That depends on which games the 3 teams lose. The tiebreakers are not yet set in stone. If either Pittsburgh or Cleveland win their remaining NFC games but end up 9-8, and the Bills lose to the Cowboys and Eagles, the Bilss would win conference record tiebreakers against those two teams.
Houston's a little trickier, they'd have to win their remaining NFC game, the Bills would have to lose to the Cowboys and Eagles, and there'd have to be 3rd AFC team in the tiebreaker with the same conference record to avoid common games and go directly to strength of victory.
There are no teams the Bills can't win a tiebreaker against right now - even the teams that beat them could get into a multiple team tiebreaker and fall below them before the H2H win registers
For example: Here's one giant ass 9-8 log jam that the Bills actually get out of the tiebreaker first:
Playoff Predictors
Their strength of victory is actually assured to be pretty good at 9-8 so their multiple team tiebreakers are actually going to be excellent if 2 of their remaining losses are to the NFC teams (which isn't exactly out of the question). You can't just enter in one scenario into the playoff machine and say "well, this is how the tiebreakers land". It's too dependant on WHICH remaining games are won and lost.
This is also going to create some strange rooting scenarios in the coming weeks. For example: we are going to want the Chargers to WIN against the Packers Sunday. They are a prime candidate to be one of those 9-8 teams that can cancel out either Cincy/Jacksonville's H2H win (if Houston catches JAX) OR Houston's common opponent advantage. And since we play the Chargers later we can land one of those losses they need. A Chargers loss, however, would guarantee they have a better conference record than us at 9-8, which means they would be guaranteed to get out of a 3 team tiebreaker before us, meaning we would still be hampered by H2H losses to Cincy/Jacksonville or common opponent deficits to Houston.
