I refereed my son's football and rugby teams. Saturday morning footie had a whole different feel to it than Sunday morning rugby.
At U9s, one match in the first half a centre forward was f/ing and blinding constantly at my boy at centre back. I asked the ref to do something about it at half time and he replied that he couldn't do anything as it wasn't directed at him! Nat gave him a couple of good kicks (on my advice) to put a stop to it second half.
Saturday morning some of the rugby boys would get a slight tap on the ankle and come off and not want to go back on (too injured). Next morning at rugby they'd get battered to pieces and you couldn't drag them off. Ever a better example of youngsters emulating the pros?
Whenever my lad broke a finger (often) we would strap it to another and send him back on (Orthopaedic surgeon parent present and approved!)
I will add that parent behaviour isn't always better at football.
I gave up refereeing the footie when I was criticised for my refereeing by one of our own parents, "I feel like I'm back at school," he said. My reply, "I teach in the poor end of the most deprived area in the country and referee rugby on a Sunday, and you want me to lower my standards on a Saturday. I quit."
