Okay try this.

Jaksa/Roder states, "A pitcher can disengage properly only if he steps his pivot foot backward of and off the pitching rubber. He must do so without interruption or hesitation, and without a movement normally associated with his pitch."

The problem is that the movement of the pivot foot has two directional movements to comply with. Up is one, back is the other. Since J/R states "backward of and off the pitching rubber", both have to be done when disengaging. Not only that, but the two movements are not assigned any particular dominance, so they have to be done equally.

If you look at the motion in terms of degrees, equal directional movements, backward and up, will form a nice 45° angle. For the knee to come up to the chest, both foot and knee are pretty much moving a 90° angle.

That's because you only moving up and not backward of...

See... :-)
