Rebounding is interesting. Create a minutes weight for this estimated BPM. Calculate the players estimated position and offensive role, using the entire seasons worth of data. In order to create a box-score-based player evaluation metric, some basis for the weights given to each statistic must be chosen. He ranked around the league average in scoring efficiency in transition (50thpercentile)but was among the league leadersinboth spot-up(86th percentile) and pick-and-roll(95th percentile) efficiency.

It doesnt always work, and the Nuggets occasionally give up an open dunk or three because of it, but largely, the scheme has worked because of what Jokic can do while on the perimeter. This is particularly an issue for elite defenders where BPM simply does not recognize them from their box score statistics. The Houston Rockets are excellent at this, finding ways to manipulate the defense to create as many threes, layups, and free throws as possible. Offensive output is probably less additive than defense, when you combine the effects of players on a team. This prompts a couple different questions that I'd be interested in hearing thoughts on. Such critical components of defense as positioning, communication, and the other factors that make Kevin Garnett and Tim Duncan elite on defense can't be captured, unfortunately. Easily Curry.
