Pivot photos of two typical Golfers are shown below with lines scribed for reference.
The Knee Action Sequence is Identical for Both Players, however the Golfers vary in the degree of Motion.
Both use Standard Knee Action:
Backstroke: Right Knee straightens and Left Knee Bends.
This determines the amount of Hip Slant (Blue :Line) and Also becomes a factor determining Left Heel Rise above ground.
Hip Turn in the Top Sequence is a little less than the Player in the Lower Sequence (Weight Shift)
Both Pass through Sit-Down between Frames 4&5
Both PLANT THE LEFT HEEL BY BENDING THE RIGHT KNEE DURING SIT-DOWN which provides a lateral shift as the Hips continue Leading the Shoulders.
This Hip Action synchronizes the #3 Accumulator Roll through Impact.
Ben Hogan returns His Head to Center of Stance during Sit-Down. Tiger does not. Tiger has his Right Shoulder and Arm On-Plane at Impact. Nicely Physical, but then Zero Right Elbow Bend at Impact.
I wonder if the amount of Knee Bend contributed to Ben Hogans Impact Geometry?
Can the Amount of Lateral Slide be controlled by the Amount of Knee Bend?

Pretty interesting comparison . . . An answer to your question yes . . . if either knee straightens the hip has more range of motion with regards to hip turn. Hogan is much more centered that Eldrick. Look how much his right hip slides in the back stroke compared to Tiger in addition to how much flex he has lost in his right knee. Tiger's head moves back and stays back. To your question look at 4th frame . . . note how straight Eldrick's knee is in comparison to Mr. Hogan. Hogan is adding flex to his left knee and it is moving left . . . thus his hips are sliding waaaaaaay more left and he straightens his left leg much later and his hips open much later. Hogan went more forward with his hips than anybody. Also look how much higher Hogan's right shoulder is that Tiger's in frame 4 and 5 . . . big time hit it solid piece and from the inside piece. Hogan has a lot better chance of controlling the face with that pivot.
thanks for putting that up pretty cool.

In regard to Tigers slightly less centered motion remember that they are hitting different shots. Tiger hitting driver, can be said to employing a special procedure. Allowing his center to hang back a touch for launch angle or angle of attack purposes. Great comparison though.

oh ya,, hitting up with the driver is the new thing.
If your clubhead travel from higher on the ball at impact to lower on the ball at separation, did hanging back with your head help you to hit up?
I heard that he switched to a 10 degree driver on Sunday. Hmm? I haven't seen video nor checked for head location.

10 degrees. Really?
Hello world er fairway or whatever!
Homer did say "to hit down and out except for special procedures". Hanging back with a driver is nothing new as you say. There is footage of a young Hogan doing it in a very pronounced manner. Dare I say at the expense of balance? In my opinion though he was mugging for the camera and displaying his long drive, high launch swing. Not his everyday tournament swing here.

Hitting UP is to reduce spin. But Clubs are designed to hit the ball while going down, out and forward.
I swear, if the pro's didn't make so much money on tour, they'd be selling shoes in the woman's department.
I dont know if that is still true for some of todays drivers. Take a look at the built in reverse shaft lean on a D3 for instance. You have to take it later to square the face unless you hood it.
I agree though that we golfers should direct the thrust down and out to both arms straight (well after impact) but the arc of the clubhead is coming up and in post low point and that, it would seem, is where they want us to make contact with the ball.
I was recently fit at Titleist and they were all over me to increase my angle of attack to a positive (rising) number. I did it with ball position and tee height, the spin numbers came way down as you say.
you got alot of lines there!! 
But I really like your stuff - keep it coming!
