For a divisional opponent to sweep the Patriots, they'll first have to get past the league and the refs.I think NE will go...
2-4 in division (sweep by Bills)
3-1 vs AFC West (lose to KC)
2-2 vs NFC West (lose to SF/Seattle)
1-1 vs 1st place(beat Houston)
That's an 8-8 record, which may actually be good enough for a wild card. I think Pit/Bal, Ind/Ten occupy the first two and then it's between them, Denver, and Cleveland.
