We want the violence. As the National TV Network Owners, we think that hockey doesn't really need to clean up it's act. Hockey is a game that is meant to be rough, and fighting is often expected. The violence that takes place in hockey games is the reason many of the fans watch the games. It is what gets us our ratings.
People enjoy a hard-hitting hockey game.
Personally, I hate hockey, but that doesn't keep me from watching the games or the highlights every night on Sports Center. For the most part, the normal violence that takes place in a hockey game does not need to be cleaned up. However, when it comes to a stick to the face, or other obvious, deliberate moves to hurt someone, is when this issue comes into play. Hockey must clean up this part of the game, to prevent the serious injuries that come along with the cheap shots. Over the years, hockey has penalized the players, and even started fining them, and suspending them from games.
