Offensive rating

Offensive proficiency rating or offensive productive efficiency is a statistic used in basketball to measure either a team's offensive performance or an individual player's efficiency at producing points for the offense by approximating the number of points generated by a team or individual over 100 possessions. It was created by author and statistician Dean Oliver.
For teams, the formula is:
This stat can't be influenced by the defense of a player's teammates.
For players, the formula is:
Points can be produced through field goals, free throws, assists, and offensive rebounds. Individual possessions are the sum of a player's scoring possessions, missed field goals and free throws that the defense rebounds, and turnovers.
The all-time leader for offensive rating is Jarrett Allen with a 130.1 rating.
