Kevin - we see reality differently.

I think that BM and BR are performing the same pelvic rotational movement from a biomechanical perspective, except that BM is deliberately allowing his head and upper torso to rotate as far as possible to the right (head is outside his inner right foot) to exaggerate the drill effect and to get that clubshaft perpendicular to the ball-target line. By contrast, BR is probably attempting to keep his head more stationary and within the boundaries of his stance.

Jeff.

I'm confused Jeff . . . could we clear up exactly where we stand here . . . are we moving our head or not? We have one post where we've got people moving their head to their right foot . . . then we have posts where we should leave the head where it is . ..

I'm lost . . . what was the point of the deal with the head moving over the right foot? What exactly is the biomechanic "optimum" . . . and "optimum" to what end?

I think I got lost in all the spine talk as to what the point of this is . . . would you mind restating your position? Sorry to be such a doofus.
