I'll admit the only time I have seen Berra play is in this years IIHF Championship.
What I've noticed so far is that he plays a big mans game. His angles and positioning are sound and he always seems to be in the right spot for that first save. His rebound control is good when he is not over aggressive, and when he does give up a bad rebound he seems to be a little slow when getting back into position or making the second desperation save.
He also seems to play a little deep in his net. That being said he is a Euro goalie playing on the big ice so being deeper in the net is to be expected. I'd like to see if he can get maybe 5-8 inches further out once he makes the jump to the smaller ice.
Also one thing to note is that one of the major reasons European goalies are succeeding in the NHL today is BECAUSE they are taught to play deeper in the net. This makes a goalie focus more on reactions and less on just blocking the puck in the butterfly stance. Quebec style goaltending is outdated and if Canada ever wants to regain its goalie dominance we have a lot of work to do. Unfortunantly, with the smaller ice, things happen faster so goalies end up relying much more on their positioning. Condition a kid from an early age to play that way and we end up with our current goaltending situation. Plainly said, the big ice is better for developing a goalies reactions, and I'm not convinced Canada will ever regain it's goalie dominance.
