Boss . . . Could you comment on the Right Foot of L. Nelson versus Sam pictured below? Is this a difference in alignment? Loading procedure? Method of acceleration?

What are the causes of the difference in the right heel? And what would be the pro's/con's of both?

As is Billy Casper, Larry Nelson is a 'Right Foot Dragger' through Impact. It is a very natural action, the same 'foot drag' you get when you skip a rock across water with gusto.

Personally, I like Sam Snead's more stable Right Foot, but Larry's action gets the job done, and I, for one, would not suggest that he change it. The procedure does not interfere with his Pivot Stability or Balance, and it has served him well throughout his career.
