17. The New England Patriots appeared in the most Super Bowls
New England, which played in the old AFL as the Boston Patriots, appeared in eleven Super Bowls, winning six. They are tied for the most wins with the Pittsburgh Steelers, who appeared in eight games, losing twice. The team which appeared in the most consecutive Super Bowls, the Buffalo Bills, suffered the unfortunate circumstance of losing them all. No team has ever won three in a row, though seven teams have achieved back-to-back wins. The Steelers are the only team to have done so twice. The only teams to have appeared in multiple Super Bowls without losing one are the Baltimore Ravens.
Numerous teams have gone many years without a Super Bowl appearance, let alone a victory. The New York Jets won the 1968 game and have yet to be back. The Buffalo Bills appeared in their fourth consecutive Super Bowl in January, 1994, and have failed to return since. Four NFL teams have never appeared in the Super Bowl, including the Cleveland Browns, which suspended play in 1995 when the team moved to Baltimore as the Ravens. The Browns returned to NFL play in 1999. The Detroit Lions, Jacksonville Jaguars, and Houston Texans have also never appeared in a Super Bowl.
