I think definitely they have the ability to do that, and they should, because a lot of games, especially games that I've participated in, get really out of hand, where there are kids getting suspended, people throwing wild hits, to the point where you can't really classify it as hockey anymore. In the league that I played in, it's non-contact and there are still penalties. You have an extra game sheet that you have to fill up. Definitely I think that some games should be shut down because they're just out of control.
