In a game where both offenses struggled from the onset, KC's defense outplayed the Bears' D just enough for the red and gold to pick up this win.
Here are the report card grades for every Chiefs unit in this win against the Bears.
QB Tyler Palko and the Chiefs' offense had another rough game on Sunday.
They racked up only 252 total yards in the game and failed to reach Bears' territory until very late in the fist half.
Although they were able to score 10 points, their only touchdown came on a fluke Hail Mary pass that was tipped into the hands of RB/WR Dexter McCluster right before halftime.
However, even though he only threw for 157 yards in the game, Palko was able to keep his offense and team in the game by not turning the ball over at all in this contest.
Overall Grade: D
The Chiefs' defense had easily their best game of the 2011 season on Sunday against Chicago.
Led by rookie OLB Justin Houston, they sacked Caleb Haine seven different times, which rattled the young starting QB.
They also held the Bears under 200 total yards for the game, which was the lowest number of yards that KC has given up this year.
On top of all that, they were also able to force three turnovers by picking off Haine three different times, with one of those interceptions occurring in the red zone.
Overall Grade: A
Like the defense, Kansas City's special teams unit also enjoyed a very good day against the Bears on Sunday.
Kicker Ryan Succop made yet another field goal in his only attempt, while punter Dustin Colquitt did an excellent job of virtually taking Pro Bowl KR/PR Devin Hester out of the game.
Hester was only able to return three of Colquitt's 11 punts on the day, and his 44-yard return in the second half didn't end up hurting the Chiefs in the end.
I would have given this group an A if the Chiefs' return game would have played a little better in this game.
Overall Grade: A-
The Chiefs' coaching staff had an up and down day against the Bears in Week 13.
First of all, defensive coordinator Romeo Crennel designed an excellent game plan on defense for the Chiefs, as they had the Chicago offense out of rhythm all game long.
However, Bill Muir and the offense was a much different story.
KC managed to only pick up 12 first downs in the game, and were so predictable that the Bears defense seemed to know exactly what they were going to do by the fourth quarter.
Overall Grade: B-
