>>> I would say you want more segmented/sequenced release of energy as opposed to turning evrything too much together. Turning too much together would be "Spinning" and "flying open" and "pulling off the ball".
The KEY here is that the shoulders TILT front shoulder up/resist (rather than turn/fly open) as the hips fire to create "frontside stretch" that "keeps the shoulders in there" and prevents flying open and pulling off the ball.<<<
Hi Tom
After reading your post I reviewed the clip of Barry Bonds below. It certainly appear his hips, torso and shoulders are guilty of “turning too much together.” By your definition, his mechanics appear to exhibit "Spinning" and "flying open" and "pulling off the ball." With those flaws, it is a wonder he even made it to the major leagues.
Is Bonds turning everything too much together?
