It's possible, I just think the playoffs is a small sample size overall, plus he was dealing with the eye injury somewhat still he suffered in Round 1. His numbers from regular season last year were actually extremely solid, and much better than Grubauer's the year before when you account for the team in front of them. He put up good numbers in Arizona, as well. Biggest concern for me is injury concern, and he's actually already 32. But his salary is cheaper last couple years of the deal to make it easier to potentially trade him by then.
I just don't see Samonov or VV ever looking like a better option, at all. VV is kinda what he is, a NHL backup. Samsonov maybe figures it all out? But he has had a lot of chances to do so and couldn't. It was time to move on one way or the other.
