The biggest upset in Super Bowl history remains the New York Jets' triumph over the Baltimore Colts in Super Bowl III after Joe Namath guaranteed the Jets would pull the upset. New York's 16-7 win marked the first time an NFL team lost a Super Bowl and provided needed legitimacy to the upcoming AFL-NFL merger.

Tom Brady's historic run also began with a massive upset as the Patriots shocked the Greatest Show on Turf with an Adam Vinatieri walk-off field goal in Super Bowl XXXVI. The game ended a potential dynasty for the Rams and set New England off to become the league's most dominant franchise for two decades.

It may surprise some to see the New York Giants' shocking win to deny the Patriots a chance at perfection in Super Bowl XLII third on the list but the lien for that game locked in at 12.5 points. Perhaps New York's stirring performance in the regular season finale against New England lowered the spread but this upset may be second in magnitude only to the Jets-Colts Super Bowl III affair.

The Chiefs added another big upset to the AFL's ledger when they blew out the Minnesota Vikings in Super Bowl IV despite opening as 12-point underdogs. That win was the final one before the AFL and NFL merged, ensuring the AFL-NFL era ended with two Super Bowls for each league.

Another memorable upset came in Super Bowl XXXII, when the reigning champion Green Bay Packers were shocked by the Denver Broncos 31-24. The win allowed Denver to ensure future Hall-of-Famer John Elway would be able to retire with at least one Super Bowl win.
