Friday Press Clippings: Do players "steal" rebounding opportunities ?

Friday Press Clippings:
Do players "steal" rebounding opportunities from teammates ?

"... In my previous post on rebounding, I promised to review some of the evidence supporting the "diminishing returns" hypothesis.

That's the theory that, in general, a player's individual rebound totals are not mostly a product of his own ability to snare rebounds, but, rather, predominantly because of his positioning on the court, or the role he is assigned on his team. ..."

"... Every extra rebound by the center results in 0.61 fewer rebounds by
teammates. ... "

"... That means that only 39 percent of center rebounds are "real", in the sense that the other team would have got them if not for the center's efforts.

If a center is (say) 20 rebounds above average for the season, then, on average, you should estimate that 12 of those rebounds would have been grabbed by a teammate anyway. ..."

Even the longest misses produce an average rebound distance that is only eight feet from the rim — not exactly a remote location. Part of this has to do with physics, part has to do with player spacing. Long-range shots generally occur when players are more spread out and there are fewer potential rebounders near the basket. <br />

"... The variance in team rebounds per game is LESS than the variance in rebounds per game by the center
alone ! ..."

"... Every additional rebound taken by the point guard reduces the rest of the team's rebound total by ... almost exactly one rebound: .96, to be exact. ..."

"... Taken at face value, that means that 24 out of 25 times, when a point guard gets a rebound, it's because the rest of the team deliberately leaves it for him! ..."

About the Basketball 'Assist-Turnover Ratio'
& the Basketball Training Video in our Monday's Reflexions on Basketball Statistics

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

Basketball Statistician's Sunday's Reflexions
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);

Under the defensive pression of Bryant Mbamalu, freshman guard Denzel Valentine turns the ball over during the game against Louisiana-Lafayette Ragin' Cajuns on Nov. 25, 2012, at Breslin Center. The Spartans beat the Ragin’ Cajuns 60-63. Photograph by Natalie Kolb / The State News

 • 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 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:

Forget passing, which player is the best decision maker?3 In this image, Leonard’s shot probability is tied for the most likely outcome, even though by expected possession value it is his worst option; passing to anyone would be better. And these numbers can be tailored to individual players! With substantial sample sizes for individual players over the course of thousands of possessions, we do not have to settle for 'Shooters make X percent of open corner threes', we can specify that 'Player Y makes Z percent of open corner threes'. Which point guard best understands his teammates’ strengths and weaknesses, the differences between the starters and the subs, etc? Which big man has the most added value when getting the ball at the post?  <br />

Basketball: Pau Gasol - Running Hook - Signature Moves

Work your defender to get him out of position and finish ice-cold with the unblockable running hook shot.

1. Post up Establish contact with the defender in your back. Before you receive the pass make sure that you are in a low and powerful position to keep your balance.

2. Fake baseline Spin to the right to fake out your defender. When he shifts, youve got yourself some space to move.

3. Attack middle Now that you have your defender out of the way, turn round and attack the basket from the centre.

4. Running hook As you approach the basket, use your left arm and shoulder to protect the ball from any block attempts. Then as you take the shot; use your fingertips for extra control and shoot smoothly over your defender into the basket.

Basketball Block Shot Analysis & Statistics Tracking:
With or Without Ball Control is the Question!

Basketball Block Shot Analysis & Statistics Tracking:
With or Without Ball Control is the Question!

The answer was:
A1 goes up for a shot under the basket and the defensive player B2 knocks the ball in the hands of the shooter while they are both in the air, and there is no case of foul. A1 then let the ball fall to the ground before landing back on the court, gathers the ball up and makes a basket.

What is the call for the game and the statistical tracking in case of turnover?

Celtics small forward Paul Pierce has his shot blocked by Charlotte Bobcats power forward Tyrus Thomas during their NBA basketball game in Charlotte, North Carolina. Photo: REUTERS/Chris Keane

By definition (see our eBA Basketball Statistics Analysis Encyclopedia ) a blocked shot occurs when a defensive player successfully and legally deflects a shot from an offensive player by touching and rejecting the ball on its way to the basket, and before it has reached its highest point, in order to prevent from a field goal.

In order to be a legal action, the  block must occur while the shot is travelling upward. It it is heading downward when the defender hits it, it is ruled a goaltending and counts as a made basket.

We have an altered shot when a blocker changes the shooter shot causing the shooter to miss the basket.

Opponents' field goal percentage vary widely depending on which interior defender is close to the basket. Milwaukee's Larry Sanders is one of the most effective interior defenders in the league: opponents struggle to score when he is near the basket. This not the case with Boston Celtics' David Lee: when he is close to the basket, opponents score at very high efficiencies. (Click on the picture to read the full article by Adam E. Gallagher from  Tropics of Meta). In this Image: by Adam E. Gallagher from  Tropics of Meta presented by eBA Basketball Statistics Analysis Group.

