Upon further review...
I have KC and Tenn winning out
NE, Hou, Pitt, LC and Denver losing 1 more
Balt and Miami losing 2 more
Indy losing 3 more
That leaves...
1 - KC (14-2)
2 - NE (12-4)
3 - Hou (12-4)
4 - Pitt (10-5-1)
5 - LAC (12-4)
6 - Ten (10-6)
Bal, Ind, Den at 9-7
Mia at 8-8
This will set up rematches with Ten at Hou and LAC at Pitt (because of the ridiculous division setup and in spite of the Chargers better record and win over Pitt, this game will be a home game for Pitt). Houston and Pitt will go on to win.
That leaves Pitt at KC and Hou at NE, with both home teams winning, resulting in a NE at KC title game in the AFC.
Some games may end up being meaningless and change things...
Hou vs Phi, LAC at Den and Ind at Tenn for instance.
