Wales, you hit it on the button. The major problem here is that most kids are so zeroed on in pitching, whether coaches or parents or what not, and they haven't learned how to throw! I put it this way on another post:
A baby has to crawl before it can walk, and walk before it can run. A kid has to learn to throw the ball before it can pitch. What I see it is a classic cart-before-the-horse situation---kids are, from the beginning, inundated with mechanics and such, and they haven't learned how to just plain throw the ball. No wonder there are so many injuries, so many 10-and 11-year-olds heading for TJ surgery!
A kid has to start out learning to just plain throw the ball---and throw it with intent. And then, one can start with some basic mechanics... :o :shock:
