There are 12 teams that have never won a Super Bowl: the Vikings, Bills, Bengals, Falcons, Panthers, Cardinals, Titans, Chargers, Browns, Lions, Jaguars, and Texans.
The Jets haven't won since the 1968 season. For the Dolphins it's 1973. Teams like the Raiders and Bears haven't won since the 1980s. Even rock-solid franchises like the Packers and Steelers have gone more than 10 years since their last championship.
You probably know a fan of one of those teams (or are one yourself). Give them a call and ask a simple question: Would you trade a few years of absolute misery for one Super Bowl title?
