My son just recently was diagnosed with rotator cuff tendonitis at school. Over the summer and in high school he was a mid 80s pitcher but, in his first 2 outings in college scrimmages he was topping out at 75 which concerned his coaches. His arm felt dead from all the team lifting and throwing and whatnot but, had no pain until about 2 days after his last outing. Also, the trainer said rotator cuff tendonitis doesn't cause that much of a drop in velocity (only 1-2 mph)So, my question is what can cause such as drastic drop in velocity?
