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.
Super Bowl
No team has ever played the Super Bowl in its home stadium. The closest any team has come was the 2017 Minnesota Vikings, who were within one win of playing Super Bowl LII in U.S. Bank Stadium, but lost the NFC Championship game to the Philadelphia Eagles. Two teams have played the Super Bowl in their home market: the San Francisco 49ers, who played Super Bowl XIX in Stanford Stadium instead of Candlestick Park; and the Los Angeles Rams, who played Super Bowl XIV in the Rose Bowl instead of the Los Angeles Memorial Coliseum. In both cases, the stadium in which the Super Bowl was held was perceived to be a better stadium for a large, high-profile event than the stadiums the Rams and 49ers were playing in at the time; this situation has not arisen since 1993, in part because the league has traditionally awarded the Super Bowl in modern times to the newest stadiums. Besides those two, the only other Super Bowl venue that was not the home stadium to an NFL team at the time was Rice Stadium in Houston: the Houston Oilers had played there previously, but moved to the Astrodome several years prior to Super Bowl VIII. The Orange Bowl was the only AFL stadium to host a Super Bowl and the only stadium to host consecutive Super Bowls, hosting Super Bowls II and III.
