One thing the Texans do is run the ball whether it is working or not.
Several weeks ago, the Texan run game was abysmal averaging 87 yards/gm (28th) and 3.3 yds. per carry (last). Since then and probably due to somewhat poorer competition, they have improved to 108 yards/gm (15th) and got out of the cellar with 3.7 yds. per carry (tied for 28th).
The Chiefs are a step up in run defense - they give up 98 yards/gm rushing (8th) and allow 4.1 yds. per carry (tied for 16th with the Texans and Raiders). If the Texan run game is truly improving, then Saturday will be a good test....

Statistically, the Chiefs defense and the Texan defense are just about one and the same. I might give the edge to the Texan defense going into the game because they got their best stats in the 2nd half of the season - i.e., on a bit of a roll.....
--------------------------------------------------------
One edge going the Chiefs way is there giveaway/takeaway of +14, 2nd in the NFL behind only Carolina's +20. The Texans managed to get into positive territory finishing the season at +5 after being -8 at one point in the year.

Alex Smith is your ultimate don't-turn-the-ball-over/conservative passing QB (not many giveaways) while the Chiefs defense is pretty good at the takeaways....

Speaking of rolls, the Chiefs have won 10 in a row. That's "hot" in today's NFL. Obviously, a big test for the Texans this Sunday...............
