You all know the concerns I’ve had with it, and it seems that the people at the Somax Performance Institute have compared Rory’s action with that of the greats – the post is not very subtle in calling it “The Most Unstable Swing In History.”
Says the opening in the newsletter email:
We recently became intrigued by how much Rory bounces up and down between address and impact.
Since there is no metric for stability in the golf swing, we developed one — the change in Knee Angle between address and impact.
What we found surprised us.
Rory’s Stability Score (TM) is off the charts. His swing is 2-5X less stable than golf legends of the past century. He changes his Knee Angle a whopping 65 degrees between address and impact.
There is a 37 minute video you should watch if this stuff interests you. I’ve watched it myself and these are the thoughts I have on it:
2:00 Hip Turn: Notice the part in the first couple of minutes, where “range” is described as the lack of restricting the hip turn, and Tiger Woods is shown as an example of how not to swing.
4:00 Hip Slide vs Using the Legs: At around 4 minutes, you’ll see something similar to what I talk about in the MCS videos, especially the later videos – the hips shouldn’t just slide to the target to start the down swing, you swing from the ground up and the down swing begins with the shift of the weight to the leading foot. The hips will follow naturally.
6:00 How The Legs Start the Swing: I also talk about this is in a posting on Sam Snead and the “power squat.”
**Update: Here’s the Video Itself:
Note: Some of the rotary hip stuff, I disagree with, and I believe in a tilted spine at impact, and all the best swingers had that too. Mentioning Iron Byron having zero spine change is silly, as it’s a machine, and we can’t swing like machines.
It’s not that you have a tilt that’s bad, it’s when you change the tilt drastically from address to impact (the mother of all Trebuchet Drops, in Rory’s case) – but the change in tilt is bad, so I advocate starting tilted and staying tilted. On that, it seems Somax and I kind of agree if not exactly.
I certainly don’t advocate swinging in the manner of their model, shown below, unless you have the requisite flexibility and agility – planted leading heel and no short stop slide with that wide a stance, most people are going to injure themselves seriously trying to swing like what is shown below:
Now, you all know I’m not a big fan of the rotary swing, and so I don’t subscribe to what Somax says is a proper swing, nor would I ever have any use for their training device, but the analysis between Rory and the greats is simply that- comparing his modern-style swing with that of the old time greats.
At the end of the day, the overall message you can take from Somax is that the old time swingers did it much better than what today’s swingers are doing, and I would agree emphatically with that assessment.
One thing I’d ask you to do if you watch the bulk of the video where they deal with the stability factor and knee angle is to observe the address stances of the great swingers. There’s some good stuff in there with the legs and spine angles.
Interesting stuff, and I bid you all a great day!
