Given the opponent and the environment Sunday, the Broncos offense and rookie quarterback Bo Nix did a lot of good things. Kansas City boasts one of the NFL’s most formidable defenses and veteran coordinator Steve Spagnuolo can tie quarterbacks of any experience level in a knot. Arrowhead Stadium might have been hosting a day game for the first time this season, but it was loud under the afternoon sunshine. Payton called Nix’s performance “gutsy” after the game and it was that. The rookie completed 22 of 30 passes for 215 yards and a pair of first-half touchdowns.
