Thanks for the clarification fnordius
the plus minus part of the stat shows that the team overall plays slightly better without Moore than with him. However, I think his system favors offensive "super star" players (even thought it "should" be an adjusted number) due to points scored vs points against (over time). The on-off court numbers "should" reflect how important a player is to a team. It's an interesting system, but I don't see why Bruce Bowen is near the bottom and Ben Wallace is at -3 (unless he's having that bad of a season with CHI of this year). There would be an extremely high correlation between ppg and Roland rating. Premier defenders should have positive impacts on their teams since defense wins championships. Like most rating systems, I think Roland's system favors offense over role players.
