Another area to consider, is how the grip of the bat effects the bat path and extension.
The grip changes as the swing progresses. a death grip will definitely mess things up downstream.
I use backchaining quite abit, its not possible to backchain with the ball on the tee, so i start with contact, almost always.
I will move the tee around to show how extension, and contact with body rotation, idealy, should work.
last night i did use direction, (Howe) and explain how the the hands will tell your body where to go after launch.
