yeh those pics look screwy. the problem i have have with the cocking drill as a lot of people teach it is that they cock the left wrist as the drill. As mac teaches it it is more about turning the club up the hands plane and the only cocking of the left wrist is a result of how much your right elbow bends. in that picture with martin his elbow hasnt bent from address, most people who do this will overcok the club at the top and then tend to throw it away right from the top.
Great points made here. Start the club back with the heel of the club head, turn to the plane and then cock UP. If your too inside or you didn't cock correctly, it will be hard for you to get the back of the left hand(righty golfer)down on the ball.

Surely not! I worked on that drill quite a bit as a youngster My TGM version of that drill is to cock the left wrist by bending the right elbow...then add the pivot...and voila!
The real problem with this drill is that it is performed from the Adjusted Address position, i.e., with the Left Wrist Bent and Right Wrist Flat. Then, a perpendicular Left Wristcock puts the Club out-of-plane with the Left Arm, thereby destroying the Left Arm Flying Wedge.
Any Left Wristcocking drill should be done from Impact Fix (Left Wrist Flat, Right Wrist Bent) or with the Left Arm and Club otherwise in line. That is why, in my recently posted Left Wristcocking video, I demonstrate the perpendicular Cocking and Uncocking from opposite the Left Shoulder. Then, the Left Arm and Club remain in line, and the Left Arm Flying Wedge remains intact.
Again, that is not the case when the Left Wrist is Cocked vertically from its Adjusted Address, Bent Left Wrist condition. This condition normally is acceptable only when using the Turning Shoulder Plane (10-6-D) with its Vertical Loading Action, i.e., true Single Wrist Action (10-18-C-#3) with the Hands "under the Club" at the Top.
