Minnesota....The Vikings won a league championship in 1969 but have lost all four of their Super Bowl appearances since the AFL-NFL merger. Since 1978. The Buffalo Bills nearly had a dynasty in the 1990s, but they found a way to lose in four consecutive Super Bowl appearances. The Panthers lost to the Patriots 32-29 in Super Bowl XXXVIII, then lost to the Broncos 14 years later, 24-10, in Super Bowl 50. The Cincinnati Bengals reached the Super Bowl in 1981 and 1988, losing to the San Francisco 49ers each time.
