Not in this swing:

Doesn't Rickie know about "using the ground" and "shear forces"???

Huh? Clearly the knees are straightening hip joints extending...just not forward...or to his left or whatever... seems to be using the ground pretty good to me...

Is Bubba "using the ground" and "shear forces" here?:

Or here? He has levitated!:

It's hard to "use" the ground with soft spikes. Maybe you could post a swing of someone that is "using the ground" and "shear forces" so we could compare?

Well, yeah, he is standing on the ground. How is that "using" the ground?

Seems to me he is doing considerably more than just standing there....so let's frame the discussion...how exactly would you define "using the ground"? And how does one do this most efficiently?

Don't ask me to do it. I think it is junk science.

So is this the "model" for "using the ground?" For Rickie to be "using the ground" he's gotta completely lose contact with earf? Not saying Bubba's not awesome....but is this something you'd advise? Looks like Jed Clampett doin' the boogaloo..

Well, I dont know about you but the better my traction with the ground the farther I can hit the ball.

Metal spikes > Soft Spikes > flip flops.

If I go out in wet grass with flip flops I'm sliding all over the place. So there's something going on.

Everyone is using the ground (both normal as well as shear) forces during various parts of the swing in various intensity, of course. Even if a golfer does not use any single muscle contracting (hypothetically) aimed at powering the stroke his mass and gravity makes him use ground forces as well.
The fact that some of the whackers fly over the ground in the impact zone is just a temporary reaction to whacking and not that such a player does not use ground forces.

Using the friction under the feet to develop angular momentum in the golf swing is paramount.

Go stand up in your "office" swivel chair and try to swing. Absolutely no chance whatsoever. In fact, you won't even able to make a backswing past your hip.

But, the most important place to use the ground is in the transistion, not at impact.

Firm ground will respond to a force, like a player's weight or extending lower body, with an equal and opposite one. That's simple physics, not any kind of golf technique. I don't see how that is "using ground force", or how any golfer could avoid creating those opposing forces. It just happens, not because one golfer wants it to do it and another doesn't.

As far as shear forces go, if Bubba is floating on his front foot, how can he at the same time be "digging his toes in" to create a shear force that will turn the body around the front leg from some sort of lateral push? Swings like his, Stalling's and Sadlowski's prove that is a phony claim.

Maybe that driver weighs more than a couple hundred grams to them?
