The Kansas City Chiefs dominated the Denver Broncos for the second time this season on Sunday, beating them 23-3 in a blizzard at Arrowhead Stadium. The win extended their dominance over the AFC West, improving their division record to 5-0 and completing their fourth straight season sweep over the Broncos. While KC’s divisional dominance has been clear for a few weeks now, their standing as a true Super Bowl contender has been a little questionable as the Chiefs have often failed to put together impressive outings on both offense and defense. That wasn’t the case on Sunday and it should have the rest of the AFC playoff teams nervous about having to face the Chiefs in January.
