Another point to consider is that of ER of the upper leg in preparation to IR....

The rear hip rotates to the ball, the rear leg is pulled in that direction. Notice the singular, hip. The front hip action is a result of the rear hip move. Much simpler for the hip to attack the target.

The hips are one bone structure....if the back hip moves so does the front hip.....the movement is in the rear hip socket where the upper leg connects....the reason you see the crease in the front groin and the front quad "pop" is because the rear upper leg internally rotates in the rear hip socket and drives the hip rotation (if your rear leg and rear hips really fuse during the coil). The upper legs are applying force against each other....
All you have to do is open your mind and try it....I bet you throw harder and hit the ball harder in one throw or swing....the upper leg is the force generator....it drives the hips open which turns the torso....hip driven rotation cuts the body off at the legs....

Stand up and try it...play a game of "Operation" except the alarm blows and your nose lights up every time a muscle fires in your thigh when "rotating the rear hip to the ball." I don't believe you can "rotate your hip to the ball" without either
A. Your front leg tries to externally rotate and bring your hip.
Or
B. Your rear leg internally rotates.
Since we have already established that good hitters don't shift to the front side then swing, that takes A. out of the picture.
So rotate to the ball, NOT JUST A SMALL ROTATION, with out the muscles of your rear leg trying to ir. Just use as you said before the muscles of your core. Buzzzzz everytime your leg wants to ir since it is just pulled.
Ok. Now next thought...say I am wrong...you do use your core muscles to rotate ("fire") your hips at the ball. Go ahead fire-fire-fire (I am picturing you now doing it). Now get your lower to fire/rotate with your core muscles AND hold your upper from rotating...separate, sequence, hips before hands (trying to think of all the terms).
So #1 I don't believe you can bring your rear hip to the ball, at least not very far without ir ing your rear leg.
#2 I don't think you can use your core muscles to rotate your lower, and use the same core muscles to resist the upper from going with it.

Yes. What really should happen ^^^^ the upper leg "drives the hips open which turns the torso", but you don't want the torso to turn when the hips turn, you want seperation, so you need to use the core area's muscles to keep the torso from turning.

True...but eventually the hips pull on the torso....the hands are already throwing the barrel at the ball without the aid of the shoulders....the torso is the middle...not the hips....

Yes I agree. I was just thinking of SBP theory of the core muscles rotating the hips, and I am saying the core muscles can't both rotate and resist rotating at the same time.
I believe the upper leg drives as you said, and the hip pulls the torso, and the core muscles resist the pull, create a stretch.

Exactly - try and fire the hips and not turn your torso....impossible....you have to turn as one piece just using your hips....
If you believe the throwing and hitting sequences are the same - you have to use the back leg as your driver...

I apologize if you are speaking of the rear hip joint and not of the hip structure
Here is an animation of a hip replacement....the action that RHC and I am talking about is all in the video clip...

The rear hip and rear leg do not fuse.
We (me, you and rhc) are saying basically the same thing. Or, at least, we agree that the hip has a ball joint connecting the leg.
Where we have a difference of opinion is that the rear leg (primarily) drives the hip. I believe the hip (primarily) pulls the leg. Although that is not the hip's main objective, but rather an effect.
Try this: lay down on your side and rotate the hip forward, using the hip. Did you need your leg to do that? The leg internally rotated; not on it's own primarily, and not because it is fused to the hip, but because of the muscular structure involved in the hip turning action.
Perhaps we are putting too much emphasis on the skeletal support. It's the muscles that should be the focus.
