Canada has a lot to improve (eliminate turnovers in the middle of the ice because of casual play, soft passes, and too much reaching with their sticks), and yet they win that type of game 80% of time given the shots, possession, and scoring chances. Congrats to the US for capitalizing on a poor finish to the 1st by Canada as that was the difference in the game.
Ice was horrible in Columbus and really mucked the game up, which favored the US style of game. Hopefully it should be better going forward when the tournament shifts to arena's that are better prepared for games in September.
