Everyone knows that football is violent and dangerous. But what the players who built the NFL into a $10 billion industry didn’t know—and what the league sought to shield from them—is that no amount of padding could protect the human brain from the force generated by modern football. In League of Denial, award-winning ESPN investigative reporters Mark Fainaru-Wada and Steve Fainaru expose the public health crisis that emerged from the playing fields and examine how the league used its power and resources to attack independent scientists and elevate its own flawed research—a campaign with echoes of Big Tobacco’s fight to deny the connection between smoking and lung cancer. They chronicle the tragic fates of players like Hall of Fame Pittsburgh Steelers center Mike Webster, who was so disturbed at the time of his death he fantasized about shooting NFL executives, and former San Diego Chargers great Junior Seau, whose diseased brain became the target of a scientific battle between researchers and the NFL. Based on exclusive interviews, previously undisclosed documents, and private e-mails, League of Denial is the story of what the NFL knew and when it knew it—questions at the heart of a crisis that threatens American football—and of the battle for the sport’s future.