If the ball is knocked out of the offensive players hands while they are in mid air, then they regain control once they have landed, this is legal.

If the ball is forced out during the time that the player is in the air, the player regains control (while in the air) and lands, it is a travel.
eBA Basketball Statistical Tracking=
Forced Turnover

If the offensive player returns to the floor, holding the ball, and the ball has never left his hands, one of two things are possible:

1) if the defensive player has only one hand on the ball, it is a travel against the offensive player.
eBA Basketball Statistical Tracking=
Forced Turnover.


2) if the defensive player has both hands on the ball it is a jump ball which will be resolved according with the alternate possession rule

Basketball Statistics Referred Concepts:
Points per Field Goal Attempt Formula: Concept & Application

Basketball Statistics Referred Concepts:
Points per Field Goal Attempt Formula: Concept & Application

Basketball Statistics Analysis Referred Concepts
In order to measure how strictly correctly a player or team is shooting we need statistics, and if possible a creative analysis of those basketball statistics.

Statisticians most often use the field goal percentage ( FG% ) to do it, but the added bonus of the three-point shot, for instance, isn't reflected in field goal percentage, and the ability to get to the free-throw line (where the points come much easier) is ignored as well.

"Points per Shot Attempt" (PSA): It's a stat designed to reflect the basics of good shooting: getting the greatest number of points from the fewest number of attempts.

this chart provides a useful baseline that we can use to evaluate individual shooting performances. By overlaying players’ shot constellations, we can estimate the expected total number of points that an average NBA shooter would produce, based on where he took his shots; then we can compare a particular player’s actual yield against it.

By overlaying players’ shot constellations, we can estimate the expected total number of points that an average NBA shooter would produce, based on where he took his shots; then we can compare a particular player’s actual yield against it. (Click on the image to continue reading the article!)

Points per shot attempt is simply points divided by shot attempts . Figuring shot attempts is like this: Add field goal attempts plus "Up to the Line" (for 2 or 3 free-throws).

In case of analysis of another team and if you can't know how many times the player or the team reached the line, use (0.4 * FTA) instead.

PSA = Points / (Up to the Line + FGA)

Last years NBA league PSA average was something around 1.039 points per shot attempt, so by averaging, by example, 1.133 points per attempt, an average team gains a full point with every ten shots.

Points per Field Goal Attempt Formula

PSA is just as handy for rating individual players as it is for teams. Occasionally a player will break into the top ten who shoots nothing but dunks, but mostly it's the long shooters who are at the top of an individual PSA list.

This formula, with another fields formulas, are integrated in the 2nd. exposition of the Basketball Statistics Registration eBA Course: "Statistics Formulas Revision", at eBA ANNUAL CLINICS ONLINE.

Plus Minus Rating ~ Definition & Applicability

UNC's Tar Heels have a history of deep benches and using all their players, here Harrison Barnes, in their drive to win NCAA men's basketball championships. This is the team and his Head Coach Roy Williamns, that invented the second five. The team that can substitute players as interchangeable commodities rather than key ingredients to a championship run. The team that had removed its starting five for several minutes during a debacle at Georgia Tech, only to right itself and beat Duke and win the ACC regular season.

Derrick Rose's Basketball Teardrop by eBAsketball

Derrick Rose's Basketball Teardrop

Tony Parker was one of the first to use the “teardrop” in the NBA as a main weapon against bigger defenders patrolling the paint, but Bulls guard Derrick Rose has taken it to a whole new level and does it better than anyone in the Association. He uses his great quickness to set up his defender.

Once Rose has his opponent on his heels, he utilizes his lightning-quick crossover dribble, stops on a dime, springs up off both feet, and floats a shot with his strong hand.

What makes Rose’s jump stop so tough to defend is the way he can contort his body when he attacks the rim. Because of that threat, his floater is extra tough to anticipate.

Monday's Reflexions on Basketball Statistics:
About the Minutes Played, the Foul Trouble & Fouling Out

Basketball Statistician's Sunday's Reflexions
How to make a statistical calculation of the player's missed playing time ascribable to fouls ?
Is there in the the eBA Basketball Statistics Creative Analysis System some data about the player utilization and substitution set of rules in the foul trouble case ? That means to say, when they are sent to the bench and after which foul number ?

