Hmmm...
In Confessions of a Flipper you say,"You need to get the left shoulder as far away from the ball at impact".
What happens if you don't do this and have little or no rotation of your body?
Ok.
"Flipper" is a video designed to show
A way to learn to hit the ball on the way down plane.
I have more ways.
That "
A way" includes hitting the ball with lots of pivot and passive-ish hands.
If a person NEEDED to use their pivot more, they would need to "get the left shoulder as far away from the ball at impact."
But, you really don't
need to, especially on a pitch shot.
