>>> PersonnalyI believe most hitters I see in the majors get off the back side.They say when you walk it is a series of constant falls caught by the next foot plant.As I see hitters during their stride or a guy like Pujols who some feel him to be a no strider,but during the stride or in pujols there is a shift forward while the lead toe is on its tip.You watch the rear leg during the stride phase and you see the leg become less vertical,the knee gets out in front of the foot by lead toe touch.I feel the weight has to be shifting into the lead leg to have resistance for the lead hip to rotate against,I think that if you dont get off the back side then you would have to be a back side hip driver to force weight forward into rotation.When guys get fooled and get out front this is from weight shift and unable to adjust for offspeed.<<<
I am not sure we have a disagreement of mechanics or in our definition of terms. I have always stated the weight on the back-foot becomes lighter (batter getting off the back-side) during rotation. I do not believe however that this is necessarily due hip-slide or the body's forward velocity.
For the sake of clarity, I will place below a couple video clips that describe my position on weight-shift and what produces hip rotation. With these as references, you can point out where we may disagree.
Does "Weight Shift" = Momentum (p=mv)
Do the hips rotate like a gate -- or a revolving door?
