It's a tough one.
On one hand, you expect to allow at least 2 goals when you've allowed 39 shots to a team like the Penguins. But that goal was pretty bad. The first one wasn't good either, but it was much more forgivable. Allowing that one after tying the game was pretty brutal.
I thought he played well in this series though, he might have allowed 3 bad goals the whole series. 2 in this game and one last game to Crosby 5 hole, and even that goal wasn't THAT bad.
It reminded me of when Tokarski had to step in for Canadiens a couple years ago in the ECF when Price was injured. It's safe to bet that the odds are that Price would have played better, although he was being lit up in game 1. But Tokarski wasn't nearly the reason they lost. I couldn't expect Vasilevskiy to play much better than he did.
