Underdogs have covered the Super Bowl point spread in 8 of the past 11 games, but the history of Super Bowl betting is marked by plenty of big blowouts as well.
The biggest Super Bowl spreads in history saw one team easily cover 18.5 points (the 49ers blew out the Chargers at Super Bowl XXIX) and one team lose outright in the biggest upset in Super Bowl history (Joe Namath’s guaranteed win by the Jets over the Colts as 18-point dogs at Super Bowl III).

Interestingly, the past two times the Super Bowl saw a double-digit favorite, the underdog won outright each time in a huge upset. The Patriots were victimized by the Giants four years ago as 12-point chalk after earlier beating the Rams as 14-point underdogs back at Super Bowl XXXVI.
