Hockey has had some very ugly incidents, but hockey is not alone in that regard.
Todd Bertuzzi was charged criminally, and he wasn’t the first player so charged. Chris Simon, of the New York Islanders, has been, at times, a very dirty player. In his last incident, he stepped on a Pittsburgh Penguin who had fallen on the ice.
In 1979, the Boston Briuns responded to hecklers at Madison Square Garden and stormed into the stands. An ugly brawl ensued.
But, hey, what about soccer, the world’s favorite sport (outside of Canada and the USA, who find it a cure for insomnia)? there was that French chap Zidane, who head-butted the Italian player into semi-consciousness. Let’s not forget the all-too-frequent riots in the stands.
Unfortunately, hockey fights get more attention in the American media than the game itself, and this is because of a built-in bias towards the game by much of the American sports media, who generally prefer basketball and consider hockey to be both a foreign sport and one that takes too much attention to follow.
This doesn’t exist in American cities that have an NHL team but not an NBA team - but usually, only there (Pittsburgh, Buffalo, St. Louis, etc,)
