Kids leagues should have three levels, all co-ed. Competitive is for parents and kids who play to win. Go get it. Casual is for parents and kids who play for the team building. And finally Recreational is for the kids who just want to play, and the parents who like seeing energy burned. This gives boys and girls who are less competitive a place to play, while preventing anyone from dominating a more relaxed league. I mean, they can try, but it won’t be a big accomplishment.
