I was reading one of the threads and the discussion had turned down several paths. However, at one point, the conversation was on the front foot and the concept of "closed."
To me, the key question on the front foot lies not with putting a caliper to it to measure degrees of openness, or even in trying to define whether it IS open or closed. Someone looks at a 45 degree angle and sees "open," someone else looks at the same angle and sees "closed." Not real insightful.
What I think is REALLY important is what CAUSES the foot to open. And it is hard to tell in video, because you can't see what is under the covers.
But my BELIEF is that if you COULD somehow measure it, you would find that with elite hitters, the body's core muscles and the hips beginning their rotation CAUSE the front foot to open. In the case of a really great hitter like Pujols, the hips begin to rotate while his stride foot is still in the air (at least on those swings where he TAKES a stride - principle is the same on the no-stride swing though). Proving - to me at least - that the center of his body is driving / causing rotation. Not a push off of his back foot. The push might create some forward momentum. I don't see how it is going to create rotational momentum.
Regardless, it seems to me that Pujols's front foot opens when / because his hips / core are CASUING it to.
Contrast that to a less skilled hitter - the rest of the planet - who may simply stride to a position where the foot is open. Pretty typical for young hitters. The norm, basically. No power in the move, and in all probability, the core is not involved in causing it.
Meaning the openening of the front foot actually PULLS the hips slightly open, which is a lot different than the core powerfully rotating and the front foot opening because of that precipitate and causal action.
In other words, the average hitter will often stride to a position where the front foot is open, the hips have begun to open (BECAUSE the foot has), a certain percentage of the degrees of hip rotation available will have been "used up," and no real force will have been created. Wasted opportunity.
That is DECIDEDLY different than what happens for Pujols.
My $.02, anyway.
