In the episode Scott and Greg sit down with noted professional football historian Michael MacCambridge, whose award-winning book "America’s Game: The Epic Story of How Pro Football Captured A Nation" is widely considered the definitive modern history of pro football in America. We discuss his current book, which is devoted to professional football in England, entitled "Red Letters: Two Fervent Liverpool FC Supporters Correspond through the Epic Season That Wouldn’t End," his thoughts on the state of professional football and fandom, as well as his upcoming future book about professional sports in the America of the 1970s.
