The book that started it all. A visionary approach to football two decades ahead of its time. -- Brian Burke, ESPN sports data scientist, creator of expected points added, win probability, win rates Everyone who reads this seminal classic will see the game differently. The concepts are as important for football coaching and scouting veterans as they are for aspiring analysts. -- Patrick Ward & Brian Eayrs, Seattle Seahawks research and analytics Before this book, zero teams made the 'correct' choice to go for it on fourth down most of the time. Now, roughly half the league does. Football's significant shift toward analytics and the game's ever-growing popularity both owe a debt of gratitude to this book, which established some of the fundamental principles of how we think about the game today. -- Eric Eager, vice president of research and development at SumerSports, formerly at Pro Football Focus
