Dr Mann
Have you written any articles analysing the swing of Moe Norman? I have Todd Graves 'The Single Plane Golf Swing' book but frustratingly , his analysis regarding 'cause/effect' as to why Moe did 'this or that' seems incredibly vague.
Specifically : 1. Did Moe use a neutral grip and deploy a subset DH hand release action , even though he had minimal PA3 angle (from P6.5-P7?)? 2. What was Moe's arm release action? 3. Did he rotate his pelvis as per your article 'critical update: how to optimally rotate the pelvis during the downswing'? 4. How would you categorise Moe's swing (ie. type of : swinger, swing hitter, hitter) and did he use an active or reactive pivot?

DG I agree with you that Todd Graves book is very vague in terms of biomechanical/mechanical explanations. No - I have never discussed Moe Norman's swing in a review paper. Moe did use a neutral left hand grip (as seen from face-on), but he used a mid-palmar left hand grip pattern and not a low palmar or finger grip pattern. That allowed him to have a very small accumulator #3 angle when he swung with his arms extended away from his body. Moe was a TGM swinger but he used a non-DH hand release action through impact where he abruptly rotated his FLW counterclockwise through impact, but he obviously had perfect timing and a square clubface at the exact moment of impact. He had a very wide stance with virtually no active pelvic motion and his active pivot action was mainly an upper body rotation. He had an unusual degree of thoracic spine mobility that allowed him to generate an in-to-square-to-in clubhead path and avoid an OTT move (that often happens in golfers who have no/little pelvic motion).

looks like Todd Graves has responded to some of my criticisms regarding the vagueness of his book in Golfwrx (even though he knows I am now banned).
-------------------------------
Wild Thing,
Go to Singleplane3D.com. This might answer some of your questions.
As far as your critique of the book. The general nature of the Single Plane Golf Swing book is on purpose as not to confuse the reader with boring biomechanics data. For example the rotation of the trial hand as though skipping a rock is easier to interpret than saying the trail hand is rotated at 13 degrees as a function of the sidebend of the torso at 16 degrees.
Regards.
Todd Graves
-------------------
Just for clarity. Moe did not align right. At address his torso is always OPEN to the target line. His feet, with irons was OPEN to the target line. With Driver, his TORSO was open to the target line, his feet were slightly CLOSED to the target line. This represented the radius of the ball position - similar to Ben Hogan's representation of Ball position.
Todd
