Hogan knew more about the movements of the human body than possibly any golfer/golf instructor ever. McClein, Ledbetter, could not swing a club anywhere near hogan. Unless you follow his book word for word in regards to grip set up, ball position, takeaway, etc... you cannot say, with a true understanding, on whether or not his method works. They want to say things like "Hogan guarded against a snap hook and that is why de did it this way" and use that as rationalization on why they do not like certain aspects of his swing. Well news flash, what player in history, besides moe norman, did not guard against either a snap hook or a block? If hogan was alive today to discuss his book with these so called greats, he would eat there lunch. Hogan dug it out of the dirt. Hogan was not tiger in the fact that he always had a great swing. Hogan had to find his and when he did he found the best. There is so much knowledge in that book. I have read it numerous times and always find more that i think to myself "I did not know that was in here" Hogan understands the human body, understands the golf swing, and understands how they relate. That is why he got to a point where his swing was just maintance, and not fixing.
