I know the Eagles haven't played yet, but even after MNF the Bills will have less points against than the 8-1 Eagles in one less game played. Our defense allows 4.4 less points per game! The Eagles offense only outscores us by 1.3 points per game (and I can see that coming down after the KC game, Chiefs have a great defense).
I'm thinking the Eagles will be able to score on us, but their defense is vulnerable and definitely gives up points this year.
Another interesting stat. The Bills are tied for 2nd in the NFL in takeaways, but still only have a neutral - 0 turnover differential. Yikes!
