As the defending champions, it is understandable that the Patriots are Superbowl betting favorites, and the fact that the Eagles don’t have their starting quarterback only hurts their odds.

The Eagles are the largest Super Bowl underdog since the Arizona Cardinals were seven-point underdogs to the Pittsburgh Steelers in Super Bowl XLIII.

Philadelphia has been an underdog all season long. The Eagles were 40-1 to win the Super Bowl at the beginning of the season. They started the season 10-2 but lost quarterback Carson Wentz to a knee injury in early December. Backup quarterback Nick Foles stepped in and led the Eagles to back-to-back wins in the playoffs. Despite finishing the season with better records than their opponents, the Eagles were underdogs in each of their playoff games, against the Atlanta Falcons and the Vikings.

After winning the Super Bowl last season, the Patriots started the season as the consensus Super Bowl favorites with odds around 5-2 and, after a few early losses, they remained the team to beat at Las Vegas sportsbooks for the majority of the season.

Interestingly, the Westgate SuperBook noted that if Wentz wasn’t injured, the odds for the Super Bowl would have been pick’em, which is surprising because the bookmakers usually show the Patriots love.

In the last 51 years, the betting favorite has won 33 of the previous 51 Super Bowls, with the Patriots owning two of those losses thanks to Eli Manning and the New York Giants.
