Book excerpt: Insightful, poignant, inspiring, and witty, The Class of Football is a heartfelt collection of hard-earned wisdom and life's lessons from the Hall-of-Fame induction speeches of the NFL's all-time greatest players. Compiled in conjunction with the Pro Football Hall of Fame, The Class of Football brings together sage advice from legends of the game whose knowledge, leadership, experience, and athletic prowess made them heroes on and off the field. George Halas speaks on history, Alan Page on justice, Gale Sayers on perseverance, John Madden on passion, Steve Largent on mentors, Mike Singletary on childhood, Michael Irvin on family, Marv Levy on philosophy, and Willie Davis and the rest of the great Green Bay Packers on Vince Lombardi. Each Hall of Famer reflects on his life and career and, even more important, addresses how and why he was able to arrive, once and for all, in Canton, Ohio. Motivating and gripping, these wise words from nearly five decades of Hall-of-Fame history will live on long after the cheering.
