I totally and completely disagree.
Most really good players (by 'really good' I mean 72 or better average score) have NO IDEA "how the swing works."
For that part, 99% of all golf teachers don't either.
But these "good players" often play good for their WHOLE LIFE. Harcourt Kemp, an older amateur palyer in Louisville, has no idea about TGM or anything golf-science wise, or couldn't tell you anything smart about ball-flight, but he can FLAT PLAY.
And he always could.
The 20 or so PGA Tour players I have worked with over my 25 years of teaching often knew less than zero.
Now, some "lost it" and some "didn't" but for crying out loud, there are TGM students on the PGA TOUR who are "supposed" to know what
you think everyone should know, but these guys finished outside the top 80 on the money list, so how important could it be?
The fact is IS that PURE TALENT, nerves and all the things that make a PGA Tour player a David Toms and not a Mac O'Grady, have very VERY little to do with what they know.
Now, for what make golfer's lose it...
A little Manzella favorite:
"A Blind man comes to me for a lesson. He is walking "left" and can't go to the potty at night without waking his wife. I tell him to FEEL LIKE he he is crossing over a "heavy" right leg with a "quick and light" left leg. He walks straight. He is happy. He calls me and is VERY Happy. His wife is happy, because he doesn't knock over a lamp going to the bathroom.
The phone rings three months later, he is bumping into the right side of the room now, and needs a lesson."
Now before you answer, here is what
"you" will say:
"Manzella is a Band-Aid teacher. Just teach him (the Blind Man) that he is tracing TWO straight plane lines with his lower legs. He need to do dowel drills with his toes while laying on his back in bed and trace the ceiling tiles. Or in his case, since he is blind, pretend to trace. He needs to know whether or not he is a
hitter (someone who pushes his legs) or a
swinger (someone who pulls his legs). He needs to learn to do a RCT--Right Calf Takeaway--so he can have a precise pivot of his hips and upper body. And, he needs to have his head precisely between his feet when he walks, but he can't move his head...."
I'll tell you what,
you tell him all of that.
I just FIX HIM again, and each time, I will tighten the tolerences, and he and his wife will be happy.
You'll find the 1 of 100 blind man that wants to know everything and he'll be happy too.
But...
You missed one detail.
When I find the 1 of 100 blind man that wants to know everything (Like Tom Bartlett and Mike Finney), I'll tell them all of that too..
...except for the head precisely in the middle of the feet crap.
