The Super Bowl curse is a phrase coined to explain why Super Bowl participants follow up with lower than expected performance the following year. Also called Super Bowl hangover, it has been utilized to explain both why losing teams may post below-average winning percentages in the following year and why Super Bowl champions seldom return to the Super Bowl the following year. The term has been utilized at least since 1992, when The Washington Post commented that "[t]he Super Bowl Curse has thrown everything it's got at the Washington Redskins. The Jinx that has bedelived defending champs for 15 years has never been in better form". The phenomenon is attributed by football commentator and former NFL manager Charley Casserly to such elements as "a shorter offseason, contract issues, [and] more demand for your players' time". Casserly also notes that "once the season starts, you become the biggest game on everybody's schedule."
