The 5-5 Chiefs are riding a 4-game winning streak that has seen them beat:
the Steelers 23-13
the Lions 45-10
the Broncos 29-13
and the Chargers 33-3
Their remaining games are
Buffalo
@ Oakland
San Diego
@ Baltimore
Cleveland
Oakland
They haven't allowed 20 points in a game since Week 4.
The AFC is pretty weak this year.
The Broncos will head to the playoffs with a highly unproven QB in Osweiler.
The Steelers have the firepower to bang with anybody, but have to ride the old legs of DeAngelo Williams and injury prone Ben Roethlisberger.
And the Bengals are a strong 8-2, but their running game is suspect and losses to the Texans and Cardinals are exposing some flaws.
Granted, nobody is going to take Alex Smith to beat Tom Brady in January. But a team that plays great defense, runs the football, and dominates Time of Possession (3rd in the AFC) could be something to watch.
