In the debut episode of the Purple Insider Book Club, Matthew Coller talks with Doug Farrar of USA Today, whose book The Genius of Desperation brilliantly lays out the history of innovation in the NFL. Doug discusses how the AFL set the stage for today's game and how teams beat the Vikings with innovative strategies in the early Super Bowls. Plus he discusses the origins of different defenses and how that connects to what the Vikings are set to play this year under Ed Donatell.
