So its not a terrible habit after all?
Is this "re-tracing the left shoulder" early in the downswing caught in a swing sequence?
Brian,
This movement pattern you are referring to is exactly what Dr. Scott Lephart from the University of Pittsburgh Medical Center has been discovering with many of the Tour stars he has tested with their pressure plates and 3D. He actually has found that many top players initially move into the left side beyond the original point and then actually shift BACKWARD just prior to impact and then the momentum of the club moving past themselves causes them to "finish" the weight onto the front side.
The weight actually stutters slightly from right side at the top to left to slightly back and then back forward. I think there is some evidence young Mr. McIlroy does something very similar.
That's awesome, because Dr. Scott Lephart's dad was my High School Golf Coach and I've played plenty of rounds with Scott and is one of the most tremendous individuals you'll ever meet. Haven't seen him in years.

Also awesome because it explains what I see it lots of long drivers in high speed video.
I get the pull back. I get the jump. The thing I can't seem to get close to doing right is the "run up." How do you get frame 4, back to left side, with your shoulders still closed, lots of squat, and lots of room left to rotate your shoulders and jump/snap into the ball? Sergio Garcia does the same thing. Gets to frame 4, shoulders still closed.
I feel like I try to go immediately from photo 2 to photo 5. Why such a weak transition? arghhhhhhhh.....
