I agree that the power doesn't come from the front side only. The shift of center mass, forward movement, fall from the back leg, and momentum therein loads the front leg, stretching the muscle spindles adding to their forceful contraction resulting in a more powerful extension of the front leg that pushes the front hip rearward adding power to and creating a greater hip rotation.I'm not seeing how you can make that correlation, all your basically doing is saying "See the one on the right looks better so, I'm right." What I'm saying still applies to the one on the right and left. The difference between these 2 swings, is that the player on the left is not maintaining separation into foot plant. She slots mid air. She doesn't maintain posture either. The one on the right still unloads the back leg. You cannot get on to the toe of the rear leg without it unloading. How long a player is going to store energy onto the front is variable based on timing. I would like add also that I'm not advocating that all the power comes from the front side only.
The rear leg is merely a stilt which the body uses for support when the front leg is elevated and the center of mass being shifted forward, the hitter falls forward gaining momentum via gravity. In some swings, the rear leg outwardly rotates and because it is closed chain when it does, the pelvis is turned.
There are many swings that don't utilize these movements, and they are weak swings.
