Here is my personal analysis of Robert Rock's swing.
I have noted that Ralph has a lot of sympathy for Wayne DeFrancesco's belief that a golfer should use ground forces to generate swing power, and WDF is a fanatic about his "belief" that a golfer's head should drop in the early downswing (as a golfer acquires the Sam Snead sit-down look) and that the head should then elevate near impact as the golfer "jumps up" over a straightened left leg. WDF uses Tiger Woods as a role model, and TW has manifested an exaggerated up-and-down bobbing motion of his head in his recent swings (last few years). I totally reject this "belief" in a need to create a vertical up-and-down force in a golf swing - as if one were a high jumper, or pole vaulter, who want to elevate their bodies off the ground. I think that the full golf swing is primarily a rotary motion of the torso and arms, and I have never seen a convincing explanation of why a golfer should bob up-and-down during the downswing action.
Ralph also has a lot of sympathy for the idea of an active pivot thrust after impact, a CP-arm release action and and a no-roll hand release action - as seen in ABS golfers and SnT/Foley golfers. I think that it is an excellent alternative way to execute a golf swing, but I personally favor a traditional swing (like Robert Rock's) where one doesn't use a pivot-thrust action and where the golfer uses a CF-arm release action combined with a full roll hand release action.
Consider Robert Rock's backswing/downswing.
Here is his swing video
Here are capture images from the swing video.
Image 1 shows him at address. I have placed a red line on the top of his head as a reference level marker for his head position.
Note that he has rightwards spinal tilt and a neutral left arm/neutral grip.
Image 2 shows him at the end-backswing position. He has simply rotated his torso around his rightwards spinal tilt without using an arch-extension maneuver as seen in SnT golfers. Note that he has maintained the flex in his right knee and he has not straightened his right knee and elevated his right pelvis - as seen in SnT golfers. His pelvis has remained stable and his head has not elevated due to any "standing up" motion (change in the degree of spinal inclination) during his backswing.
Image 3 shows him at the end of the early downswing (when the left arm is parallel to the ground). This is the "hip squaring" phase when many golfers (like Tiger Woods) acquire an exaggerated degree of knee flexing that causes their head to drop. Note that RR's head does not drop more than 1" and note that he doesn't have an exaggerated Sam Snead sit-down look.
Image 4 shows him at impact. Note that his head has not elevated despite a straightened left leg and extension of his left side of his torso. Note that his left pelvis is only slightly elevated (slightly positive O factor) and that he doesn't manifest an exaggerated "jumping up" action as often seen in SnT golfers.
Here is Troy Matteson's SnT swing.
Here are capture images from the video
TM has such an exaggerated "butt-tuck-under-the spine" action and exaggerated "jumping up" action that his left heel is off the ground at impact.
RR is rock-solidly grounded at impact and he is not air-borne at impact.
Here are capture images of RR's followthrough.
Image 1 shows him at impact - note the FLW/clubface facing the target.
Image 2 shows him with his clubhead about 12" after impact (P7.1 position) - note that his FLW/clubface is still facing the target. That's a sign of a stable clubface through the immediate impact zone.
Image 3 shows him at the P7.3 position where he has started to perform his full roll hand release action. Image 4 shows him at the P7.6 position where he has completed his full roll hand release action.
Note that he utilizes a CF-arm release, and he doesn't use a CP-arm release. Note that his pelvis doesn't thrust forward and continue to actively rotate between P7 and P7.6.
I think that Robert Rock has a superb golf swing , and it has the all the features of being rock-solidly stable. I think that he is a perfect role model for golfers who favor a traditional golf swing. I obviously also like the fact that he maintains an intact LAFW/FLW throughout his swing action.
