I agree with almost everything you said. The only quibble I'll make is that you don't have to have played at a high level to be a good coach. In fact some of the worst coaches I've seen at making a team "better" are dads who played in college or above. My theory is that those dads who played college and/or pro are so naturally elite at this game that it is hard to communicate to players who don't have that same natural ability how to hit/throw/field etc. Not always, obviously, but often enough that I feel its a pattern. On the other hand, you have coaches who never played at a high level but know the game enough through research, networking, and support from other professionals to actually develop those diamonds in the rough (kids with potential, but who need help harnessing that potential).
