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 XXIV
After Super Bowl XXIV, Elway and the Broncos entered a period of decline. 1990 saw them fall to 5-11, which put them last in the AFC West. While they returned to the playoffs in 1991, the Broncos failed to make the Super Bowl after losing the AFC Championship Game to the Buffalo Bills. That marked the first time in their existence that Denver lost the conference championship. They eventually returned to success as Elway led the team to an NFL-best 13-3 record in 1996, only to lose in their first playoff game against the Jacksonville Jaguars. Incidentally, that was the final time in Elway's career that he would lose a playoff game. After his three previous attempts had gone unsuccessfully, Elway led the Broncos to Super Bowl XXXII where they finally broke through and won the Super Bowl for the first time in franchise history over the Green Bay Packers. A year later, in what later proved to be the final game of his career, Elway led the Broncos to another victory in the Super Bowl as Denver won Super Bowl XXXIII 34-19 over the Atlanta Falcons.
