Was Super Bowl III greatest playoff upset?

Six Super Bowls top this list of the biggest postseason upsets in NFL history, including the top spot. But which game was it?

Was it Super Bowl XXXII, when Broncos QB John Elway finally won the big one? The Giants dealing the Bills the first of four losses in Super Bowl XXV? Lenny Dawson leading the Chiefs over the Vikings in Super Bowl IV? The birth of the Patriots dynasty in Super Bowl XXXVI?

This race seems to come down to two games — the Giants’ upset of the Patriots in Super Bowl XLII, or the Jets over the Colts in Super Bowl III.

The Patriots were undefeated and expected to roll in that game, especially after dismissing the Giants in Week 17 of the 2007 season. But the Jets gave legitimacy to the American Football League and cemented the merger between the two leagues with their win. Tough call.
