This whole scenario is likely not even possible. They Very likely playoff seeding will have Buffalo as 5th seed and NE 1st. KC probably 2nd seed. For Buffalo to get through the Wildcard they would have to beat the 4th Seed, toss up between West and South right now. That would make Buffalo the lowest ranking seed to make the second round unless the 6th seed pulls off an upset and wins too. NE by default plays the lowest remaining seed in round 2, which if my scenario plays out would be Buffalo. So AFC Championship would not include Bills and Patriots, Divisional round is much more likely at this point. Even if Buffalo Finished 1st and NE 5th.
