"You're going to have to put your team in a position to play meaningful hockey games and when you do that, there's going to have to be contact," Cooper said. "You do that all the time during the regular season, the 82 games you play and the couple times of practices you have a week. I'm not saying they're all battle practices, but you do a lot of those to get yourself ready, especially early in the year. You just can't run flow practices. You can't run these no touch (practices) the whole time because at some point, somebody's coming after you and you've got to be prepared for it. It's always the tough part. It's a difficult balance in practices because teammates don't usually like to hit teammates, and so as coaches you have to kind of create environments, especially competitive drills, where it's an inevitable that they're going to have physical contact because it's just not in their nature to go through and hit their own guys. We'll create some of that environment, but we don't put our players in positions to get hurt. But, unfortunately, it's part of the game. Hopefully, we can escape that."
