If the Left Arm goes slack does that mean that Left Shoulder has ceased Pulling the Power Package? It would make sense logically. I dunno.

This kid is crazy long.

Not Bad. He's Long.................

Bent, not slack. He's Driving his Right Forearm down the Angle of Approach (good). Unfortunately, his Right Forearm Wedge is not Aligned for Hinging during the Downstroke (not good, need a compensation to realign the Wedge). So,... he Tilts his torso (which Tilts the Power Package) which moves his head Rearward. This aligns his Right Forearm Wedge for Release but with the unfortunate consequence of relocating his Left Shoulder.

I'm sure that he senses the Left Arm Wedge because he allows his Left Elbow to bend so that the out-of-aligned Head and Left Shoulder doesn't disturb what little of it he has. He is throwing the Clubhead AT the BAll. 10-2-D grip - not much Left Arm Wedge Anyway. He's using the Right Hand for Clubhead and Clubface Control.

I've been there, done that.
