Other than a few anomalies (noted below), the AFC comes down the the Ravens, Bengals and Dolphins fighting for the last 2 playoff spots. Because the Bengals and Ravens play each other in week 17, each can make the playoffs by winning their last 2 games.
2-0: Will get in if they win their last 2 because they will either have a better record than the Ravens or the tie-breaker over the Bengals, depending on who wins in week 17.
1-1: Would get in if either the Bengals or Ravens lose their last 2.
Bengals and Ravens
Bengals can clinch the division this week with a win over the Vikings and a Ravens loss to the Patriots. Otherwise, the winner of the Ravens @ Bengals game in week 17 will win the division.
1-1: If either team wins this week but loses week 17, they would still be the wildcard if the Dolphins lose at least 1 game. Out if the Dolphins go 2-0.
0-2: both teams could still back into the playoffs if the Dolphins also go 0-2. The Ravens would also need to Chargers to lose at least 1 game.
**For the 2nd week in a row, the Bengals can gain some ground on someone with a win. They would clinch the division if the Patriots beat the Ravens or move into the #2 seed if the Ravens beat the Patriots.
6-game parlay: get the 2nd wildcard if they win out and the Dolphins and Ravens both lose out.
Need every NFL team and several NBA teams to lose out.
I know that there's a way for the Steelers to get in but I'm too lazy to look it up. They obviously need to win out, have the Dolphins and Ravens both lose out and the Chargers lose at least 1, possibly 2. I think the Jets also need to win both of their games. I don't know.
Dolphins win the East
Dolphins win out and the Patriots lose out. They split the season series. Dolphins would win the division on either common games or conference record, I'm not sure which (see above - lazy).
Birds, Cats and Fish*
6-game parlay: Ravens, Bengals and Dolphins could all make the playoffs with the Patriots missing out only if:
Patriots go 0-2
Dolphins go 2-0
Bengals beat the Vikings and lose to the Ravens (who would have beaten the Patriots in week 16)
That would make all 4 teams 10-6. Dolphins win the East (see above). Ravens win the North (keep seeing above). Bengals win head to head tie-breaker over the Patriots.
Colts have won the division, everyone else is out. Colts are currently the #4 seed (lost to the Bengals) but could move as high as #1 (they beat the Broncos) with help (lots of it).
Broncos and Chiefs are both 11-3 but the Broncos swept the Chiefs. The Chiefs can win the division by gaining 1 game but the Broncos play the Texans and Raiders (combined 6-22).
