Hockey is a great game and refs are out there because they enjoy the game too. As an official, I can tell you that I enjoy watching a good close clean game more than anyone and watching from on the ice is a privilege.
Officials are worthy of respect and if they make a judgment call you disagree with, yelling at them, criticizing them, is not going to change the call. In fact it actually helps their eyesight quite often and they see your team's infractions more often.
Going forward there will be zero tolerance. Managers, parent liaison or team staff need to enforce respect for officials. Spectators that are abusive towards officials will be asked to leave the arena. It is unfortunate that we have to remind people in this day and age that this is a game, it is for fun, and respect is mandatory.
Thank you and Thank your officials
