To me, it boils down to sportsmanship, or lack thereof. There is plenty of time to sulk afterwards. If you lost fair and square, you should at least be grateful for being able to participate. News flash; only one team was going to win, though Russia did get owned...bad.
Think about if it turned out the other way around, with Russia winning & Canada losing the game. Do you honestly think the Canadian players would have left the ice the way team Russia did? Hell no. Poor sportsmanship is it. I've always had a major hate on for Kovalchuk, it just got a little deeper.
It sucks to see the other guy win the game to be crowned champion, but if you gave your all and still lost, congratulate the winner, hold your head up, and go figure out how to get 'em next time. Don't go off the ice like a bunch of spoiled whiny babies because you got stomped. Russia made this more of a story than it needs to be. They have reason to be ashamed.
