Sports-related curses
The Buffalo sports curse is an explanation for Buffalo's inability to win a Super Bowl, Stanley Cup, or an NBA championship. Those who believe in the Buffalo curse cite as examples the four consecutive Super Bowl losses by the Buffalo Bills for the 1990–1993 seasons (and the team's failure to qualify for the NFL playoffs from 2000 to 2017), as well as the failure of the Buffalo Sabres ever to win the Stanley Cup (despite winning the Presidents' Trophy for most regular-season points in 2006–07). The Bills, however, won two American Football League (AFL) titles (1964 and 1965), the latter occurring just months before an agreement was reached to merge the AFL and the National Football League (NFL) (Bills owner Ralph Wilson initiated the talks to merge the two leagues, according to the Pro Football Hall of Fame). In spite of that, it has been argued that this was achieved when the AFL was in its infancy as an upstart league, garnering little, if any, national attention before merging with the established NFL, and that even if they are considered to be at par, since there would be no Super Bowl until after the 1966 season, the Bills could be no greater than co-champions. There have been conflicting suggestions on how the Bills would have fared against the Green Bay Packers or Cleveland Browns, much as there have been disputes over how well the San Diego Chargers would have played against the Bears in 1963, had the Super Bowl existed at that time.
New Orleans Saints
The 2009 season was a historic one for the Saints. Winning a franchise-record 13 games, they qualified for Super Bowl XLIV and defeated the AFC champion Indianapolis Colts 31–17. To date, it is the only Super Bowl championship that they have won, and as it is the only Super Bowl the Saints have appeared in, they join the New York Jets and Tampa Bay Buccaneers as the only three NFL teams to win their lone Super Bowl appearance.
