The Philadelphia Eagles will enter Super Bowl 52 as the biggest underdogs for the game since 2009, according to several Las Vegas oddsmakers.
The Westgate SuperBook in Las Vegas opened with the Eagles as 5.5-point underdogs to the New England Patriots, which other sportsbooks had the spread closer to six.
The over/under for the Super Bowl is 47.5 points.
The Eagles' spread is the biggest since Super Bowl XLIII, where the Arizona Cardinals were touchdown underdogs to the Pittsburgh Steelers.
