Fyi, I used to referee high school and college water polo. Its a very rough sport. We used to call it full contact swimming. Tempers could get high, and fists loose.
Fortunately i never had to fight a coach, but i did have one during the state quarter finals try to get in my face.
In water polo, the referees have god-like power. I told him to sit down or his team would forfeit and play no more games. He sat. He got that part right.
I never yelled at a kid. Never had to. It’s kinda like command. You either earn the respect of your troops or you resort to authority, which is a loser. This ref apparently didn’t have command presence. And of course the coach should have been tossed long before. The kids suffered, and that is wrong.
