As a fan you are basically powerless to affect change when you are disappointed with your team. You either no longer have or never did have the athletic ability to compete at that level. Therefore the only response that helps you deal with the disappointment is to lash out at coaches/administrators. I always smile after things don't go well when a fan says a performance was "not acceptable". My immediate thought is well, what are you going to do to punish the ones who did not deliver an acceptable performance. In reality there is nothing anyone can do so venting is a way of relieving that frustration.
