When I took the job I was warned that it was a mostly low-income group with disinterested parents who don’t like authority, with that info one of the first things I did when I came in as coach is implement pretty strict rules about swearing and referee conduct. Anyone who swears at practice or during a game earns 10 burpees for the entire team. Arguing with a referee is three laps of the field. After two practices this behaviour was pretty much eliminated. I’ve never had a single kid so much as throw a nasty look at the ref.
But as it happens the characterization of the group proved to be incorrect anyway, I have 20 of the nicest girls you could wish to meet. It was more likely that the former coach was incompetant (and trying to sleep with one of the players).
