Book excerpt: George Plimpton's follow-up to Paper Lion, one of his personal favorites among his classic books -- repackaged and including a foreword from Steve Almond and never-before-seen content from the Plimpton archives. In Mad Ducks and Bears, George Plimpton's engaging companion to Paper Lion, Plimpton focuses on two of the most entertaining and roguish linemen and former teammates -- Alex Karras ("Mad Ducks") and John Gordy ("Bears"), both of whom went on to achieve brilliant post-football success. A more reflective, less madcap book than Plimpton's other work, Mad Ducks and Bears is no less truthful and searching. In this fond exploration of football's values and follies, Plimpton rejoins his two teammates to discuss their careers in this brutal but captivating game. The result is an astute exploration into the fascinating lives and motivations of the players at home, in the locker room, and on the field.
