Two weeks is a loooooong wait, but if the opening line doesn't move between now and Feb. 4, the Eagles will be the biggest Super Bowl underdog in nearly a decade.

The Eagles open as 5½-point underdogs against the Patriots, according to Bovada. No team has been a bigger Super Bowl underdog since the Cardinals, who were 7-point dogs against the Steelers after the 2008 season.

The line could move, though. It already has, in a way. Last week, Bovada's pre-championship weekend odds pegged the Eagles at plus-7 if they were to face the Patriots in the Super Bowl.

If you got your money in on the Eagles last spring, you're loving life right now. The Birds were 50/1 to win the Super Bowl until the season began, and they were 40/1 as late as Week 3.
