I watched the "grid" swing too. The head does move some . . . but not a whole lot.

In this "Hell bent for leather" stroke, with maximum Pivot Participation and Arm Swing, the back of Ben Hogan's head never leaves the vertical grid line. It correctly swivels (per 1-L #2), and it Bobs a smidgeon, but it nonetheless remains anchored to the grid.

Put up a handicap golfer -- or even a TOUR player or three (past and present) -- and let's see how they do on the 'grid' test.

Now, the surveyor gets out his transit, measures off against his control points, and says "Ben set his head 1.1263 inches to the right of center at address and then moved it to .34 inches ahead of center at impact." I say, fine. Does that mean I should teach my students to set their heads 1.1263 inches to the right of center at address and move it .34 inches ahead at impact?

Please.

Students need to learn the correct Pivot -- the correct circular motion of the Body -- and the correct Action of its Components (Feet, Knees, Hips and Shoulders) . . . not how to move the Head back and forth one inch.

Learn to Pivot, guys. And learn to keep your Head still while you're doing it. Picture the spinning skater and Center your arc. Make it the subconscious lynch pin of your Stroke, and introduce a new consistency to your game.
