Statistician's Digest: About the Top 20 Overall AS/TO 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;
- eBA 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.
