If the Bills can win this week, I think there is a good chance that they come out of the bye in a 4 or 5-way tie between all of the wild card teams at 7-5.
Broncos, Bengals, Bills, Colts, Steelers, Jags, Dolphins and Browns all have feasible paths to 7-5 without big upsets required (Jets over Miami, Bengals over Jags, Bills over Eagles, Rams over Browns being the biggest upsets to get those teams to 7-5).
Crowded field this year.
