Not an expert just a dad but one thing I have heard is that besides strengthening the shoulder you want to strengthen the core and get it to do more work on routine throws. By that I mean a SS, for example, may have one throw a game that needs to be all arm. The rest of the time he can get his legs and core behind the throw, and the stronger he is there, the less stress there is on the arm.
I'm not sure that is true, the stronger the core/legs are, the more stress put on the arm?
I'm not challenging you, just saying I don't know.
No problem. Just a discussion.
But 2 recent data points. My 2017 was working with a PT who made pretty much this exact point (assuming it was relayed to me accurately.) And I just saw a video of kid doing IF work at Stanford Camp 2, and the coach doing the analysis voiceover said that he wasn't getting his legs behind his throws enough.
