Rapid Reaction: Kansas City Chiefs

DENVER -- A few thoughts on the Kansas City Chiefs' 27-17 loss to the Denver Broncos on Sunday:

What it means: The 9-1 Chiefs lost for the first time this season but more importantly they relinquished sole possession of first place in the AFC West. They are now tied with the Broncos for first place in the division. After stepping away to face different opponents next week, the teams will face one another again on Dec. 1, this time in Kansas City.

Stock Watch: Rookie cornerback Marcus Cooper had his worst game of the season. He was beaten by Demaryius Thomas for a 70-yard gain. The Chiefs’ pass rush had its third straight sub-par game. Kansas City couldn’t get much pressure on Denver quarterback Peyton Manning, even when Manning was holding on to the ball for longer periods. The red zone offense was again ineffective. The Chiefs scored two touchdowns in their four trips inside the Denver 20. But they came away with no points on one such trip when fullback Anthony Sherman lost a fumble. Wide receiver Dwayne Bowe, one week after being arrested for possession of marijuana, had one of his better games of the season. Bowe caught four passes for 57 yards and Kansas City’s only touchdown.

Double-digit deficit: The Chiefs fell behind by 10 points at two different junctures in the first half. That’s the first time this season they have trailed by more than a touchdown. Predictably, things didn’t go well after that for the Chiefs, who were never able to catch up. Entering the game the Chiefs had not scored a touchdown on offense in six quarters. They managed two touchdowns against the Broncos, one coming with less than five minutes remaining in the game.

What’s next: The Chiefs have another game against a divisional opponent on Sunday when they play against the 4-6 San Diego Chargers at Arrowhead Stadium.
