Coach picked sons friends for the team

I could really use some advice. My son who is 12 and has been playing basketball since grade K recently got put on the "B" team because the new coach picked his sons friends as teammates. My son has more talent and experience than at least 5 of the players he picked. One of these boys has never even played before, and can't make a shot. Another is about 3' 11" and also can't play. These same boys weren't even considered for the rec travel team and were cut. But because the coach is friends with their parents they made the team, and my boy got cut. I am so upset, because EVERYONE has come to us and told us how wrong it is. My son is just questioning everything in life. I have a meeting with the Super of Schools tomorrow. Any advice?
Thank you.
