What do you feel Homer missed or wasn't complete enough with TGM?Well, just the fact that someone would even attempt such a daunting task as to understand not just a
good golf swing but all possible geometrically correct
golf swings is more than a lifetimes work!
That being said, Homer did make a lot of progress.
However, the most shocking omission in TGM is the missing form 1 lever that would be "The Pivot". By his own admission, Homer, called the pivot the master accumulator, which needs a lever assigned to it by law.
In the golf swing, power is created by a series of levers, moved by muscular contraction. Nothing new here, we live our lives in bodies that are based upon these complex level systems. How can we move anything, even a finger without engaging some kind of lever.
Homer offers in his book a primary and secondary lever assembly.
Now, certainly the rotation of the torso on top of the hips, supported by the legs and feet, pressing into the shoulder fulcrums moving the weight of the arms, hands, and club certainly creates a lever assembly.
As the torso rotates, it creates pressure in both shoulder sockets, not just the left armpit. This is clearly obvious because no one that I have ever seen can hit the ball as far with just one arm on the club as they can with two.
So again, if the left armpit is the #4 pressure point, then we need to include the right shoulder joint also, because it is being pressured by the same source of power, especially if you are rotating flat or more level to the ground as many great strikers do.

There is nothing mysterious here, this is just common sense. The pivot is the primary lever assembly of a full golf swing. Homer's right arm thrust, and wrist cock levers ride on the sails of the pivot. Enough said there.
Another glaring oversight is the absence of a stationary right elbow option through impact. I sometimes refer to this as the frozen right arm.
In the TGM world, you see a lot of confusion and disagreement over hitting and swinging. Homer discusses how "The mystery of golf fades away when right arm participation is understood" or something to that affect.
Well, by not including a frozen right arm option in his component catalog he certainly made sure that his followers would continue to be confused or at least debate endlessly about which of the two options is better. But the problem is, that there are three options not two, and the missing option happens to be the one best demonstrated by the worlds finest ball striker...
Ben Hogan.
Big Problem.
Let me explain more clearly.
The right arm can drive actively into and beyond impact. Sure.
The right arm can also be passively pulled into a straight line post impact by
centrifugal force. Ok
OR
The right arm can pull against centrifugal force, contracting and trying to stay bent, and if the shoulders are rotating level, this sensation can be bigger than life, and VERY real. If the pivot is not as strong and quick as it potentially can be, then you might see the classic chicken winger.
Horton Smith, Lanny Watkins? This need categorization, not another hole to stick your ostrich head into.
So, what does this do? Well, if the right arm is allowed to straighten fully, it elongates the path of the clubhead, and creates a very different situation, than the model a figure skater would use as they pull their limbs inward to speed up their rotation.
This is not hard stuff you wrap your head around. Similar thing with the hammer throw in the Olympics and other similar sports.
Now, if Homer personally didn't like this.. fine.. but if his objective was to catalog the golf swing in an all inclusive way, then he really dropped the ball on this one.
Next topic. The Feet.
Homer said "The golf swing should start at the hands or the feet. preferably the feet."
Now if you read TGM, Homer talks about the feet, their position on the ground, open and closed, and a bit about shifting weight.
But, this is where we really get incomplete information. If we are shifting weight, where is that weight being shifted? From the right heel to the left heel? Center to center? From anywhere "right" to the ball of the left foot as Trevino and Knudson talked about? For the better players, they need to know specifics. There is certainly room for additional 25th or 26th components here for cataloging the options and variations that are available to golfers dealing with their foot pressures. The feet are responsible for the handling of both vertical and horizontal
ground forces. And these forces are intrinsically tied to not just deliberate applications of ground pressures, but also how steep or flat the shoulder rotations are and angle of the swing plane itself. For instance, the feet are going to be dealing with a lot more rotary torquing if the swing plane is closer to 45 degrees(flat) than say 60 (being more upright).
We could add another component for foot torquing, inward squeezing, outward pushing, or any other methodology that both adding stability or support, resistance or aiding directly to
post impact torso rotational speed.
Now if we look at the golden core mantras of TGM the flat left wrist, a clubhead lag pressure point, a straight plane line, and then stationary head, balance, and rhythm. What we have are vapor trails of proper movements.
I won't get into explaining all these things here, but let's just look at the FLW. This is something best created by a post impact accelerating pivot. That way you pin the left wrist flat... is with force, not by trying to push the club forward with the right arm or taking a pork chop divot that slows the clubhead down and literally fakes the FLW for the pretty picture on the camera. The way to get a FLW is to be able to do it NOT taking a big divot. If the pivot works hard enough post lowpoint, you can get it in a practice swing with no ball or divot taken.
Moe Norman was a good example of this with his lectures on "bacon stripping" the golf ball.
I watched Moe for 7 years while playing the Canadian Tour years ago. Moe knew what he was doing.

It's not that the FLW is wrong.. no, but you can't try to do it directly, and just driving the right arm through the impact area, does nothing more than tend to push the left arm out away and disconnected from the body, making the golf swing about 10 times more difficult than it needs to be.
A bigger question mark of course is the stationary head being an essential. Every great striker drops their head some if not a lot like Trevino and Moe did on the downswing. And if you understand the golf swing, then you'll know why. This is just simply bad advice. There is nothing essential about it at all, and history shows us this to be true and arguing the point is not worth another sentence.
So basically what happens is that because of a lot of the vagueness and obvious omissions in TGM, the student looks to the instructor for answers that they sometimes either don't know or simply just have to guess. And this is really where things go haywire, because there is no playability test to get a TGM diploma. And you simply can't know what you don't know. I mean there are 15 handicappers or worse teaching golf
with a TGM degree. That's crazy. At least the PGA of America makes their pros break 80 once in blue moon.
Both my early TGM mentors Gregg McHatton and Ben Doyle could play. That used to be the way things were. Now like everything else, all this stuff seems to be driven by profits. Ben used to authorize teachers with a difficult test and $100. Hard to imagine now.
Five of my students are authorized TGM instructors.
The great thing I really learned from both Ben and Gregg was proper hand attitudes. This is such an important concept in swinging a golf club,
completely ignored in mainstream
golf instruction. I am forever grateful for what I learned from them in this area.
Now, where Homer really shines is his chapter 2. Homer really did understand compression, the advantages of hitting the ball with a pre stressed clubshaft, and the value of mass in the clubhead. I wish the equipment manufactures would read and understand what Homer really stood for about this stuff. "Ball speed is dependent upon both pre and post impact clubhead speed" f=ma or p=mv this is the heart of
golf ball physics. Why they are taking the mass out of the clubheads ... is why we are not seeing the next great ball striker. If you are going to hit something, do it with a 2x4, not a palm tree branch.