To calculate missed playing time ascribable to fouls, we must base our analysis in the following assumptions about player usage and substitution patterns:

In FIBA & NBA:
No change when a player commits his first foul.
Committing his second a player foul would be replaced and have to wait at the bench until the half of the second quarter.
A player committing his third foul would be replaced and would be a bench player until the third quarter.
With the critical (in FIBA) fourth foul committed a player would be replaced and have to sit until the beginning of the the fourth quarter.
In NBA:
A player committing his fifth foul would have to be out of the game until the half of the fourth quarter.

Photograph: Day Life

Now, how often do players foul out of a game ? When the 4th. FIBA or 5th NBA foul happens ? Which percentage of the players with the 4th. FIBA or 5th NBA foul are fouled out ?

- 49% of the 4th. fouls FIBA or 5th. fouls NBA come with about 3 minutes left in the game: remember to consider, 40 minutes in FIBA and 48 in the NBA !
- 82% of all players who perpetrate a 4th. fouls FIBA or 5th. fouls NBA do not foul out.

This is reasonable from the moment the studies from eBA Basketball Statistics Creative Analysis System demonstrates that even the most players having a tendency to foul lose only a few minutes per game because of their foul trouble. But they play the great majority of their minutes near the danger of fouling out.

The analysis of the different types of Foul Trouble, are studied in the eBA Basketball Statistics Tracking Clinic.

"Stat Gurus" Forced to Consider Possibility That the "Hot Hand" Exists
by David Friedman ~ in our Friday Press & Video Clippings

"Stat Gurus" Forced to Consider Possibility That the "Hot Hand" Exists
By David Friedman

"Stat Gurus" Forced to Consider Possibility That the "Hot Hand" Exists
by David Friedman

"... "Stat gurus" puff out their chests and declare that their proprietary methods give them a significant edge over "old school" talent evaluators but research shows that tanking does not work precisely because of just how difficult it is for anyone--even a "stat guru" armed with reams of "advanced basketball statistics"--to predict/project future player performance.

Another cherished "stat guru" assumption is that the "hot hand"--also known as being in the "zone"--does not really exist.

Many people who have coached, played or even just watched basketball believe that they can recognize when a player gets "hot"--when he is in an unstoppable "zone"--but "stat gurus" dismiss such ideas. ......"

"... "Stat gurus" cheered when a 1985 study conducted by Thomas Gilovich, Robert Vallone and Amos Tversky indicated that what may look like a "hot hand" is really just a random occurrence.

One major problem with that study, though, is that it did not represent a meaningful sample size. The researchers focused on the shooting statistics of the Philadelphia 76ers because the 76ers were the only NBA team at that time which kept complete shot by shot data.

That is kind of like looking for your lost keys in one small area not because that is where you think that you lost them but because that is the only place where there is enough light to conduct your search. ..."


The data seems to show that successful shots are more likely to follow misses rather than hits. In this image from Jumbo Dumbo Thoughts presented by #eBAStatsGroup #BasketballStatistics Analysis .
Image: Jumbo Dumbo Thoughts



"... The amount of available statistical data has exploded in recent years and, after examining more than 70,000 NBA shots from the 2012-13 season, three Harvard researchers concluded that a player who has made his previous several shots is at least slightly more likely to make his next shot.

Does this study conclusively prove that the "hot hand" exists? Of course not.

The scientific method requires that hypotheses be repeatedly tested; Albert Einstein's Theory of Relativity is perhaps the best known and most successful theory in scientific history but researchers to this day still test Einstein's hypotheses regarding space, time and gravity.

Any "stat guru" who asserts that he has created the definitive player rating system is not practicing science; he is peddling snake oil. ..."

"... When I criticize the flawed reasoning employed by many "stat gurus" and when I point out the inherent limitations of "advanced basketball statistics," some people misinterpret my analysis to mean that I harbor some reflexive biases against using the best possible statistical tools to better understand basketball.

My main point is that "advanced basketball statistics" should not be worshiped as some infallible bastion of truth; "stat gurus" should habitually create testable hypotheses and then see if the best, most comprehensive data that can be gathered supports or refutes those hypotheses.

If Player X supposedly has a "rating" of 33.8 and is supposedly exactly 2.5 rating points better than Player Y, what is the margin of error in that rating system? ..."

"... Ironically, as more data about basketball is collected and analyzed, it is becoming evident that assumptions made by allegedly objective "stat gurus" are not any more trustworthy than assumptions made by supposedly subjective and/or biased observers. ..." Read more ...

About Basketball Steals and Defensive Efficiency and the Defense By The Numbers
and Basketball Actuality News Video in our Thursday's Basketball Statistics Referred Concepts

Basketball Statistics Analysis Referred Concepts:
Basketball Steals and Defensive Efficiency

Basketball Statistics Analysis Referred Concepts
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...

 • ...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.

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.

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.
