The last team to win back-to-back Super Bowl championship was the 2003-04 New England Patriots.
And the percentages say the Philadelphia Eagles won't end that drought this season.
FiveThirtyEight, the major statistical website, put out its 2018 NFL projections on Wednesday evening and the Eagles actually logged the second-best odds to win Super Bowl 53. But the odds are still remarkably slim.
According to FiveThirtyEight, the Eagles have just a 12-percent chance of repeating as champions.
But here's the good news for Eagles fans: the team also has a 76-percent shot at reaching the playoffs and a 40-percent chance of grabbing a first-round bye.
