[Yoda]

If you are trying to prove that all great players had the head precisely between their feet and kept it dead still on the backswing and on to impact...

You can't win.

You're right, Brian. Fortunately, that is not the case.

But thank you for the Billy Casper illustration. With his chin is pointed at the back of that Ball from Address to the end of the Follow-Through and with his Right Forearm Pick-Up, he is my favorite example.

The truth is that, unlike your self-mandated Head position, Homer Kelley advised...

Wherever you position your Head at Impact Fix...

THAT is where it must stay.

Ideally, though, according to the same Mr. Kelley, that position is "precisely between the feet." This is TREMENDOUSLY important ground we are exploring here, ground that will revolutionize conventional golf instruction.

Actually, we're all the way back to 1905 and Harry Vardon's book, The Complete Golfer ...

"The head should be kept perfectly motionless from time of the address until the ball has been sent away and it is well on its flight."

And Mr. Vardon had the Game -- and the Pivot -- to prove it.
