What is GSAx in hockey?
How many goals a goalie saved compared with an average goalie facing the same shots. We add up what every shot he faced was worth, then take away the goals he actually let in. It counts every situation. Each season’s shot values are scaled so the league’s add up to its actual goals, so average means that season’s average (until a season has 1,000 goals, the season before’s).
GSAx · Goals saved vs average
