There are 12 teams that have never won a super bowl. These teams are: Titans, Chargers, Vikings, Jaguars, Texans, Lions, Browns, Bengals, Panthers, Bills, Falcons and Cardinals
The teams that have the best chance this year are the Bills and Titans because they are in the playoffs and will most likely win their first round matchups. The Browns made the playoffs but they have no chance of beating the Steelers Sunday Night.
The teams with the worst chance to win next year are the Falcons and Texans. They may never win in my lifetime, they are awful organizations, but I can see the Jaguars winning a Super Bowl before both of those teams!
