>>>McGwire does have a very focused and concentrated backside rotation. Many of the all time greats have a similar backside rotation where the back foot actually rolls over just like a pitcher, Mantle, Ruth, Aaron, come to mind off the top of my head. <<<

Hi Shawn

I am trying to understand the term “backside rotation.”--- If a batter rotates around a stationary axis, then by what reasoning could it be said that the back-side is rotating stronger than the lead-side? -- Would not the lead shoulder be rotating back at the same rate the back shoulder is rotating forward? -- Would not a “strong backside rotation” be more correct with a “back to center” type of mechanic where the front side is posted and the back-side comes around? It seems to me that it would fit that type of mechanic more than it would “rotating around a stationary axis.”
