The Kansas City Chiefs got the only grade that really matters against the Denver Broncos on Sunday: W. It's hard to grade a game like this because you see plenty of area where they can improve or places where they made mistakes. But at the end of the day it was all enough to win.

Here's my break down of the Chiefs grade for the Broncos game:

Offense: B-

The Chiefs did some good things on offense but made their share of mistakes. They nearly hit 200 yards rushing...but also fumbled it once. They drove inside the Broncos five yard line two times...but only scored on one of those. Dexter McCluster had a huge run on an end-around...but it was called back.

KC had no second half points but did enough to win. I think most everyone knows they won't win many games scoring 10 points.

Defense: B+

Kyle Orton did not look the Kyle Orton we've seen this season. He completed just 9-of-28 passes for 117 yards and the Chiefs consistently pressured him, which didn't happen the first time around. KC's secondary is really what pushed this game to their favor but the rush defense kept Denver in it. Knowshon Moreno racked up 161 yards on the ground. His top two career games? Both came this year against the Chiefs. KC should have known that was coming. Luckily Denver abandoned the run and Moreno's attack didn't hurt the Chiefs on the scoreboard.

I imagine there's a stat out there on teams who have 161-yard rushers and that win more than they lose. KC's defense did a solid job of keeping points off the board despite the rushing yards.

Special teams: B

It was Dexter McCluster's return but KC didn't do anything too exciting on either side. Interesting to see Todd Haley punt it rather than attempt a 50-yard field goal.
