Vegas odds: Chiefs are a one-score favorite vs. Broncos

Peyton Manning hasn't lost in Arrowhead Stadium since he left the Colts.

Oddsmakers know that -- but they're still picking the Chiefs to beat the Broncos on Thursday night.

Head coach Andy Reid's team is a three-point home favorite in primetime. That means the game would be a pick 'em if it were held in Denver.

Manning's recent struggles make his team the underdog. He hasn't quite grasped the entire new playbook and hasn't seemed like his usual, touchdown-tossing self.

Meanwhile, the Chiefs new-look offense marched into Houston and took it to a playoff-level defense.
