So.... I agree that there are some referees that are not qualified to do games they are getting, and if they're older kids, it can be a problem. But how about putting some of the responsibility for out of control players, in that situation, on the coaches. They're as culpable for controlling dangerous players as the referees are if it's obvious things are going south. Maybe I'm being overly optimistic, but if it's obvious the center is over his head, why not reign in your aggressive players? Because, a lot of the time, the alternative to having that under qualified referee out there, is not playing that game. And if you think berating a referee that obviously isn't up to that level is going to help, I think maybe you should think that through a little better. If he can't control the players well, go ahead and add some more pressure to him. That will fix it.
I totally understand your take. I just think blaming someone who just isn't experienced enough, who is put in that situation because there simply isn't anyone else, is misguided. A coach who allows their players to take advantage of a situation like that is as responsible as anyone if someone gets hurt.
