Football's biggest association was founded in 1920 under the name the AFL. However 44 years later, in 1966, the AFL became the NFL. Less than a year later, the first superbowl was held. 13 teams have never won a superbowl. Out of these 13, 4 of these teams have never even been to the super bowl. The Stealers have won the most superbowls with six superbowl victories.
