I wish I had found this site sooner.
This info isn’t current but it’s interesting none the less.
The guy that runs the site, Basketball-Statistics.com, stopped updating it at the end of January (he’s a Harvard student and the rumor is that he was hired by some pro team and was committing his time to them not the site), but I know the info is of interest to some even though it isn’t up-to-date.
First the plus minus numbers for individuals.
Now an explanation:
These plus/minus numbers are what’s called on/off numbers. It’s a comparison of what the team does while the player is on the court vs what it does when he is off the court projected out to a normal 66.5 possession game. So if a players Net Offensive Plus Minus is 10.0, like Andrew Jones is (the best on the team), it means that the team averages 10 more ppg when he is on the floor than when he is off. Positive numbers are good.
Conversely, if a players Net Defensive Plus Minus is -6.9, like Talor Battle’s is (the best on the team), it means that the team averages giving up 6.9 fewer ppg when he is on the floor than when he is off. Negative numbers are good in this case.
The Net Overall Plus Minus is simply the Defensive Plus Minus subtracted from the Offensive Plus Minus.
The Total Plus Minus is what people normally thing of when they talk about plus minus numbers. It’s the difference between the points scored while the player is on the court minus the points scored by the opponent.
The final column Possessions On Court is simply the number of possessions that the player was on the court for.
