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 III
The Baltimore Colts had won the 1958 and 1959 NFL championships under Coach Weeb Ewbank. In the following years, however, the Colts failed to make the playoffs, and the Colts dismissed Ewbank after a 7–7 record in 1962. He was soon hired by New York's new AFL franchise, which had just changed its name from the Titans to the Jets. In Ewbank's place, Baltimore hired an untested young head coach, Don Shula, who would also go on to become one of the game's greatest coaches. The Colts did well under Shula, despite losing to the Cleveland Browns in the 1964 NFL Championship Game and, in 1965, losing in overtime to the Green Bay Packers in a tie-breaking game to decide the NFL Western Division championship. The Colts finished a distant second in the West to the Packers in 1966, and in 1967, with the NFL divided into four divisions of four teams each, went undefeated with two ties through their first 13 games, but lost the game and the Coastal Division championship to the Los Angeles Rams on the final Sunday of the season—under newly instituted tiebreakers procedures, L.A. won the division championship as it had better net points in the two games the teams played (the Rams win and an earlier tie). The Colts finished 11–1–2, out of the playoffs. In 1968, Shula and the Colts were considered a favorite to win the NFL championship again, which carried with it an automatic berth what was now becoming popularly known as the "Super Bowl" against the champion of the younger AFL. The NFL champion, in both cases the Green Bay Packers, had easily won the first two Super Bowls (1967 and 1968) over the AFL winner, establishing for a while then the superiority of the older NFL circuit.
