Leg Drive Mythology And Its Price

Despite The Way's popularity, The Truth was -- and is -- as Homer's analysis suggests: Most 'leg drivers' begin their Start Down by shuttling their knees forward in an exaggerated fashion. This causes the Knees to Bend beyond their Impact Fix degree of Bend, lowering the Head and with it,the Left Shoulder Center of the Stroke. This faulty move is Bobbing, the Third Snare (3-F-7-C), and unless there is a compensation by Impact, the disruption in the Left Shoulder-to-Ball Radius will produce disastrous results.

In my schools at that time, I illustrated these concepts using swing sequences of Jerry Pate , the Poster Child for the exaggerated Downstroke Knee Bend and its resultant lowered Head position. The necessary compensations(2-J-1) to shorten the suddenly too-long Radius (Left Arm and Club) -- namely, the bending of the Left Arm and the pulling back of the Left Shoulder at Impact -- were in full flower. I don't believe it coincidental that Jerry's career was cut much too short by injury -- specifically, Left Shoulder injury.

In a Pivot Stroke, the geometrically correct Start Down is led by the Left Hip Slide. This tilts the Axis of the Stroke (the Spine), and allows the Right Shoulder to deliver the Loaded Power Package correctly Down Plane into Impact. The Knees serve as Anchors (7-16) during this process, stabilizing The Machine by maintaining its Pivot Center, the Stationary Head.

What I wouldn't give to have known then what I know now...

Yoda does indeed recommend keeping the Right Shoulder 'back and down' (On Plane) per 7-13. However, it is the direction of the Hands and their Loaded Clubhead Lag that garners my five-fold "Down, Down, Down, Down, Down" recommendation.

Down the Delivery Path.

Down through Impact.

Down through the Aiming Point.

Down through the Low Point.

Down Plane to the Both Arms Straight Position.


So, Load the Lag and take it all the way down, and I'll see you in the Winner's Circle!

The Hip Shift is the Weight Shift.

When the Weight shifts, the Hip Shifts.

When the Hip Shifts, the Spine -- the Axis for the Shoulder Turn -- Tilts (lower portion toward the Target / upper portion fixed by the Stationary Head). This enables the Right Shoulder to thrust and support the Hands directly toward the Ball. Now . . .

The Hands, in full command of the Hands-Controlled Pivot, can aim their Straight Line Thrust toward the Ball.

"The Power Accumulators are the two Arms and the two Hands."

And they must have a stable Lower Body to efficiently do their work.

Drill: From the Top of the Backstroke, throw a golf ball at a golf ball on the ground. Clear the Right Hip, then . . . Straight Line Thrust toward the Ball. No matter the actual Path of the Hands -- Straight Line or Circle -- that's the idea.

A Start Down that begins at the Feet (and that ultimately pulls the Power Package downward toward the Ball) gives the Stroke maximum Swing Radius (7-17). A Start Down that begins from the Knees gives less. And from the Hips still less. And from the Shoulders, even less.

So, the longest possible Swing Radius begins at the Feet. A Start Down that begins from any other Component shortens the Swing Radius and therefore produces less Power for any given Hand Speed.

Regarding the properly executed Hip Slide:

It will not result in a Sway (4th Snare / 3-F-7-D). In fact, it is exactly this 'Hula Hula' flexibility that produces the Axis (Spine) Tilt (7-14) necessary for the Line Delivery Paths (10-23-A/B/C/D) and ultimately the Automatic and Snap Releases of 10-24.
