Of the goaltenders who have appeared in
more than 10 games, Korpisalo has the sixth-worst save percentage (.884 SV%) and the fourth-worst goals against average (3.70 GAA). The 8-15-0 record is pedestrian but buoyed by the fact that the Senators have given him
goal support of 3.20 goals per 60.
The Finn has the
third-worst goals saved above expected rating (-12.55 GSAx) in the league trailing only Ilya Samsonov and Vitek Vanecek. Evolving-Hockey’s ‘Goals Above Replacement’ (GAR) and ‘Wins Above Replacement’ (WAR) statistical models try to measure a player's value by combining his performance into one encompassing number. While not perfect, these metrics attempt to determine how much more valuable a player is to a replacement-level player at his same position. By both metrics, Korpisalo has been the least valuable player in the league at his position this season.
