IN THE SPRING of 2008, the NFL was in crisis. A hard-charging United States senator from Pennsylvania named Arlen Specter had launched an investigation into the Spygate scandal. He tried to determine how many games the New England Patriots' illegal videotaping operation of opposing coaches' signals had helped the team win and learn why the NFL, under the orders of commissioner Roger Goodell, had destroyed all evidence of the cheating. By May, Specter -- a former Philadelphia district attorney and a lifelong Eagles fan -- was so angry at the "stonewalling" of his inquiry by the league and the Patriots that he called for an independent investigator, similar to the Mitchell investigation of steroid use in professional baseball.
