disclaimer that I find the author borderline insufferable, think he cheated on the regular, and have felt schadenfreude (sp?) as Patriots took a downturn after Tom Brady left, whereas Brady won another Super Bowl in Tampa Bay (a rare controlled study to help answer sports debate). This book ends with Belichick's having decided to go to UNC but before they got off to a (very) slow start.
Anyway, if it's not a hate read for you, you might well rate it more highly. I could do without all the "here's how this applies to your job" stuff that seems to be on trend for books by famous coaches, most of which seemed unremarkable: explaining his slogan "Be attentive", for instance, he notes that "If you aren't attentive, then it's only a matter of time before everyone knows how inattentive you are. And they won't be happy about it." [p. 267]. So true. And if you can't fathom how "do your job" or "work hard" or that planning is important might apply to your own context, I'm not sure you're ready for a responsible position of any kind.
A lot of the hagiography of his Dad and other Naval Academy coaches, Lawrence Taylor, Bill Parcells, Tom Brady, Gronk, etc. is well-known, but I hadn't known that Belichick attended, and played football for, Phillips Andover Academy. Not something I would have associated with his brand.
some interesting Patriots anecdotes, and he definitely has a near-photographic memory for players and plays. Not sure he has much of a writing background, though. He alludes to being inspired by Ray Dalio, author of "Principles" and says "by the way, I acknowledge right here that Ray has given me permission to borrow his term, "principles," which I will use in this book" (p. 5). Pretty sure that would be covered by fair use, Bill. In case not, I hereby give you permission to use the term "fair use" in future writings.
