He was terrible against Team Switzerland and but was alright against Team Finland. Like Lapa said, he was invisible. Gotta see him against Team Russia/Canada/USA to actually see if he's sound defensively.
He's been fine. Has he made some mistakes? Sure, but all of Canada doesn't look very good. The moron with the "3-1 Thanks Dumba" quote must be blaming him for taking a "penalty" He was called for tripping, Slovakia dove, or tripped on the blueline. He touched his skate, the guy flopped. Like a lot of young defensemen, pressure him and he is more prone to a mistake. He hasn't been their best player, but he's being trashed when he shouldn't be. Like Jaykay said, it happens every year and especially with Canada fans. WAY too much stock is put into this tourney.
