Shot differential is a telling NHL statistic, it looks at a team's average shots for versus the average shots allowed on a per game basis. The idea is simple, a team with a positive differential gets more shots on net while allowing fewer shots against. The result is proportionately more scoring chances than their opponent. Teams with a negative differential and a good winning percentage are forced to rely on their goaltending more to win games.
