Football is a game of numbers - fourth and inches, the three-man rush, a two point conversion, first down. Even with the obvious numbers in the statistics, rules and game situations, the players' uniform numbers themselves have become part of professional football and its lore. This comprehensive reference work lists all 32 current franchises of the NFL and includes brief team histories, statistics and interesting facts. Each chapter ends with an all-time numerical roster listing the numbers 1 through 99 (in some cases beginning with 00) and everyone, from Hall-of-Famer to replacement player, who has ever worn the corresponding number for that club.
