It's really starting to simplify for the Bills. If they lose to NE, they're more than likely going to be looking at needing either BAL or CIN to lose two of three.
BAL:
@CIN
LAR
PIT
CIN:
BAL
KC
@CLE
That's why this BAL-CIN game this week is so critical. Really need the Ravens to win. Then we would just need the Chiefs to beat the Bengals.
If the Bengals beat the Ravens, I think the Bills will miss the playoffs. CIN will go 2-1 with wins over BAL and @CLE, and BAL will also go 2-1 with home wins over LAR and PIT to close the season.
