Wrap-up: Chiefs 19, Packers 14

A look at the Kansas City Chiefs' stunning 19-14 upset of the Green Bay Packers.

What it means: The Chiefs have derailed history. This game will be talked about in future years when teams go undefeated well into December. This has to be one of the Chiefs’ regular-season highlights in recent memory. In their first game after firing coach Todd Haley, the now 6-8 Chiefs knocked off the 13-1 Packers and did it in fairly convincing matter.

Crennel’s candidacy: Interim coach Romeo Crennel couldn’t have helped his cause any better than he did Sunday. He was already a candidate to be the permanent coach and after leading the team to this win, he’ll take a major step closer to becoming the head man in 2012.

Orton provides spark: What a way for Kyle Orton to make his starting debut for the Chiefs. He was 23-of-31 for 299 yards passing. It was a highlight of a difficult year for the former Denver starter. If Orton finishes strong in the next two games, Kansas City could potentially consider signing him and replacing Matt Cassel.

Stalling in the red zone: The Chiefs could have won this game by 20 points, but they kept stalling in the red zone. In the end, it didn’t hurt the Chiefs.

Great defensive effort: The Kansas City defense has been up and down this season. It gave up 37 points last week to the Jets, but did a great job Sunday against the best offense in the NFL. Great work by Crennel’s defense.

Finally AFC West trouble: In each of its three previous games against the AFC West this season, Green Bay scored at least 45 points.

What’s next: The Chiefs host Oakland on Saturday as they look for the season sweep over their division rival.
