Justify? Far from it. Johnson has had shoulder surgery in the past. The reason I brought it up is because I am concerned that my son has similar mechanics and has a shoulder injury, not because I want my son to emulate him.
Attacks of a personal nature seem to be pretty common on this site. I understand that you are trying to show concern for my son's welfare, and I appreciate that. But I don't appreciate being accused of taking my son's health and athletic future lightly.
As it is right now, Nolan isn't throwing, period. Some light work tomorrow, but only if pain free. The discussion around our house right now is how to get healthy and stay healthy. That may include changing coaches or changing mechanics, or it may mean he has to stop lifting weights or change the type of lifts he does.
BTW, I responded to your concerns about the supination of his forearm and he isn't allowed to throw the slider. We were working on change ups and fastballs only, before his injury.
Your comments about it eating you up are right on the money. I have a son with a little talent and a long way to go. He plays baseball and football, and wants to excel at both. Its a minefield trying to negotiate through which exercises will help both and hinder neither.
Right now I'm not going to tell him to make a choice between the two. I don't think it's healthy to concentrate on only one thing at his age. And he has nearby examples of the costs of choosing one over the other...our neighbor chose to work on football his senior year (they lost the State championship game) instead of baseball and it cost him a D1 scholarship.
I would like to think that a scholarship may be possible, as I think we all would. But my first and most important goal is to take care of my son's health: physical, emotional, and psychological.
Finally, thanks for your support and interest in a stranger's kid. Your concerns are my concerns, and I look forward to further conversations in the future.
