Turn a goalie's box score into the numbers that matter: goals-against average, save percentage, and a win–loss record — with a read on how good they actually are.
GAA = goals against × 60 ÷ minutes played (so a full 60-minute game is one unit). Save % = saves ÷ shots. A save percentage above .915 is elite, .900–.915 is good, below .890 is struggling. A GAA under 2.5 is strong.
