GmScGame Score
Game Score is John Hollinger’s single-number summary of a player’s value in one game — scaled like points.
Formula
GmSc = PTS + 0.4×FGM − 0.7×FGA − 0.4×(FTA−FTM) + 0.7×OREB + 0.3×DREB + STL + 0.7×AST + 0.7×BLK − 0.4×PF − TOExample
A player with 28 PTS, 9 FGM on 18 FGA, 4-of-6 FT, 2 OREB, 6 DREB, 2 STL, 5 AST, 1 BLK, 3 PF, 2 TO: 28 + 3.6 − 12.6 − 0.8 + 1.4 + 1.8 + 2 + 3.5 + 0.7 − 1.2 − 2 = 24.4.
Why it matters
Game Score finds the headline performances of a season in one number — perfect for "Player of the Week" callouts on a league page.
In depth
Game Score weights the box-score line into a single number on a points-like scale. A Game Score of 10 is a solid game; 20 is a great game; 40 is historic. It is a quick read, not a deep model.
Useful for highlighting standout single performances on the public league page.
