I've cited this article by biomechanist Patrick Cherveny before --because I think it well states how I view "how the body works" in the context of how elite level athletes load/unload.

A few quotes from the article:
"My experiences have taught me of the importance of proximal-to-distal kinematic sequencing and how these elite movement patterns translate to elite loading patterns in the Kinetic Link, which is found in all elite athletes to varying degrees."
"My experiences have taught me of the importance of proximal-to-distal kinematic sequencing and how these elite movement patterns translate to elite loading patterns in the Kinetic Link, which is found in all elite athletes to varying degrees."
And: "The biggest misunderstanding of how the human body performs is the concept that all human motion and loading starts at the ground and works its way up through the body. This is fundamentally not true in elite movement and loading patterns."
And:"So if movement and loading does not start at the ground, then where does it start? In simple terms, it starts in the middle of the body, the core, for EVERY movement we as human beings perform."
I cite again this article because I ran across an argument wherein they were making the case that the initial posture of the post leg of a pitcher, ipso facto, CAUSED inefficiencies thereafter
Specifically they were making the argument that in slightly internally rotating the back leg/foot this somehow causes poor hip rotation.In other words the mere placement of the distal component [leg/foot] caused poor rotation.
I don't think so:
To site a single ex. here's a Koufax clip:
Slow it down to .25 Look at the post leg foot.

It's slightly internally rotated [heel is more against the rubber than are the toes]
As he starts to "move out" [leg lifts/hips start to "fall", note the stability of the back leg ie., it maintains a good degree of "stiffness" as the center mass moves away from this anchor point

As he goes into foot plant and beyond can anyone really argue that he has created any kind of inefficiencies?
Could he load/unload better by having a different initial back leg posture?
I don't think so.

I don't think so.
What I think this single example represents is what Cherveny is saying. Which is that elite athletes know how to create very good proximal movement. And the distal components react/interact to these proximal actions very effectively.
Lastly, as a guy who has worked with hitters for a long time, I can say that one of the more effective ways to load the back leg/back hip is via the combination of back leg/foot internally rotated/ eccentric loading of the hips "against" the back leg.
This combination really maximizes the torsional/ "corkscrew" effect on the back leg/hip.
This can be done statically at set-up or dynamically [what I deemed "forward by turning" yrs. ago]
[I may try to show this in the next few days].
