Have the Buffalo Bills ever won a Super Bowl?
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.
Tampa Bay Buccaneers
The Buccaneers are the first post-merger expansion team to win a division title, win a playoff game, and to host and play in a conference championship game; all three accomplishments occurred during the 1979 season. They are also the first team since the merger to complete a winning season when starting 10 or more rookies, which happened in the 2010 season. In 1976 and 1977, the Buccaneers lost their first 26 games. They would not win their first game in franchise history until Week 13, of 14, in 1977. After a brief winning era in the late 1970s and early 1980s, the team suffered through 14 consecutive losing seasons. Then, for a 10-year period, they were consistent playoff contenders and won Super Bowl XXXVII at the end of the 2002 season, but have not yet returned to the Super Bowl; thus the Bucs, along with the New Orleans Saints and New York Jets, are the only NFL teams to win their lone Super Bowl appearance.
