Back to my original point, "reverse rotating" the hips will not help get them out in front of the shoulders as you implied. Taking the front knee back to the shoulder helps "set" the hips, allowing them to stay closed longer. When this move is timed properly it will in fact help many pitchers gain velocity increasing the "snap" of the hips there by increasing the torque of the torso by carrying the momentum of the stride deeper into the delivery. Hips simply opening before the shoulders will have your minions flying open and losing velocity. BTW, no still photos will help with this concept as the timing is key.
