The other major change that I have noticed is the pure lack of respect for high school coaches. Everyone has their expert and that HS Coach is the dumbest thing around. Few parents want to admit that that expert may or may not be knowledgeable about the game. Heck, they are paying money and would be embarrassed if they admitted that they were scammed by an expert. If you haven't noticed, I'm an ex expert. If you like what I coach, great. If not, great.
How about this?...I don't care for the hitting instruction of my DD's HS coach, and I take my DD to a HS coach for hitting instruction.
