Thanks Bob.
Do you have a reference where I can learn more?
I'm sorry Garland, but I do not. I'm writing from memory, as I attended his demonstrations.
Back then, I was an Arnie fan and resented Jack up until that day, but have been a fan ever since.
He had several common sense approaches to golf that I remember.
One was to always warm up or practice with your wedge first and driver last.
He also said to never ground your club before swinging. Since you hadn't addressed the ball until you grounded your club, if you whiffed or if the ball moved, then you wouldn't be penalized.
