Just my opinion. I refuse to take the stance that "a few soldiers must die" to win the war, so to speak. I am in favor of prohibiting breaking pitches until 14 or 15, mandatory pitch counts and innings per week.
That being said, a pitcher accepts the risks inherent to the position by taking the mound.
As a child, he's limited by the coaches as to when he comes out of the game. The pitchers responsiblity for an injury ends at a reasonable pitch count per game, per week. He has to do what the coach says.
Obviously some coaches and most parents don't know what is reasonable for most kids. Snapping off curves for 20 innings a week at 11 is just not reasonable.
If someone can't see the relationship between increased elbow surgery and the growth of travel leagues, showcases, and year round baseball in the sunbelt, its because they don't want to see it.
