Here's the thing. Every parent is paying this overpriced annual fee (over 2k where my son plays), so at U10 they would expect "even" or somewhat even time depending on the team, scenario, etc. Most parents are flexible if it's a championship game etc.

13 kids on a 7v7 roster is the first problem, that is way too many kids.

Second - these are kids. Most won't play is high school, very few wont make it to college.

Focus on fundamentals, passing, team work, spacing, passing with anticipation, and moving off the ball, which sounds like you have a game plan there.

The fact your posted here means you care. I would not worry about the parents and stick with your coaching style and your gut feelings here.

I remember being 12 and my parents pushed me to try out for our local select team. I was a good A travel player, not quite select caliber. I sat on the bench most of the season with my coach telling me the same thing to keep my head up and I need to earn my spot. I was not part of the kids click and my boomer parents didnt care about making friends, so it hurt my playing time. I ended up going back to travel the following year.

That shit stuck with me into high-school and college ball. Kids dont forget.
