Chiefs D I tend to stay away from because they get involved in a lot of shootouts, rank 28th in opposing points per game. Their offense is geared to score quickly, so even if the defense starts off well, it wears down--good example is the Chargers game.
Dolphins seem obvious but after basically losing their playoff hopes, I question how much effort they will give.
Colts entice me because they play a lot of zone defense (more than about any other team) and i've read about Eli struggling against zone coverage. Plus, unlike Miami, they will give solid effort.
