When these weak B bracket kids surpass your all mighty Taz son in a few years because they actually get playing time and have fun playing, we'll see what kind of comments you will be shooting out. And your son probably won't even be playing - one because he hates not getting playing time, two they've cut him because the B kids got better than him and three because he can't stand being yelling at and embarrassed by his father.
I think the B bracket isn't so bad for a 9 year old who plays most the game, is developing and having fun.
