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.
History of the Dallas Cowboys
In 1966, the Cowboys posted their first winning season, finishing atop the Eastern Conference with a 10-3-1 record. Dallas sent eight players to the Pro Bowl, including Howley, Meredith, Perkins, and future Pro Football Hall of Fame members Hayes, Lilly, and Renfro. In their first-ever postseason appearance, the Cowboys faced the Green Bay Packers in the 1966 NFL Championship Game, with a trip to the first ever Super Bowl on the line. Green Bay defeated Dallas in a 34–27 thriller by stopping the Cowboys on a goal line stand with 28 seconds remaining and went on to win Super Bowl I 35-10 against the Kansas City Chiefs. Despite this disappointment, 1966 marked the start of an NFL-record-setting eight consecutive postseason appearances for the Cowboys. (Dallas later broke its own record with nine consecutive trips to the playoffs between 1975 and 1983, a record that was tied by the Indianapolis Colts when they reached the playoffs every year from 2002 to 2010, inclusive.) It was also the beginning of a still NFL record streak of 20 consecutive winning seasons that extended through 1985.
