Daryl,

Is this due to the appearance of a more acute shaft angle relative to the right forearm in the prior frame with no real "obvious" change in the angle of his right forearm and right upperarm (I think that's what I see). I'm assuming that the only way to get more left wrist cock while maintaining a level right wrist would be to have the angle between the right forearm and upper arm "decrease".

Also.... it does look like he maintains a slightly bent LW coming into release.

I don't think so. Look at Frame 11 - the Clubshaft is parallel to the ground and at 90 degrees to his right forearm.

Grab a Club and get into this posture. The Clubshaft cannot be parallel to the ground with your hands at this location with a Level Right Wrist. Just try it. You’ll need to Cock your Right Wrist.

SG is a great, incredible, talented and fun to watch Pro. He cocks his Right Wrist. Most Golfers do to. Most all of the Pros do. The Pros hit thousands of Balls per week (new balls, not the ones we use to practice. And, they get free drinks, but that's another story). That amount helps maintain their hand-eye coordination. They develop feel. They can shoot 10 under. They can make 30 foot putts.

Someday, you’ll see a Pro that doesn’t Cock his Right Wrist. Maybe not

Yes, he does have a Slight Bend in his Left Wrist. But not at impact. That's the least a Pro can do.
