I don't want to get into the whole "fighting in hockey" debate, but I'll agree that a youth hockey coach who orchestrates fights in practice has no place behind the bench
I am an accredited USA Hockey coach and referee and can state for a fact that the actions of this coach are not sanctioned.
There is absolutely no place for fighting in USA Hockey games or practices. It is absolutely banned. When seen, it is punished severely, usually with an immediate game misconduct and a subsequent game suspension, or more.
