Never thought about too much right elbow bend at impact. Very interesting point . I guess not too many people suffer from this condiition compared to the opposite , not enough right arm extension left for the ball. Most often a right shoulder left behind at top problem.
OB
He's been a pro for a long time. So, it's been 40 years since he was over-the-top with throwaway.
Because he's shorter and played with ill-fit clubs for years, he learned to do two things: 1. Drop the club under plane 2. Keep the clubface from closing. Both were to keep the ball from hooking.
Now, with irons that are 6 degrees flat (perfectly fit for him), his compensations for the old clubs make him hit blocks. When he feels like he's straightening the Right Arm from the Top, coming over-the-top, and snapping the clubface shut, he hits the ball dead straight. Go figure...
