To me a good golf book has something new to offer, rather than a concise summary of what is known. A great book has more than one. This book has tons of new info. This book is nothing if it is not unique. From the full swing to the pitch shot to chipping and bunker play, Rodgers takes path less travelled.
Phil learned a lot from Paul Runyan and some of that has transferred into this book with the hands opposed putting and chipping grip. Bunker play and pitching however was quite unique. Late in Jack Nicklaus career he came to help from Phil Rodgers on chipping because he was known as one of the best. If you want a clear outline of the technique he taught to Nicklaus, this is the place to go. Stan Utley's straight on bunker technique has been talked about much recently, and the method outlined in this book is not terribly dissimilar.
The full swing underhanded motion and "hitting in the flat spot" is a unique aspect of this book, especially in the full swing. It is much more common to hear the hit down, hands ahead, create lag type jargon. Phil does not advise a leverage type action and timing a flail, but rather a one piece slam the door shut action ala Sam Snead. It's a great refreshing approach to the game and picking up this book is always rewarding for this golf nut.
Contrary to most books by playing professionals, this book is so much more than a simple rehash of fundamentals learned elsewhere. Its a great addition to any golf library.
