I tried to allude to this, but it wasn't very clear: I adjusted so that the average OPM on the floor for a random possession is 0. Different plus/minus stats have different conceptions of what the stat is in reference to: some have a target value for a "replacement player", some want an average of 0, some want an average of 0 across different positions or seasons, etc. This prompts a couple different questions that I'd be interested in hearing thoughts on. Sum up the raw BPMs for the team (weighted by % of minutes played) and compare this to the team adjusted efficiency per 100 possessions. There's obviously a big difference between being able to switch onto multiple positions and doingit well, but Wood hasthe foot speed to stay in front of guards and the length to contest shots out on the perimeter.
