Khudobin, Bobkov, Pechurskiy are pretty sure shots. Proskuryakov looked good at times, but I heard he might have some disease threatening his career and got dumped by Magnitogorsk(pretty raw). Alistratov I don't see anywhere near the top. But he's still young and could develop.
On Bobkov: he has this special thing. He plays great in important games, which is maybe the most important virtue for a goaltender. His WJC record is amazing. And this year's finals were too. To come of the bench and stop everything in a final like that is another example of his ability to be at his best when needed most.
