My money is on the Lions or Cardinals. My gut is saying the Cardinals.

have to be the Bills I would guess

I would guess the Saints or the Cardinals (although they did have a decent team mid-'70s).

I think the Lions.

Cheers!

Arizona Cardinals,the team has not won a league title nor played in the championship game since then, and thus currently holds the NFL record for the longest championship drought and along with the Houston Texans (founded in 2002) are the only team not to appear in a conference championship game. The team has also won only two division titles (1974 and 1975) since their 1947 NFL championship. Despite being the oldest existing professional football franchise in the United States, the Cardinals have a remarkably lean postseason history, with an all-time record of 2-5, 456 Wins, 659 Losses, 39Ties(1920-2006, regular season)
