Chicago Fire (1981)
The 1981 Chicago Fire of the American Football Association were a low-budget re-boot of the 1974 Chicago Fire of the World Football League. Both teams used the same logo and colors and played at Soldier Field. But while the WFL aspired to challenge the National Football League for talent and attention, the American Football Association was an avowedly minor league operation. Like the original Fire of 1974, the new Fire of 1981 folded after only one season of play.
