For those of you holding out hope...
Week 14: Bills beat Steelers, Pats beat Ravens, Titans beat Broncos
Week 15: Bills beat Browns, Pats beat Broncos, Chiefs beat Titans
Week 16: Bills beat Dolphins, Steelers beat Ravens, Chiefs beat Broncos
Week 17: Bills beat Jets
If all of those happen, and if the Dolphins don't beat the Cardinals, Patriots and Jets (in other words, just lose one of those three games), then we're in.
Other than the Bills beating the Steelers, many of those outcomes are realistic. So I think the intent of the original post was, just figure out a way to win Sunday and you can see a path to the playoffs.
