Varlamov is seemingly always injured, and he's inconsistent even when healthy. I think we can do better.
Essentially you'd be giving up a second round pick for a chance to see if this guy can be the real deal. If he isnt, then he leaves for the KHL and you go sign someone in the summer of 2012. I think it's worth the risk.
As for WSH, his agent saying he might go to the KHL hurts his trade value. I don't think they'd get more than a 2nd rounder for him.
