Kansas City's loss has to sting, but it's a stage of development that Todd Haley's young club must endure: Learning how to close the deal on a road upset when the home team is ripe for the taking. But from a big-picture standpoint, the Chiefs being 3-2 and still in first place in the AFC West is still progress any way you cut it. You can have the rest of the field, I'll take Thomas Jones and Jamaal Charles as the NFL's best two-back combination this season. The Chiefs tandem produced 193 yards rushing at Houston, with Jones gaining an even 100 yards and a touchdown on 19 carries, and Charles adding 93 yards on 16 attempts. Overall, Kansas City gouged the Texans for the aforementioned 228 yards rushing, gaining an average of six yards a pop on 38 carries. Jones (338 yards) and Charles (418) have already combined for 756 yards rushing through five games, and they're not wearing down -- they're getting better.
