Dad thinks he's Earl Woods. There's a reason his son has played on a dozen different teams. And it's not because he's talented. It's because over time parents and coaches can't handle the selfishness. Stop trying to squeeze blood from that Stone. Let him play and enjoy it before he regrets it all. And let the other parents enjoy it too.
They played at Halloween Havoc last year and the refs had to stop the game 2x to tell that guy to relax and leave. Then they lost to the Warriors and dad was fuming!
