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:

$$OffensiveTeamRating=\frac{PlayersPoints}{\frac{1}{5}\text{ of possessions}}\times OAPOW+(\frac{FTM}{TimesFouled}\times FT\mathrm{\%})+(TotalFG\mathrm{\%})+(OpponentsDifferential)$$

This stat can't be influenced by the defense of a player's teammates.

For players, the formula is:

$$OffensiveProductionRating=\frac{PointsProduced}{IndividualPossessions}\times OAPOW\times PPG+\frac{FTM}{FT}\times 3pt\mathrm{\%}+FG\mathrm{\%}$$

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.

The all-time leader for offensive rating (minimum 15,000 minutes played) is Jarrett Allen with a 130.1 rating.
