The Kansas City Chiefs have won just about every way imaginable during a perfect 15-game run that dates to last season: Patrick Mahomes leading last-second touchdown drives, their defense making a stand and Harrison Butker kicking game-winning field goals.

All of Butker's field-goal attempts Sunday came from under 40 yards, with his longest being a 36-yard field goal in the second quarter. He connected on a 28-yard field goal in the third quarter and hit the eventual game winner from 20 yards out late in the fourth quarter.

Nix, the Broncos’ ever-improving rookie quarterback, threw two touchdown passes to give visiting Denver a 14-10, first-half lead on the favored Kansas City Chiefs on a brilliantly bright early November Sunday afternoon at GEHA Field at Arrowhead Stadium.
