That is an urban myth. I have coached 16 youth teams including 1 this year. I have only had a problem once I would consider serious with a parent over that entire period.
USA Hockey and most rinks have a zero tolerance policy.
i beg to differ. my son has played travel ice hockey for the past 7 years. to date, i haven't seen any parents brawling, but there has been the potential more than once, depending on the teams. Some are worse than others.
