Jack.... This isn't a similar situation, but: One of our leagues was of 6 to 8 year olds. It consisted of surrounding towns with teams of 11 players, plus a couple pooled teams to keep the 11 player limit. We had no written codes for substitutions, but we had agreed on a few things. One was that the strongest 5 kids would play against the other teams strongest 5. A horn would sound every three minutes and all 5 kids would be subbed. No scores were supposed to be kept. It was suggested that a different kid play goal each game. We had about 20 teams. Everybody played by the rules, except for one "coach". He would leave his own son on the ice during changes, while some little 7 year old kid sat on the bench. People complained to me about his treatment of children. I really had no authority over him, but I tried to fix it by going to his local organization. That approach didn't work. So, I decided to have another talk with him, even though that hadn't helped previously. So, I'm waiting for the end of his game to have my chat. I watch the game. There's one kid who hasn't played at all. Some man climbs into the bench area, grabs the "coach" by the shirt front, and punches him. Across the rink, the rest of the parents cheer. I turn and leave, because this parent had delivered his message more effectively than I could have.
