Be happy sitting in the stands. Obviously, detailed insight into something you're passionate about is beyond you. This was a terrific book and though written years before Moneyball was even a gleam in Billy Bean's eye, it is more comprehensive and includes the human side of the game as well as the technical side. I only write this response since your erroneous and childish take on this book pops up on the front page of this books "customer review". The passages about Tony Larussa and the quotes from Willie Stargell are beautifully moving as well as insightful.
You sound like a guy who would rather watch the Pepsi Field of Dreams commercial and take that as literal baseball, than challenge yourself to gain any realistic insight. Your review is unfair and without merit.
