Really? Not sure which games you watched but he was only on the ice for 2 goals against all tournament. The first, against Russia, his partner, Markus Phillips gets walked, Bouchard is in the right position and Dipietro gets beat on a cross body shot that's hard to save. Did everything right there. On the second, the first Finland goal, again he's in the right spot, blocking any passes, His D partner, Ty Smith is weak in the corner and gets beat, forcing the forward to leave his position, who makes a bad play diving for a poke check. Again Bouchard is in the right spot, blocking any passing plays and Dipietro doesn't track the puck well here and again gets beat by a cross body shot.
So, only on the ice for 2 GA all tourney, neither of which are on him, playing against all the other team's top players.
He was far and away Canada's best D man.
None of this is on any D or goalie for Canada. You're not going to be Finland or Russia scoring 1 goal.
Canada's power play was pretty bad, and i think a big part of it was that the forwards didn't really use the D, and everyone stood still on the perimeter. Really i think that was their problem all tourney, no one went to the dirty areas to score, and Canada was pretty easy to defend against. Against Russia especially, although they got 31 shots, I wouldn't say they had many scoring chances. In TSN's highlight package they pretty much had all the scoring chances since they were so few.
