The Denver Broncos (13-3) defeated the Kansas City Chiefs (6-10) on Christmas night at GEHA Field at Arrowhead Stadium. Here are grades on the Broncos’ performance from Thursday’s 20-13 win: Offense It’s not about style points with the Broncos offense. Denver only scored 20 points and won by seven despite having the ball for over 39 minutes. Denver had three drives of 14 plays and one of 16. Bo Nix ran and passed for a touchdown in the win. Rookie RJ Harvey scored the winning touchdown and rushed for 43 yards. Denver’s offense got the job done. Grade: B Defense This unit did what they were expected to do against Chiefs third-string quarterback Chris Oladokun. The only time Kansas City was able to score was when it had short fields.

In the end, Denver still had to make the important stop with the game on the line. Grade: A Special teams Kicker Wil Lutz hit two field goals and two extra points in the win.
