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 (field goals, free throws, plus partial credit for assists), missed field goals and free throws that the defense rebounds, and turnovers.
Leaders The all-time leader for offensive rating (minimum 15,000 minutes played) is Jarrett Allen with a 130.48 rating.). Kevon Looney's 147.40 offensive rating in 2022–2023 is the single-season record. Tyson Chandler has led the league in offensive rating a record four times. Brad Davis, Reggie Miller, Dwight Powell, and John Stockton each led the league three times. Charles Barkley, Adrian Dantley, Cedric Maxwell, and Ivica Zubac each led the league two times.
