MetLife Stadium in New Jersey, which hosted Super Bowl XLVIII, is the home stadium of two NFL teams: the New York Giants and the New York Jets. This list of examples is not exhaustive; no team has ever qualified for the Super Bowl played in their home stadium. Since 1993, few winning teams have followed up their Super Bowl appearances with a second Super Bowl appearance, or even advanced to a conference title game in the subsequent season (the 1994 Dallas Cowboys qualified for their conference title but did not qualify for the Super Bowl). Only seven teams have won back-to-back Super Bowl championships, and only one of these seven have made more than two consecutive winning appearances in the Super Bowl. The only franchise to reach more than three straight title games was the Buffalo Bills who lost four Super Bowls in a row from 1990–93. The salary cap, draft, free agency and the schedule makes it more difficult to win repeat league championships in the NFL, compared to other major North American professional sports leagues (MLB, NBA, and NHL) where dynasties have been prevalent. Since 2005, no incumbent holder has managed to successfully defend their title. Between 2006 and 2013, every defending Super Bowl champion would conclude the following season either losing their opening playoff game or failing to qualify for the playoffs. This list of examples includes every team that has ever had back-to-back appearances at the Super Bowl. Although many teams experience this phenomenon, it is certainly not the rule. There are many speculations made about potential causal factors for this trend, including the team having a shorter offseason due to their extended postseason play, difficulty settling contracts, more pressure on the players, and an increase in visibility, which could contribute to nervous playing. Only the 1971 Dallas Cowboys, 1972 Miami Dolphins, and 2018 New England Patriots have followed up a Super Bowl defeat with Super Bowl win the following season. One piece of the Super Bowl curse asserts the team that loses the Super Bowl will go into losing seasons overall. The trend was especially evident during the early 2000s. This list of examples is not exhaustive.
