The hockey analytics community has developed a number of advanced stats that help us to better understand the game we love in recent years. One statistic, GAR or goals above replacement, is a measure that essentially indicates how valuable a player is to a team in terms of goals. It is similar to baseball's wins above replacement statistic, but it replaces wins with goals. It is also used for goalies even though they are not typically the ones scoring goals. Rather in their case, it is effectively goals saved above expected by a replacement level goaltender. This year, Hellebuyck entered the top-five on this list, although we only have data that goes back to 2007 so the greatest goaltenders before that are not on the list.
Looking at just this season, Hellebuyck has once again been in peak form. If we look at just 5 on 5 statistics, the majority of the ice time played in the NHL, Hellebuyck leads all goalies in goals saved above expected by a large margin. So large even, that he is effectively in a class of his own.
