NFL Odds: Super Bowl Betting Trends

Underdogs have been on a run in the Super Bowl, and the Seattle Seahawks certainly look like a live betting dog this year.

Underdogs have covered the spread in five of the last six Super Bowls, winning four of six outright. The Baltimore Ravens, New Orleans Saints, and New York Giants have pulled off straight-up Super Bowl upsets.

The Giants did it twice, beating the favored New England Patriots in 2012 and 2008. The Arizona Cardinals covered as 7-point underdogs in a 27-23 loss to the Pittsburgh Steelers.

The Green Bay Packers in 2011 are the only favorites to win and cover since 2007, when Peyton Manning and the Indianapolis Colts won and covered in a 29-17 win over the Chicago Bears in Super Bowl XLI. The Ravens’ win over the 49ers last season broke a run of five straight Super Bowl covers by the NFC.

Manning is back in the Super Bowl for a third time; he’s leading the Denver Broncos this time. The Broncos are the only team to be favored in every game this season. They’ve excelled in the role of favorites, going 9-2 straight-up and 8-3 against the spread in their last 11 games as the chalk.

Some sports books, like 5Dimes, opened the Super Bowl point spread as a pick ‘em. Heavy early action came in on the Broncos, who could be found as high as 3-point favorites early in the week.

The Seahawks have thrived in the underdog role under coach Pete Carroll. Seattle is 8-2 against the spread in their last 10 games as underdogs and 17-5-1 as dogs over the last three seasons. The Seahawks were only underdogs once this season - they covered as short dogs in a 19-17 loss at San Francisco in early December.

So much attention is paid to the Seahawks’ success at home at noisy CenturyLink Field, but they haven’t been bad away from home, either. They’ve covered the spread in nine of their last 11 away games.
