This is a difficult book to describe. It is very well written, and it provides what would appear to be a pretty good picture of the real Tiger Woods...both the golf prodigy and the totally self absorbed person.
If you have read reviews or watched interviews with Hank Haney, you already know most of the "juicy" parts (and they really aren't that juicy). If you are not into golf, you will probably find the book excruciatingly dull as Haney goes on at length about the mechanics of Tiger's golf swing and the details of his practice routine and of various tournaments.
If, however, you enjoy the details of golf and/or enjoy reading about the personalities of superachievers, you will probably enjoy the book a lot. I did.
In fact, on the personality side, you get a twofer. You get one man's analysis of superstar/super narcissist Tiger Woods. And you also get to observe what happens when that ego collides with the big but fragile ego of super coach Hank Haney. Very interesting dynamics!!! In the end, Haney hails Tiger as the greatest golfer of all time. But that accolade is tempered by Haney's assessment of Tiger's underdeveloped personal skills. You also get Haney's defense of his own record as Tiger's coach.
Haney does not do this, but I noted parallels between Tiger and what I have read about superstars in other fields--particularly Steve Jobs and the early Bill Gates. It is apparent that super talent and warm, fuzzy personalities are not often combined in one package (although Gates seems to have mellowed).
Haney should have probably not written this book. While he apparently violated no contracts with Tiger, I agree that he violated the implied trust between a teacher and a student. Nonetheless, we readers are better off because he did. Once you filter out Haney's bruised feelings, "The Big Miss" really does appear to be as accurate a view of Tiger Woods as we will ever get.
