Frequently asked questions

What's a good offensive rating in the NBA?

In the modern NBA (2023-24), league average ORtg is around 115-117. Top offences post 120+. Below 110 is poor. The scale has inflated significantly since the 1990s due to rule changes favouring offence.

Why use ratings per 100 possessions instead of per game?

Teams play at different paces, so a team that runs more possessions per game will naturally score and allow more points in raw per-game terms — rating stats are standardized per 100 possessions specifically to let you compare offensive and defensive efficiency fairly between a fast-paced team and a slow-paced one.
