If the Saints beat the Steelers, it would send them down to third place in the AFC North.
If the Browns lose to the Bills, it would send them down to last place in the AFC North (Pittsburgh has the better conference record as they are 6-3 in conference play, while the Browns are 4-4 in conference play).
The Dolphins are currently in 10th place in the AFC. A loss to the Jets would put them far back in the running. Even better would be if the Dolphins lost a physical matchup, which would leave them very exhausted for the Ravens game against them in Week 17. J-E-T-S! Jets! Jets! Jets!
