Remember a team's offensive efficiency?
An individual player can be assessed using a similar measurement. This is a player's Offensive Rating (ORtg).
This stat comes from the mind of Dean Oliver. Oliver defines the offensive rating:
Individual offensive rating is the number of points produced by a player per hundred total individual possessions.
This number tells you how many points a player is likely to score when given an opportunity. It answers the question, how efficient is an individual player?
The tricky part of the calculation is measuring individual possessions. An individual possession is broken down into made shots, missed shots, missed free throws, and turnovers.
Once you identify each component of an individual possession, you can calculate points produced and a player's offensive rating.
ORtg = (Points Produced / Total Possessions) x 100
In the 2015-2016 season, North Carolina's Brice Johnson posted a 127 offensive rating.
What does this mean?
Johnson was extremely efficient when given opportunities to score.
Certain players are more involved in their team's offense than others. If a player has more opportunities to score (individual possessions) this will have an impact on their offensive rating.
For example, North Florida's Aaron Bodager was used on 11.7% of his team's possessions in 2015-2016.
Bodager'soffensive rating was 134.5.
This is why possessions used is important when assessing a player's offensive rating.
