I’d say If someone makes your kid feel like a zero, worthless, degrades them etc. I’d confront that coach in 10 seconds. Plus leave the team. I don’t know anybody in that situation. I think the point was unhappy about roster sizes, kids not playing much, just not a real good situation. Clubs taking peoples money and more or less forgetting about them. Do you have your kid quit over this? I say finish the season and move on. Chalk it up to a mistake. Life lesson.
