You'd still be in the situation where some kids wouldn't get as many games as others. You'd always need more than the 8 or 11 needed to play the games and the 'lesser' gifted ones would still miss out due to their lower skill levels.Thye could always limit each club only having 1 team per age group. This would then force the hands of parents to move to clubs where kids get a game.
Some clubs have 3 under 11 teams yet others struggle to get 1 team
I know it's all about participation at that age but nothing has a greater effect on whether people turn up week after week than getting beat every time you play. Kids from a family with some sort of cricketing background get that, as do their parents. Other parents, who've signed up their kids because it's a nice, genteel sport (in their eyes), don't get it, and that's when the demands start regarding why their young 'un isn't getting as many games as someone else's.
