Might I refer you to prediction number 5 in this post from just about a month ago:
I was hoping it wouldn't happen, but with the shortened schedule, the exact scenario I figured would happen played out - one of the goalies (Monster in this case) sits for an extended period of time, he comes in and plays a few games and gets a W. Didn't think it would happen in his first NHL game, but the kid looks legit. I love it. So nice to have a 3rd NHL goalie in the stable. A luxury we haven't had in a while.
Way to go Petr. Congrats on your first W. Here's to many, many more!
