Contrary to what some of you here believe, Hank Haney is not an idiot. He was with Tiger long enough to know that TW's legal team would have him sued six ways to Sunday if this book was anything close to the "hit piece" you guys claim it to be. You can choose to disbelieve anything that's unflattering to Tiger, but the reality is that what Haney is saying is likely all true, at least the parts that describe actual events, conversations, etc.
There are other parts of the book where Haney is offering his opinions about things, and those are open to conjecture. I can see where tension may have crept into the relationship, and personal feelings can color our viewpoints on things. You can call Haney a traitor for coming out with this book, but any unbiased observer would likely agree that what he says in the book is the fruit of his actual opinions and feelings.
At the press conference where the terse exchange between Tiger and Miceli took place, it can be argued that Tiger didn't want to discuss anything about the book to avoid giving it any publicity, and that's fair. Of course, if that was his goal, he only helped publicize it more. But you could also make the case that he refused to talk about it because there were at least some uncomfortable truths there.
Knowing how Tiger has strictly controlled media access through the years over his private life, I just don't see him not taking some sort of legal action if indeed there are mistruths or distortions of the facts contained in Haney's book. Regardless of what any of us think, the book is sure to be a big seller.
