The Kansas City Chiefs didn't lose this season until Nov. 17. And that one loss knocked them back into a three-way race for the No. 1 seed in the AFC playoffs.
The Buffalo Bills and Pittsburgh Steelers each have just two losses, one behind Kansas City, and Buffalo has clinched the head-to-head tiebreaker. Buffalo and Pittsburgh also have arguably easier paths than Kansas City the rest of the way.
Kansas City has four games remaining against teams that are .500 or better (Steelers, Chargers, Texans, Broncos).
