Game Score is a player evaluation metric which can be considered John Hollinger‘s simple and linear version of the Player Efficiency Rating.
Game Score Formula=(Points)+0.4*(Field Goals Made)+0.7*(Offensive Rebounds)+0.3*(Defensive rebounds)+(Steals)+0.7*(Assists)+0.7*(Blocked Shots)- 0.7*(Field Goal Attempts)-0.4*(Free Throws Missed) – 0.4*(Personal Fouls)-(Turnovers)
Game Score does not make any adjustments like PER does for team pace. It simply adds and subtracts the box score statistics, according to the various weights Hollinger has chosen.
