A metric that estimates how many points an individual player produces per 100 team possessions. This concept is also used to rate a team's offensive production per 100 possessions.
Offensive Rating uses the same theoretical base as Defensive Rating, but looks at points produced as opposed to points allowed. This statistic actually started out as a way to determine how many points a team scored per 100 possessions.
However, the originator of this formula, Dean Oliver, moved this concept to the player level as a way to estimate a player's offensive contribution to his team. Oliver details the player-specific version of Offensive Rating, along with many other key statistical concepts, in his landmark 2003 book Basketball on Paper.
