Jack -

A couple of things I "see" on the Bonds clip are:

1- arms move as bat uncocks before shoulders begin to move ("untilt", "tilt", "rotate" depending on how you think of it - I think tilt)

2-the degree of "front side stretch" is more than would be expected if shoulders "just turned" with hips.

Shouders are tilting/or laterally tilting, nit just turning.

If they just turned, they would give the appearance of "flying open" with less "front side stretch", "pulling off the ball".

Instead, shoulder/scap action must "tilt" to support arms and forearms in torquing the handle which reactively keeps shoulders/hands back longer enabling a way of controlling the final load/coil/stretch of torso for well timed and quick acceleration with a generous contact zone for square contact.

Then the shoulders scaps need to connect to the torso as it unwinds by "spinal" rotation.

Lead arm retains CHP/string tension.
