I reviewed a few videos I got, namely, Golf my way by Jack Nicklaus video; How to build a Classic Swing by Ernie Els and Ben Hogan DVD by Jim Mclean.
I heard so many time “Head still…..”
See Els's head in the capture top down view:-

On the other hand, the golf swing in the Hogan at older age video really moved "a lot" to the right but when i put it on V1 solfware, he definely returned his head to near address position through impact with quite active lower body movement.
Is flexibility an issue?
