It’s something to say about the late Mike Dunaway, because he was generally regarded as the longest driver human on the planet back in the 80s (even being hired as the Callaway club protot-type tester for their original Big Bertha driver).
However, I do think he could have been even more powerful and longer, but I’ll add the caveat that his college football career was ended by a leg injury, so I’ve never been sure that he wasn’t doing the best he could in later years when he took up long driving.
Let’s say that he may have been swinging the best he could due to limitations from a lower body injury serious enough to end his football career.
Even if that’s the case though, I would still assert that he either could have been longer with a fully-functional lower body, or he simply could have been longer.
Mike Dunaway Iron – DTL
I base that on looking at his down-the-line mechanics, which everyone who has been around for the past year will know that of which I speak when I say he had a great “One Major Move” and of course, that awesome flat-heel impact through the ball with this iron:
The issue is not so much the shifting head on the back swing, which you can’t see anyways here, but rather that top position forced by Dunaway’s very low heel lift with the leading foot.
Everything Dunaway does with regards to mechanics is flawless, really – even with the part I don’t like, that very low lift, which causes that compact top position, this is how you would make a mechanically-correct back swing pivot with a very low or no heel lift.
You see the same thing with a driver swing shown up the line from another video, below:
Mike Dunaway – Driver Swing UTL
His downswing, I have called the most leveraged down swing and “3 To 9” sequence I have yet to look at closely, and this is the thing – it could have been even more more leveraged, in my opinion.
I’ve been looking at his swing from the down the line and face-on angles in the clip from which I got the above swing gif. and stills, and I can duplicate that action.
What I am finding however with my SwingRite is that, yes, it’s a very leveraged and powerful downswing, but my personal back swing pivot with a higher heel lift (which produces more hip turn) provides more leverage on the downswing.
That makes perfect sense – if the hips and legs are the motor driving the pivot and downswing leverage, then more hip turn with the same action would have to provide more leverage, all other things being equal.
So, there’s nothing I would ever say about his downswing action, because I’ve been chasing it for years and should be able to duplicate it. I’ll even do it from his center-biased stance!
I’ll wager though that when I do get back outside, I’ll be able to provide the proof with numbers that swinging in the optimal MCS mechanics (translation: as laid out in the EMCS videos and the MCS Golf Swing eBook) provides more leverage to the same person using Mike Dunaway’s backswing mechanics, since both swings will have the same downswing action.
Can’t wait ’til spring!
