the defense is not a new idea. In the 1950s and 1960s the Boston Celtics won championships with a wide open style that encouraged players to adjust to situations on the fly.

Hall of Fame point guard Bob Cousy, the maestro conductor of the Celtic fast break, declares, "Basketball is more of a free-flowing game of instinct and reaction to an action...Normally people associate basketball players with height, but in my judgment speed and quickness are what separate the men from the boys...

Every time down the floor is a different situation. Your action is a reaction to what the defender is doing. We (the Celtics) relied primarily on transition rather than set plays. There was always constant movement. We were always trying to impose the maximum pressure on the opponent whether it was on defense or offense." ..."

Basketball Statistics Analysis Referred Concepts:
Analyzing the Home Performance Advantage or 'ceiling effect'

Meanwhile field goals and three point shots may vary in location and defensive pressure, a free throw is the same during games as it is in practice every time.

Therefore, can we speak about a relation between free throws and home performance advantage ?

It is possible that every time a college basketball player shoots a free throw before a crowd, social facilitation occurs and that the benefits of being at home or being a better shooting team are held by a home advantage effect.

If this effect occurs, it is possible that poor free throw shooters, for whom the area is non-dominant, may benefit from a home performance advantage or the 'ceiling effect'.

It is possible that free throw shooting is an influential undertaking in the home performance advantage. Although field goals and three point shots be subject to change in accordance with location and defensive pressure, a free throw is the same during games as it is in practice every time.

According to our statistics analysis, in opposition, field goal shooting looks to be an undertaking that can be influential or non-influential while three point shooting looks largely a non-influential undertaking.

The instance of change in shooting aptitude was small in a relative manner. As an option, some players who shows special good skills at three point shooting may reveal an alike benefit. This can be addressed in future studies from the eBA Basketball Statistics System.

Basketball Registering Stats Referred Questions:
Held Ball or Traveling Turnover

"... A1 jumps and shoots, but B1 taps the ball and is still in A1 ones hand.

A1 returns with ball that never left his hand. Is this jump ball, traveling, or a block shoot? B1 just barely tap the ball in the shooters hand.

And what is the statistician rule according to the eBA Basketball Statistics Analysis System ? ..."

Photograph xmldatabases.org

eBA Basketball Statistics Registration:
If B1 prevents A1 from releasing the ball, it's a held ball, with the statistical register according the alternating possession rule.

If A1 chooses not to release the ball, it's traveling, registering a forced turnover against A1 and a forced steal in favour to B1

See in our forum the 'traveling turnover' topics and the exposition "Basketball FGA Statistical Analysis" at eBA ONLINE.

Basketball Statistician's Digest:
April 2010 eBA sketball Statistics Case Study Conclusion

Different Situations in a Basketball Shot... Case Study

"... As the shot clock is about to expire, A1 shoots and the ball without doubt is in flight before the buzzer.

• case a) The shot-clock buzzer sounds while the ball is in the air and the ball strikes the basket ring or enters the basket.
• case b) The shot-clock buzzer sounds while the ball is in the air, the ball fails to hit the ring, and A2 rebounds.
• case c) The shot-clock buzzer sounds while the ball is in the air, the ball fails to hit the ring, and B3 rebounds at the right wing of the court.
• case d) The ball fails to hit the ring and the shotclock buzzer sounds as B3 rebounds.
• case e) The ball hits the ring and the shot-clock buzzer sounds as B3 rebounds over A4.

What is the statistical registration according to the eBA Basketball Statistics Analysis System in each one of the given situations, including the type of the registration ( close, long, disputed or undisputed rebound, etc...) ... ?"

Conclusion:
eBA System Statistics Fundamentals:
A player should not be charged for a shot from the field influenced by the illegal actions of himself or herself, or any teammates or opponents unless the shot results in a FGM.

Photograph from popdose.com

eBA Basketball Statistical Registration:
In all cases, no turnover is charged !

