Buffalo Bills

One of the NFL's loveable losers, they were founded in 1960 as a member of the AFL, winning 2 championships in the league in 1964 and '65. Made the playoffs just one time in the 1970s, despite having OJ Simpson at running back. Were an excellent team from the late 1980s to the late 1990s, with 10 playoff berths in 12 years. These teams were led by 2 hall of famers who never won a championship- quarterback Jim Kelly and coach Marv Levy. Buffalo went to 4 straight Super Bowls from 1990-93, losing everyone. The first was lost on a missed field goal by Scott Norwood. The Bills have not made the playoffs since 1999, despite assembling some talented players in recent years.
