Well, if the Chiefs somehow lose on Saturday and the Bills win on Sunday, the #1 seed goes to Buffalo, and if I'm reading the resolution correctly, the Bills get the bye and home-field (i.e. no neutral site factoring in). If the Chiefs win and the Bills win, the Bills get the 2, get 2 playoff games at home (assuming they can win both) and then avoid a trip to KC (again, assuming KC also gets that far). I think that is about the best we can hope for as of Monday night with all that has happened.
