Browns!
NEVER..............
There are only 4 who haven't been to the super bowl. Cleveland Browns, Detroit Lions, Houston Texans, and the Jacksonville Jaguars. The New Orleans Saints and the Arizona Cardinals each made their first appearance in the Super Bowl the last two seasons. The Saints won in 2010, and the Cardinals lost on a last minute touchdown in 2009.
As of 2010, it is Houston, Texas.
Super Bowls played in Houston Texas:Super Bowl XLIX, NRG Stadium, 2/5/2017Super Bowl XXXVIII, Reliant Stadium, 2/1/2004Super Bowl VIII, Rice Stadium, 1/13/1974
As a Houston Texans fan myself, I unfortunately have to say that they have never been to the Super Bowl. Although, they have been to the playoffs on a few occasions (three to be exact). The first was in 2011, when they lost in the Divisional Round to the Baltimore Ravens. The second was the year after in 2012, when they lost in the Divisional Round again, but this time to the New England Patriots. The last time was last year (2015), and they lost in the Wild Card Round to the Kansas City Chiefs.
