Professional team that has not won a championship?

Answer 1

There are 13 current NFL teams that have not won a championship since the advent of the Super Bowl (formerly the AFL-NFL Championship Game). These are the Atlanta Falcons, Philadelphia Eagles, Detroit Lions, Cincinnati Bengals, New Orleans Saints, Buffalo Bills, Carolina Panthers, Arizona (formerly St. Louis and Chicago) Cardinals, Houston Texans, Cleveland Browns, Tennessee Titans (formerly Houston Oilers), and Jacksonville Jaguars. Of those 13 teams, Detroit, Philadelphia, Buffalo, Arizona/St Louis/Chicago and Cleveland all won NFL championships before the AFL and NFL merged in 1970. Also, Buffalo and Houston won AFL titles prior to the merger. So the final answer is there are six NFL teams who have not won league championships since their inception. Of those, Carolina, Atlanta and Cincinnati have all won conference championships but failed to win the league championship.
