I would cap them at 22 kids per team. If you have say 50 kids just make 2 teams either split down the middle of 25 kids each or you go the basketball way and split the teams into an A, B, or C teams. Even if you have 32 kids I would split them into teams of 16 each. 8 minute qtr just don’t allow much playing time for anyone if you are getting all those kids in the game. It also creates unsafe situations when the last 5-10 kids of a 30 kid roster is playing against a CC who has 16/17 kids and all of them are good.
