I'm not criticizing his Golf or his passion for TGM and the game. However, he's not a Hitter no matter how much Right Arm Muscle you think he uses before, during or after Impact.
He's not Radially Driving or Accelerating the Primary Lever. If you want to use Right Arm Muscle to Accelerate the Secondary Lever, then by all means, do so. He loads the Clubshaft at the Top. He does not Load the Primary Lever.
He may think he Pushes with his Right Arm, but it's a Pull. Like a Horse in a harness pulling a cart. Is the Horse Pushing or Pulling? Driving or Dragging? It may feel like pushing the Clubshaft (Straightening his Right Elbow) and Pulling the Clubshaft simultaneously during the Downstroke. That does not make him a Hitter or a 4 Barrel Hitter. It's all about Elbow Location.
Everything he does is all about the Clubshaft. He's a Swinger.
