>>>I have reviewed Sammy Sosa's swings in the freeze-frame mode on my VCR during my spare time this week. While he may exhibit pure rotational mechanics, I noticed that as he spins his hips, both legs are bent, and as both rotate around, it seems as if the right leg < and the left leg > come together as if they are forming a diamond <> to give a maximum velocity spin so the energy of both leg are expended at contact. Do you agree with my analysis, and why? <<<

This is one reason I am opposed to the batting theory of casting weight forward to a firm (or straight) front leg. If the lead leg is straighter (less flex) at foot plant, it would reduce the ability of the lead leg to drive hip rotation. Using only the back leg will cause the center of axis to shift forward ("back to center"). This is a far less efficient mechanic.

> jack....."If the lead leg is straighter (less flex) at foot plant, it would reduce the ability of the lead leg to drive hip rotation."....i don't understand this concept.....to me it's simple....you rotate around the front leg....i don't see the lead hip driving rotation, i see the hip rotation around a stiff front leg......and guess what ? if your front leg remains bent, then the body will have more of a linear shift FORWARD (linearly) & less rotation.....and according to mike schmidt, that's pretty much the distiction between weight shift & rotation (at least the lower body mechanics)....are schmidt & myself wrong?....respectfully, grc....
