Klimmovich has some time to figure it out. No doubt that he needs to change his play style to be an NHL regular but he has all the tools to play a different way. If they can mold him into more of a power forward he could carve out a career. So far though, he's not that physical and would need to learn how to play in front of the net a bit better.
With his current play style, I think that he isn't really that much of an NHL prospect. But with a new coach, new system, maybe he can change his style/develop to fit an NHL niche.
