KC and Baltimore are going to win their divisions and 5 more playoff spots, 2 division winners and 3 wild cards
If Miami beats Dallas and Baltimore and loses to Buffalo they have 12 wins, unlikely they win 2 of last 3.
Cleveland has Houston, NYJ and Cincy, 2 wins and a loss to Cincy gives them 11 wins and 8 conference wins
Cincy has Pitt, KC and Cleveland, 3 wins gives them 11 wins and head to head vs Buffalo
Jax has Tampa, Carolina and Tenessee, 3 wins gives them 11 wins and head to head vs Buffalo
Indy has Atlanta, Las Vegas and Houston, 3 wins gives them 11 wins and 9 conference wins
Houston has Cleveland, Tennessee and Indy, I see 2 losses there so they are out
Buffalo wins out with 11 wins and 7 conference wins and is out in this scenerio
If any of Indy, Jax or Cincy lose 1 and Cleveland and Miami need to lose 2 then Buffalo jumps them if Buffalo wins out.
I can see Jax and Indy winning 3 each and Cleveland winning 2, that leaves Buffalo needing Cincy to lose 1 and Miami to lose 2, I can see that happening.
Buffalo vs Miami could be for the division winner is in and loser is out.
I'm sure there are more scenarios out there don't have time to research all of them.
Bottom line is Buffalo needs to win out and they still might not make it
