Jim, the occasion you refer to, Tiger shot 65-67, they went to another golf course and Haney suggested something (a fist-ier grip) just to keep an open mind about some day, Tiger tried it out and after a dozen shots volunteered "I"m going with this." Then over the weekend he shot 70-69 and finished 4th.
I don't see how that's forcing something or evidence of bad judgment. hey talked and tinkered all of the time, often the morning of a round. Obviously a grip change is a whole lot bigger than a swing key. The book has dozens of examples of Haney holding back, waiting, deciding, wondering when to suggest, punting. Those must be tough calls and are part of his job. I don't see how that contradicts what I wrote.
I think the strength of the book is that Haney is willing to court criticism by having written it and by showing where he thinks he was right and where he thinks Tiger was wrong. Readers are free to judge that and to find fault in him. I just like a book that's well written, presents a distinct point of view and reveals something about its characters, flaws and all. There are no heroes in this account.
