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:

Offensive Team Rating = \frac{Players\ Points}{\tfrac{1}{5}\text{ of possessions}} \times OAPOW

• \left(\frac{FTM}{Times\ Fouled} \times FT%\right)
• (Total\ FG%)
• (Opponents\ Differential)

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

For players, the formula is:

Offensive Production Rating = \frac{Points Produced}{Individual Possessions} \times OAPOW \times PPG + \frac{FTM}{FT} \times 3pt% + FG%

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.
