If you're not putting money on the Patriots, you're putting money on the Birds. And if you're not - you've not followed the NFL this season.
The Patriots and the Eagles are easily the top 2 teams in the league through 11 games. Perhaps the Eagles are a couple points favorites currently given their defense. Otherwise it would be evenly matched.
That means nothing going into the postseason, however. Once the playoffs start - every game is a toughie, even for the best teams.
It'll be interesting to see how it unfolds. There is no team in the NFC closer to the Eagles than Pittsburgh is to New England in the AFC. Yet that still matters very little, outside of home field advantage.
