How do many NBA coaches quickly evaluate a player's game performance? They check his efficiency.
NBA.com evaluates all players based on the efficiency formula: ((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers)).
For example, compare the following stat lines:
MIN
FGM-A
FTM-A
REB
AST
STL
BS
TO
PTS
Player A
43
5-22
7-9

Player B

Player A had a better game, right? Not exactly. Player B, who shot 5-8 from the field and committed two turnovers, registered a +20 efficiency total while Player A, who shot 5-22 from the field and committed four turnovers, posted a +11.
