I sometimes struggle with finding ways to prove things about Mike Dunaway, because he never played competitive golf and his long drive days (of the sort that inspired Art Sellinger, founder of Long Drivers Of America) were long before the advent of YouTube.
Therefore, you don’t see a lot of “proof” of how powerful and long Dunaway was other than things like LDOAnaming him the Father of Modern Long Drive and awarding him a lifetime achievement prize for his pioneering work.
I caught sight of a great Sam Snead swing on Twitter today, and I have to tell you all, I could watch this man swing all day long and some nights to boot.
I’d say that Sam Snead has the best self-taught swing of all time. It would be hard to argue, because I would actually rate his swing as on par with Jack Nicklaus’ swing, just that Nicklaus had a better over-all game to go with the swing.
