The Chiefs can still win the AFC West depending on how they finish along with the Broncos, who are 10-4 on the season. The Chiefs will likely need to win next week against the Raiders to have a shot at the division. And they will need a loss from the Broncos either on Monday night against the Bengals or in Week 17 against the Chargers. Considering the quality of the opponent, Monday Night Football is the best chance to see the Broncos lose. They will host the Bengals tonight.
In other words...
Gotta rest up. My Bengals have a big game tonight. Who dey, @CincyJungle— Arrowhead Pride (@ArrowheadPride) December 28, 2015
There's also the scenario where the Chiefs lose AND the Broncos lose both of their remaining games. That would also give the Chiefs the AFC West title.
The bottomline is that the 10-5 Chiefs need to finish with the same record as the 10-4 Broncos because the Chiefs own the key tiebreakers. The Chiefs will either be a Wild Card as the No. 5 or No. 6 seed and go on the road on Wild Card weekend or be the No. 3 or 4 seed and host a home playoff game.
