5. Buffalo Bills (4-0)
Week 5 ranking: 5
Biggest weakness: Pass defense
Death, taxes and an elite Bills pass defense. Those are the absolute truths we have become accustomed to over the past two seasons, when Buffalo finished fourth and first, respectively, in passing yards allowed. In typical 2020 fashion, the Bills are polar opposites from their previous selves in that regard, allowing the fourth-most passing yards per game through four games this season. They have battled injuries in both the secondary and at linebacker, neither of which have helped their case; fortunately for Leslie Frazier's unit, Buffalo's offense has proved more than capable of winning a shootout. -- Marcel Louis-Jacques
