As far as the youth levels of reffing, Fightclub is spot on. There are no consequences for bad behavior by coaches and parents. It shouldn’t be on the ref to also police parent behavior. This will continue until MN hockey and individual districts decide to put actual consequences in place. One idea I have had and tried to get heard was to have a district official randomly attend youth games in the stands. Blend in and just watch. If a coach or parent has bad behavior penalize the team. Zero tolerance. Escalate it to the point where teams start losing games and teams and associations will police it themselves.
