If you look at this video compilation of Mike Dunaway’s swings back when he was the dominant driver on the planet (John Daly said MD was longer than him, Greg Norman called him the best driver of the ball that ever lived, etc.), you’ll see what I was talking about in my posting on the knees being “shock absorbers.”
I want to also mention Mike’s website Dunaway Long, for those who weren’t aware that he has returned to golf after a lengthy absence.
It has always been a mystery to me why Mike Dunaway wasn’t a household name in golf from the ’90s going forward.
Swing techniques have improved over the years, but you still won’t see a better swing action than Dunaway’s from years ago.
