Im pretty sure they teach this at the Kegel Training Center. Does anybody believe in this Swing Slot theory? It's an imaginary line that helps keep your swing tight by dropping your shoulder so that your head is above your swing while your body is out of your way. Now that Ive noticed this thoery, I think Tommy Jones uses the swing slot.
