Substantially worse? Since when is .001 sv% substantial??
Comrie AHL career stats:
207 GP, .911 sv%, 2.82 GAA, 90-92-21-10
NHL: 9 GP, .873 sv%, 4.07 GAA, 3-5-0
Berdin:
95 GP, .910 SV%, 2.76 GAA, 45-40-8-4
And last year was way below Berdin's previous performance (.897) - I'd say a bit skewed by playing a TONNE of back to backs and then long breaks due to the whacky AHL schedule. Berdin was ridden HARD last season...
Unless you're referring to just last season for Comrie, since he came in at the very end of the year and got .947 in 4 games, once the Moose were rolling (they started the year terribly...). That's an incredibly small sample size...
Recency bias??
