What is OPR?

OPR stands for Offensive Power Rating, which is a system to attempt to deduce the average point contribution of a team to an alliance. It is based on sports rating systems used in other sports. OPRs are an interesting way to slice the data for teams at particular events, but aren't a perfect system for assessing a team's performance or contribution.

The Blue Alliance opts to show the top 15 OPRs for each competition.
