In the early-to-mid-1980s, the NFL faced competition from a fledgling competition billing itself as the United States Football League AKA USFL.
Founded in 1982, it was dissolved in 1986 and provided a home for team names like the Birmingham Stallions, Oakland Invaders and Tampa Bay Bandits.
The rise and swift fall of the league is the subject of a book by New York Times Bestselling author Jeff Pearlman.
Football For A Buck: The Crazy Rise And Crazier Demise Of The USFL details some of the more outlandish elements of the story and also features the involvement of a certain current President of the United States.
New Jersey Generals owner Donald Trump and other USFL team owners played a role in trying to move the USFL towards an Autumn/Winter schedule that would have attempted to challenge the NFL and bring about a merger.
That episode as well as the tale of the USFL filing an anti-trust lawsuit against the NFL are all featured in Pearlman's book and he joined Nathan Murphy to discuss.
