I think he'll be a good hockey player, but won't live up to the lofty expectations of him that's being put on here. He had a very hot start (20 points in 16 games) and has fizzled hard since, but is picking it up nicely in the playoffs. Maybe the super long break the KHL had for the Olympics (I know he played in the Olympics, but he had lots of off time) helped him get rested, but if he fizzled before because of being worn out it's hard to imagine competing in the KHL playoffs, flying to NA, and immediately competing in the NHL playoffs won't wear him down heavily.
He'll be good, I'd just temper my expectations for these playoffs.