• In (a) the horn is ignored. Charge A1 with a FGA and, if the shot is good, credit A1 with a FGM;

• in (b), (c) and (d) the officials call the violation and Team B is awarded the ball for a throwin. Charge A1 with a FGA and credit Team B with a dead-ball rebound;

• in (e) the officials do not call a violation and Team B continues control of the ball. Charge A1 with a FGA and credit B3 with a disputed rebound.

This Case Study was presented as every 10th. day of each month, on April 10th, 2010 in our eBA Portal: were sent 246 answers, 198 partial answers and 39 totally correct, that's means including all the options, registrations and qualifications.

Sunday's Reflexions on Basketball Statistics:
Free Throw Shooting Influence on End Result

In what manner free throw shooting have an influence on the end result of games ?

Let's take to be true, for example, that both teams had converted all of their free throws, or the losing team convert all of its free throws and the winning team convert the same number of free throws.

How all these data is performed statistically to the end ?

Here are some numbers from the archives of the eBA Basketball Statistics Analysis System:

1.- The average number of free throws attempted in a game is about 25 per game.

2.- The shooting average is about 75% efficiency.

Photograph: Basketball_China

3.- That implies as a possibility that a 1% upward would make an actual deviation in FTM once every 4 games (see 1.-: teams shoot 25 FTA per game), translated in only one point every four games.

4.- Teams win by one point 5% of the total of games played.

5.- That 1% upward in FT% would tell us that 25% of these 1-point wins would instead go to overtime.

6.- And finally, to go on with discussion, that 1% FT% upward give us a win on 5% * 25% * 50% = 0.6% of the team's games, or 0.5 current games: that's means one additional win every two seasons.

Friday Press Clippings:
Analyzing the Votes for the All-Defensive Team and the All-NBA Team

From 20 Second Timeout
By David Friedman
Download source here: ' Analyzing the Votes for the All-Defensive Team and the All-NBA Team ' by David Friedman

"... Most of the NBA's annual awards are selected by a panel of media members but the All-Defensive Team is chosen by the league's head coaches, who are not permitted to vote for members of their own teams. ... "

"... It is also odd that the center position received 124 First Team votes out of 122 ballots cast. If the media is trying to create some kind of "higher justice" by voting for the best players without regard to position then the league should either eliminate positional designations on the All-NBA Team or else insist that the voters stick to the official guidelines and vote for players at the positions that they actually play; unless the NBA officially gets rid of positional designations on the All-NBA Team I think that the squad should include the top three centers, even if this means that some forwards or guards who are "better" players are left off of the team. ..."

"... The media chose Brandon Roy and Joe Johnson as Third Team guards, while I picked Roy and Chauncey Billups, who only received 24 points in the media voting despite averaging a career-high 19.5 ppg; I never bought the myth that Billups single-handedly "changed the culture" in Denver (the Nuggets were a 50 win team before he arrived and they benefited last year from the addition of some healthy bigs plus some down seasons by several Western teams) but I do think that he deserved All-NBA Third Team honors this season.

That said, Johnson is a worthy choice as well, though some of the voters may want a recount in light of his lack of production in recent playoff games. ..."

Basketball Statistics Analysis Referred Concepts:
Analyzing the Weighted Standard Deviation

Performing this calculation we must not mistake precision with accuracy. Nonparametric elements like percentiles make no hypothesis that is taken for granted about the shape of the distribution: they are more cautious measures and much less likely to return errors at the the highest degrees.
If you're searching leaders in a category, I recommend you to always use nonparametric measures with a common plan with parametric measure, merely to be sure there are no outliers into your results.

The weighted standard deviation doesn't succeed in seizing the unfairness between two players with the same rates in different quantities of playing time. Same rate is as if: that rate and no more. What it would succeed in catching is a significant change between the width of the distributions, having an effect upon the standard scores. The differences between player rates would be involved, but not if they have the same rate.


When analyzing numbers with measures that aren't well fully apprehended, I give preference to study at the numbers from multiple angles. In this case which you propose at your question, I would perform the computations using

1. Percentiles
2. Standard deviation
3. Weighted Standard deviation by minutes
4. Weighted Standard deviation by square root (minutes per game)

and examine and note the similarities or differences of them. There shouldn't be much significant change, but it would be holding the attention if there was.
