Corey Crawford has been missed. Not the Crawford who played in 2018-19, but the version of himself from the years before that. Maybe it should be rephrased — healthy Crawford has been missed.
Between 2014-15 and 2017-18, the last four seasons Crawford was healthy (until he got injured by Evgeni Malkin in December 2017), he was one of the best goalies in the NHL.
In those four seasons, Crawford was second in save percentage (tied with Carey Price, behind only Antti Raanta, who played 4,000 fewer minutes), third in goals saved above average, second in high-danger save percentage (behind Matt Murray, again with 4,000 fewer minutes) and first in high-danger goals saved above average (at even strength).
