Jack Nicklaus, "Golf My Way". Fireside Books, 1974.

"But his theory seems to explain a shot I hit at the par-3 fifteenth in the second round at Firestone. The choice of club lay between a two-iron and a three-iron, and I decided to go with an easy two-iron. Coming into the ball I was deliberately 'soft' with my hands. I've never hit a better two-iron in my life! The ball finished over the green.

"Maybe this explains what happens on those good drives where I have a 'soft' feeling in my hands through the ball... My hands merely went along for the ride."

I think that Jack is saying that he didn't use the muscles in his hands, wrists and forearms to actively "Fire" the Club at the bottom of his swing.
