Hey Will,
I was just talking to Brian Grasso yesterday about you. He mentioned that you worked with Lee (sorry to hear about that
) and was very pleased that you'd be working in Chicago. Just don't let Brian get lazy (as if he had that capacity).
I'd also offer a simple explanation for the shoulder pain for repoman's son. If he is painfree with lifting and wrestling activities and it only shows up during longer distance running, consider the possibility of a "stitch". While most folks complain about a "side ache" or a cramp in the abdominal area during endurance activities, it's not uncommon to experience referred pain to the shoulder.
My guess is that if he shifts to more anaerobic sprint oriented conditioning drills (that are more appropriate conditioning for his needs anyway), he won't notice the shoulder pain.
