Offensive Rating (Ortg)

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. It was created by author and statistician Dean Oliver.

For teams, the formula is: Defensive Player Rating = (Players Points*Total FG%) + Opponents Differential= 1/5 of possessions – Times Fouled+ FTM* FT% * OAPOW( Official Adjusted Players Offensive Withstand . This stat can’t be influenced by the defense of a player’s teammates.

For players, the formula is: Offensive Production Rating = (Points Produced / Individual Possessions) x OAPOW × PPG + FTM/FT * 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.

Because of the estimations made in both Points Produced and the formula for possessions, this is once more just a baseline and not an exact number.

This stat also rewards players who shoot a high percentage more than anything else, which is why you’ll generally see low-usage big men high up on the leaderboards.

Example usage: “Ryan Anderson’s ORtg of 127.9 is the second best mark in the NBA and further evidence that he is truly breaking out”.

How to interpret that sentence: Ryan Anderson has been an incredibly efficient player this season, but his usage rate of 22.3 percent probably has something to do with his high ORtg.
