I'm very relaxed and enjoying life. But I also know that pitching injuries are serious business and so is developing healthy pitchers. There's no magical formula and even if you do everything by the book (whatever that book is) it can still go wrong. Which begs the question - why take unnecessary chances?
I'm not trying to be difficult or a jerk but re-read what you put. You justified your 15 year old son pitching 130 pitches just to win a game. You're going to develop a sign to have your son tell the coach he's too tired. Which if he's not too tired then it's a lie. The more productive thing is to have your son have a conversation with the coach. If that doesn't work then you have the conversation. If that doesn't work then go to the AD. If that doesn't work then then you need to know everything you need to know about all the people at that school. At this point you may need to remove your son from the team. If it gets this far you've stuck by your convictions and taught your son about character instead of lying.
Just saying
TPM Happy New Year to you and your family as well. I would love to post more but I'm staying super busy doing the AD job.
