That Playoff Machine is great. According to it, if the following happens:
Bills (7-5) beat OAK, go 8-8
Miami (6-5) only beat Jets once, loses all other games, goes 7-9
CLE (7-5) beats BAL Week 17, loses out, goes 8-8
PIT (7-5) beats KC Week 16, loses out, goes 8-8
BAL (7-5) beats MIA Week 14, loses out, goes 8-8
SD (8-4) beats KC Week 17, loses other games, goes 9-7
KC (7-5) loses every game, goes 7-9
HOU (6-6) beats BAL, loses other games, goes 7-9
... Then the Bills will make the playoffs at 8-8!
So, there you have it - no ties necessary and we don't have to beat any top QBs. At least if the playoff machine has calculated tiebreakers correctly.
If the Bills beat Denver, we need a lot less help. But in any case, the rooting guide next week should probably be:
Bills over Denver (obviously)
Indianapolis over Cleveland (definite)
Jacksonville over Houston (definite)
Arizona over Kansas City (definite)
Cinci over Pittsburgh (almost certainly)
Baltimore over Miami (iffy, but probably better)
New England over San Diego (probably better)
