Yes, I do, especially based on a 5 or so game sample of infrequent play in the final month of the season. If it was Rask getting that playing schedule you wouldn't want me tryiing to use that as any kind of qualitative judgement. I know because we've had this conversation.
Sure, Rask outplays Thomas. Rask this year outplays everyone. That doesn't mean that Thomas is a bad goaltender, or that he couldn't win a game if he was called on to do so. In his own right, Tim Thomas is a very respectable goaltender, and when he was in for the B's he carried his weight. Yes, even this year.
The 4 goaltenders immediately surrounding Tim Thomas in the final SV% rankings this year (the two just above, and the two just below) were Martin Brodeur, Johan Hedberg, Chris Mason, and Roberto Luongo. In GAA, it's Jonathan Quick, Thomas Vokoun, Brian Elliot, and aforementioned Luongo. Yes, he slightly outplayed Roberto Luongo in both SV% and GAA.
That's pretty sweet company all things considered. Sure he isn't Tuuka the Invincible, but could he win you a game? The guys around him sure could, and he sure has in the past, I see no reason at all not to answer that question with a "Heck yes."
Take the emotionalism out of it and actually look at the numbers, this guy's done a good job. Yes, even this year. He got outplayed by a guy with a puncher's chance to be in the company of Patrick Roy when he retires, ultimately that's out of his control. What he can control though, is his performance on the ice, and he did quite a fine job there, thank you.
