Question about possessions calculation in Stats App - Dean Smith or not...
Below is a question we got from a subscriber named Chuck. It’s a question in regards to how possessions are calculated in the stats tracking app.
Email 1 - Question:
I am curious about how your stats application calculates possessions. I have used it the last two years and the points per possession numbers are different than what I calculate by hand.
Thanks,
Chuck
Email 2 - Dennis Haefner's Response:
We use a formula developed by Dean Oliver to calculate possessions. Possessions are field goal attempts + turnovers - offensive rebounds + .4 * free throw attempts. It, of course, is an approximation to actual possessions, but it should be pretty close.
(Here are Basketball Statistics Definitions for more clarifications.)
Email 3 - Chuck's Response:
Thank you. That is what I thought. I think many others use a similar formula. The “problem” is subtracting offensive rebounds. I use Dean Smith’s definition for possessions. When the shot is taken the possession is over and an offensive rebound gives the team another possession. I know a lot of the analytics guys subtract out offensive rebounds – I believe this is one of the main reasons for the belief that they are not important has taken over in the NBA. When one subtracts offensive rebounds possessions are almost always roughly equal so they focus solely on efficiency and wanting to measure it.
Dean Smith on the other hand was a basketball coach focused on winning games. His way can give very large differences in possessions and now there are two ways to win. Be more efficient and/or dominate the number of possessions.
We use possessions, as Dean Smith did, as a better judge of overall rebounding plus hustle on those “50-50” balls. I may be the only one doing it that way but if not you may wish to offer both statistics? If not I’ll just keep calculating it by hand.
Thank you.
Chuck
Email 4 - Jeff Haefner's Response:
That is one way to look at things. Instead of trying to get more possessions than the opponent, I think in terms of trying to get more shots. And use the possessions (always almost equal) to determine your PPP (efficiency -- which is also useful info). This article kinda explains that philosophy. I want to score more points than my opponent. The only way to do that is to take more shots or shoot a high percentage.
9 Stats That Every Serious Basketball Coach Should Track
Basically we are talking about the same thing. Just going about looking at the stats in a different way. Both ways work… as long as it makes sense to the coach evaluating them.
Thanks
