Why do you think Hogan's right hand was so on top of the club?
To me it is the top right knucle that he wanted to control
The position of his right knuckle is something Ive been thinking about lately. Glad to find this thread again.
The pp#3 in the knuckle for Drag or the Swingers Float Loading and Longitudinal Acceleration from End in Startdown as opposed to the Hitters Drive Loading from Top (no Arc) against the first joint pp#3.
Ben Hogan placed that knuckle on the Top of the shaft so beautifully and with a definite purpose in mind, Im thinking. He used that knuckle! Not to mention his first joint. This is the ideal way Im thinking to set your right index finger and knuckle on the shaft.
He placed that knuckle on the Top of the Shaft and sensed the shaft bending along that same line in transition. The vertical plane of the LFFW. At impact after his hands had rotated off the Inclined plane, he sensed the shaft bend or load along the plane of the RFFW at the pp#3 in the first joint on the Aft of the shaft. These two planes forming a 90 degree angle. Hogan said in the Coleman tapes that this pp#3 at the first joint just sensed the (lag) pressure "going through", no pressure down and around with the index finger. Im not sure if this implies anything vis a vis the application of right arm thrust or not, that is a can of worms maybe anyways. But it does point to a Strong Single Action 10-2-B type grip with the #3 pp (first joint) on the aft of the shaft. The photos in the yellow book sort of throw me off a bit here though as the 10-2-A photo looks more Hoganish to me. Maybe Im wrong, I dunno. He for sure demonstrated his #3 pp on the aft side of the grip in the Coleman movie.
How the heck Homer Kelley working out of his garage in Seattle some years prior to the Coleman film accurately described this Drag, Lag, Float, Longitudinal vs Radial etc and the application of force through those specific pressure points is beyond me.
Here is Hogan right hand grip from the Coleman film. I used to see it as being "weak", on top, but notice the position of the first joint in his right index finger the pp#3 on the aft of the shaft and the knuckle on top of the shaft. These are purposeful ALIGNMENTS.
