Book excerpt: Drawing on the author's 30-year study of football statistics, this book presents new methods for analyzing the game in different ways. An examination of known distances for missed field goals offers an accurate method for evaluating placekickers. Reassessments of punters and running backs are included, along with an overhaul of the NFL's passer rating system. Topics previously unexplored through statistics are covered, such as momentum, defining "What is a dynasty?" and "What is a Cinderella team?"
