If the pivot tries to add - above and beyond, alignments and rhythm suffer.

If the pivot supplies the power and one cannot add with the hands what good is extensor action??
The video of Homer swinging quote, "coming down on the ball as if to drive it into the ground". No mention of pivot only the hands driving the ball into the ground. The pivot follows the lead of the hands going down and out.

I like this one...
