2017 @ Jax (awful game, not affected by the road venue IMO, but I think the Bills win it at home due to how close it was)
2019 @ Houston (does that 2nd half unfold the way it did at home, maybe not)
2020 @ KC (stomped, almost certainly lose at home)
2021 @ KC (I'm convinced the Bills win at home)
So I'll give you two of those, 1 maybe, and one no.
