Seriously? In less than 200 words, this jack-wagon has the gall to proclaim the system dead?
I have a question. Have Mike and Andy been the only swing coach/teacher(s) for any of the Tour players that they are currently with? By that, I mean are there any guys who they have been working with since they were juniors picking up a club for the first time?
I'm asking, because I don't know.
If not, then I would point to their way of teaching as a huge success, not based on Tour wins, but rather on the fact that touring professionals would turn their swings over to them at all. In other words, the guys that they are working with - as touring professionals - already have a very highly developed skill set. They already make better, crisper contact with the golf ball than 99% of all golfers around the world. If they can see an improvement, then it is definitely working.
The real proof is in how much hackers like me can improve. Whether or not Charlie Wi wins on Tour or Aaron Baddeley wins with another teacher means nothing in regard to the fundamental validity of the system. I hit the ball a lot more solidly because of it, so I know it works. All the David Leadbetter/Hank Haney/Butch Harmon tips in Golf Digest over the years haven't brought me one-one-hundredth of the improvement that simply reading posts about it on this site have. Someday, when I can afford it, I want to take an actual lesson or ten and really get my game in order. Until then, I'll have to be content with simply striking the ball better than I ever have in the twenty years I've been playing the game.
