The Hogan secret was the action of his RIGHT KNEE. Right Knee at the ball during the downswing....
DG
I don't see how this could be his secret...
If you're referring to that GD article then I don't agree with you.
Unless you can explain further.
The comment about the right knee is in the book by his caddie....I don't remember the name of the book....I just remember thumbing through the book at a local borders store and finding the comments on THE HOGAN SECRET...
I actually really don't study the Hogan swing anymore (it doesn't fit in with the TGM model ie; TGM promotes the Straight Line Delivery Path for starters).....all you need is a good understanding of TGM....and your on the path to great golf.
