A sports-related curse is a superstitious belief in the effective action of some malevolent power, that is used to explain the failures or misfortunes of specific sports teams, players, or even cities. Teams, players, and cities often cite a "curse" for many negative things, such as their inability to win a sports championship, or unexpected injuries.
American football
Detroit Lions
In 1958, the Detroit Lions traded Bobby Layne to the Pittsburgh Steelers, with Layne responding to the trade by supposedly saying that the Lions would "not win for 50 years". The veracity of this story has been disputed, particularly because the quote was never published at the time.
Despite this, in the 50 years after the trade, the Lions accumulated the worst winning percentage of the 12 teams in the National Football League (NFL) at the time, and are still one of only two franchises that were in the NFL prior to 1966 that have not yet played in the Super Bowl. The Lions' lone playoff win came against the Dallas Cowboys following the 1991 season.
When the Pittsburgh Steelers won their fifth Super Bowl championship in 2006, they won it at Ford Field, the Lions' current home stadium. Two years later – in the last year of the supposed curse – the Steelers won their sixth Super Bowl championship, while the Lions finished 0–16, the first team to lose every game of a 16-game season.
Philadelphia Eagles
This alleged curse supposedly prevented the Philadelphia Eagles franchise from winning the Super Bowl until Super Bowl LII.
The origin of this curse dates back to 1960, when the Eagles defeated the Vince Lombardi-coached Green Bay Packers to win the NFL Championship, which would be the only playoff loss in Lombardi's coaching career.
Following Lombardi's death in 1970, the League named the Super Bowl trophy in honor of his memory and his legacy.
This renaming of the trophy, combined with the Eagles' failures to win another Championship after 1960, led some Eagles fans to believe the franchise was cursed by Vince Lombardi: that being the only team to beat Lombardi in a playoff game meant never winning the trophy named after him.
During that time, the Eagles accumulated playoff heartbreaks that included two Super Bowl losses (to the then Oakland Raiders and New England Patriots), and three consecutive NFC Championship Game losses in 2001, 2002, and 2003.
The curse was broken in 2017 when the Eagles defeated the Patriots in Super Bowl LII to win their first Championship in 57 years – by coincidence, the Eagles' Championship drought lasted the same length as Lombardi's life.
Madden NFL
Prior to 1999, every annual installment of the Madden NFL video game franchise primarily featured John Madden on its cover. In 1999, Electronic Arts selected San Francisco 49ers running back Garrison Hearst to appear on the PAL version's cover, and has since featured one of the league's top players on every annual installment despite Madden's opposition. While appearing on the cover has become an honor akin to appearing on the Wheaties box, much like the Sports Illustrated cover jinx, certain players who appeared on the Madden video game box art have experienced a decline in performance, usually due to an injury.
Super Bowl
The Super Bowl curse or Super Bowl hangover is a phrase referring to one of two things that occur in the National Football League (NFL): Super Bowl participant clubs that follow up with lower-than-expected performance the following year, and NFL teams that do not repeat as Super Bowl champions.
