[BasketBall Geek] Individual Defensive Efficiency Ratings Extracted from Play-by-Play

the_hustler · Nov 3, 2009

A good article for the statisticians on the BBS

I am pleasantly surprised to see Scola on the list

and also.. wth is chuck hayes.. ?

The purpose of the individual defensive efficiency rating is to estimate an individual’s impact on the number of points their team allows per hundred possessions the individual is on the court. As Dean explains in Basketball on Paper, there is a lot of defensive data left to collect that would allow us to better understand defense numerically.

Thanks to the play-by-play, a small fraction of this data is available to us so that we do not have to approximate it from the box score (such as the number of free throws players allow by way of fouls). We still, however, do not have data for key elements of defense, such as:

* Number of field goals defenders force to be missed or allow to be made
* Number of turnovers defenders force the opponent to commit

That's from last season... likely the reason why no Chuck. minimum of 500 defensive possessions.

The other possibility is that they were considering Scola as the center when Chuck and he were both on the floor... skewing the data.
