With his 1937 book, Ernest Jones earned lifetime spurs in golf's teaching arena. He could demonstrate his concepts and got results from his students.
Unfortunately, absent his specific hands-on intruction, his advice to Swing the Clubhead was (and is) interpreted by the masses to be from the Wrists. This is the antithesis of the core concept of The Golfing Machine: Swing the Hands(via the Pivot and Arm Swing).
de la Torre, a self-professed student of Jones, focuses on swinging the arms, not the hands (hands to the top of the backstroke; arms on the downstroke and to the end). Do you think that de la Torre is trying to avoid this "wrist swing" interpretation?
