Because it is completely dishonest to promote yourself as part of one of the premier youth fastpitch organizations in the area and turn around and register as a C team, which is a step above rec league. Either you live up to the name and reputation of the organization or you don't.
Can't argue with that, or with you calling them on it if they're deceitful.
But I'm trying to put myself in your position and decide if I would get worked up over it. Unless the dishonesty made my players leave and play for them, or unless I was getting run-ruled every game, I don't know that I would care. But it's probably one of those things I need to see up close. The C level should be a place where entry-level travel teams can get competitive games. If these teams are interfering with that, that would be a problem. But if they're just the ones winning the tournament by reasonable scores, then maybe not. Guess I've just decided that some teams will be dishonest, some teams will play too love, but that doesn't often affect my team.
