Being a huge fan of the game itself, I truly enjoyed this book. "Jaws" takes you through 7 historic NFL games that had a lasting impact on the way the professional game was/is played - because these games introduced new coaching schemes or even ideologies that can still be felt in today's game: the grandfathers of the modern passing game, Gillman, Coryell and Walsh; defensive contributions like the Cover-2 and Dick LeBeau's Zone Blitz. Each of these schemes or concepts is demonstrated by analysis of a specific game.
The reader is taken through each game quarter by quarter describing in detail relevant plays, their impact on the game specifically and in general, including a few play diagrams. Now, if this sounds very geeky to you - then you're right. Don't get me wrong - the book is no play-by-play box score compilation. Jaworski and his co-authors focus exclusively on one team and the decisions made by that team's coach or coordinator and how each play figured into the overall scheme of that coach.
The book is fun and easy to read, a huge ensemble cast of former and current players and coaches get to have their say, and depending on your age, you either get to gain some insights of the NFL before you were born (Sid Gillman's Chargers and the Steel Curtain were before my time), too young (I only knew about Don Coryell, Dan Fouts and Kellen Winslow Sr. from highlight reels), or you get to re-experience great games that you may have seen but not thought about for some time.
What I really like was the back and forth between offensive and defensive innovations - it demonstrates the arms race in the NFL very well. The offense starts to air it out - the defense catches up. The offense creates ever more complex formations and plays - the defense overloads and blitzes unexpectedly, and so on. The book also offers some refreshingly raw language that you'd expect from players and coaches in football, instead of the highly polished "speaking but not saying anything" in today's media-centric league.
The reason that I'm giving it only 4 stars is that the chapter titles are somewhat confusing sometimes - Sid Gillman's Vertical Stretch, for example is showcased in a game where the Chargers won by relying on their running attack. Which they could do only because the defense expected them to air it out, but still. The Air Coryell chapter is is actually more about Winslow's breakout game, and the begin of the receiving tight ends of the modern era.
But these minor inconsistencies didn't really bother me. The price did. Now, unless you're a die-hard NFL geek looking for something meaningful to do while ESPN is showing skateboarding or oval car races, wait until the price drops. Oherwise - read this book.
