The biggest conference championship upsets in NFL history

Nothing is guaranteed in the NFL — not even a trip to the Super Bowl. Here are the most shocking upsets in conference championship history.

This was supposed to be a coronation for Dennis Green’s Vikings. An offense designed by Brian Billick and quarterbacked by Randall Cunningham, with Randy Moss and Cris Carter as its primary receivers, set a then-single season record with 556 points. The only game they’d lost was a 27-24 nailbiter to the Buccaneers. And in the conference championship game, they faced a Falcons team that did go 14-2, and was balanced on both sides of the ball, but was nowhere near as explosive. The Vikings were 11-point favorites, which the Falcons apparently ignored — they busted out to a 7-0 lead, and fought back from deficits of 17-7 and 27-17 to force the game to overtime. Gary Anderson’s missed fourth-quarter field goal assured that, and Morten Andersen’s 38-yard game-winner sent Dan Reeves’ Falcons to Super Bowl XXXIII, where Reeves was outdone by former pupil John Elway in Elway’s last game.
