text: I know grades are a big thing in school but a lot of kids just want to have fun. If you enforce this policy someone that is really good and could play on a professional team may be discouraged because in middle school they didn't get to play on the middle school A team. I know it sounds ridiculous that something so small could change someone's mind. You would be surprised though. Grades do matter and all not saying they don't at all, but sports are a big way of American ways of life. B average is a high expectation for some kids, I think a C average would be a better way to go.
