I hate to be a party-pooper, but that just looks stupid to me.
Not the Bertuzzi punch, but the way it appears to be an accepted part of the game.
The way the officials stand back and watch.
The way the crowd cheer every punch.
The way the players are punching other players who have helmets on.
But who can stop it? There are so many influences, it would take a strong sporting body to stop it completely.
