Like I said, once they agree with cancelling the Bengals game, they know the possible consequences of that. If KAN wins on Saturday then there's a chance Buffalo rest starters on Sunday. Although, ironically, that could force them back to Cincinnati in the divisional round. If I'm Buffalo then I play Sunday to win regardless of the outcome of the KAN game. Obviously if KAN loses then there's considerable motivation for them to beat NWE. Even if KAN wins then Buffalo still potentially has a much easier path with the #2 seed.
