[O.B.Left]

Look at the difference in the amount the knees go forward and the hips as well.

In some swings the left knee does get outside of the left ankle . . . In all swings generally there is some straightening of the right knee and flexing of the left even when the knee action is double anchor. So the question becomes what knee action is best for my pattern? Knee action is a big piece in controlling the tilt of the hips and in turn controling the plane of the shoulder turn . . . in both directions.

You note the different knee action of Snead and Hogan thru the ball. Sneads left knee gets straighter faster and thus his hips don't go as far forward with the hips as Hogan. The amount of rotation in the hips and shoulders are going to differ as well and thus they have different hand paths as a result.

But what if.......we viewed the Pivot (Zone 1 power) as being comprised of a top section, the Pivot Center and a bottom section , the Hips. Now the Pivot Center stays centered of course and the Hips if you so choose can Tilt the Axis with a Hula , Hula flexibility and move to and fro laterally. In this manner the legs could be said to have the singular purpose of steadying the Pivot Center , their movement being supportive, foundational, anchor like as opposed to powerful. As if they balanced or offset the cantilever like motion of the hips. In this way, rare though it is, a flat turn of the hips in the backswing would create Right Anchor and a more tilted turn of the hips in Finish would create a straightening left leg. I bet the legs would still look pretty dynamic this way, powerless though they would be. Hands to Pivot, Pivot to Legs if you will. Hope we are in the Lab right now.

This is what I am incubating right now anyways, having been a knee driver for 30 some odd years.
