First let me say that I am an ex-professional golfer and totally understood everything Hank says. But, I seriously doubt that the average golfer will understand or comprehend the vast amount of technical swing comments made in this book.
Secondly, I do not agree with the fact that Hank felt the need to write this book. There is so much personal trust in the relationship between athletes and those that surround them that there is an unspoken code that must be respected. I feel that Hank shattered that code and I will never respect him for that... only time will tell how Hank's reputation is effected.
But, thirdly, for those out there who want to get a glimpse of the intense work and pressure that a world class athlete is under, Hank does a nice job of getting that across. Had there not been the stigma of "kiss and tell", I would have thoroughly enjoyed the book. And, of course, this was Hank's opinion and story... I'm sure Tiger's recollection would be much different.
Was the book fair... maybe. Should it have been written... absolutely not.
I would also like to make a technical comment about the narration. Hank did a great job which is unusual for a writer who chooses to narrate. But, there were times in the narration, that there seemed like another voice came in like a voice over... I'm not sure if it was Hank doing a voice over or some other narrator cleaning up mistakes. Whatever, it wasn't annoying.
