Coach, do you know how they did the measurements? I understand what you mean re: a disconnect between the arm and the body but frankly the arm can't help but move if the shoulder rotates...physically impossible. The arm has to hold as much "elastic energy" as it can while the core rotates to the target and the foot is planted...here is where I think you and I depart...I don't believe that what happens next should be described as rotation. I'm not an enginneer (didn't need to tell you did I?) but its more of the upper arm, elbow, wrist and fingers catching up to the body that produces the speed in of the fingers. Maybe we saying the same thing, I don't know. I do know, that I would never tell my pitchers to try to rotate their shoulders on a pitch...as only injury to the rotator would occur. jima
