I'd like to see the different scenarios you have in mind.
If the Jets lose 2 (mia plus another) Mia loses one, and Pats lose one. Dolphins will most likely win the division.
Under that situation the:
Mia would be 10-6; Pats would be 10-6; Jets would be 9-7; Bills at best would be 9-7.
Tie breakers between Pats and Dolphins:
1. Head-to-head (best won-lost-tied percentage in games between the clubs).
split
2. Best won-lost-tied percentage in games played within the division.
if the Pats lost was to the Bills than Mia would win on this tie breaker
3. Best won-lost-tied percentage in common games.
Under any situation where the teams are tied, the Pats and Mia tie here too.
4. Best won-lost-tied percentage in games played within the conference.
right now Mia is 6-4; Pats are 5-5. each have two conf games left to play:
Pats - Bills and Oak; Mia - Jets and KC.
We have already taken care of Pats lose to Bills with tie breaker #2. If the Pats lose to Oak even if Mia was to lose to KC. Mia would win this tie breaker. But if Mia was to lose to KC and NE was to lose to AZ then this tie breaker would be even at 7-5.
So the only way we get to tie breaker number 5 is MIA beats Jets and SF lose to KC; Pats beat Bills and Oak lose to AZ.
5. Strength of victory.
The only non-common victory would be
NE beating KC
Fish beating SD.
KC is currently 2-11; SD 5-8. In order for MIA not to win this tie breaker SD would have to lose all remaining games and KC would have to win all remaining games. If that happens this tie breaker is even.
6. Strength of schedule.
Only two non-common games
Pats - Colts (9-4) and Steelers (10-3)
Fins - Ravens (9-4) and Texans (6-7)
NE is currently leading in this tie breaker but Fins could pass them.
-------
The only realistic way Mia doesn't win the tie breakers assuming the teams end with a tied record at the end of the season would be if, MIA was to lose to the Jets. And even then if Pats and Mia end 10-6 with the Jets 9-5, Mia would win the tie breakers if the Pats loss was to the Bills.
