John Tavares' missed penalty shot in the 3rd sealed New York's fate.
If you heavily outshoot your opponent, you win about 90% of the time. Okay, I just made that stat up, but you get the idea. Wear down the other team with constant pressure and keep them from attacking your own net and you've got a pretty good shot at winning a hockey game.
They got outshot by twenty-eight shots. Not once did they register a double-digit shot total in a single period, and they only managed four shots in both the first and third periods. And yet they still managed to win, largely thanks to some spectacular goaltending from Ryan Miller down the stretch.
It also doesn't hurt when the opposing goalie allows 20% of the shots he faces to get past him. Looking at you, Evgeni Nabokov.
