A busy man On the Texans’ only touchdown drive in what turned out to be a 16-10 victory at Arrowhead Stadium, backup running back Chris Brown had carries of 12, 6, 3 and 2 yards — the latter a touchdown. “It was nice to hit somebody different for a change,” Brown said after averaging 4.2 yards a carry. “I’ve been working really hard, and it looks like it’s starting to pay off. I hope we can build on this.” Steve Slaton, the second-year running back who is firmly entrenched as the starter, gained only 7 yards on four carries before departing for the night. Brown finished with 25 yards on six carries. He had two catches for 22 yards. Brown, 6-3, 234, is larger than Slaton, 5-9, 215. “We want to run the ball better in the red zone, and we were able to do that tonight,” Schaub said. “It was huge to have Chris come in and do what he did. He’s a nice change of pace. When he gets the ball, he doesn’t let the first guy tackle him.” Brown played in the Texans’ running game at the University of Colorado. When Texans assistant head coach/offense Alex Gibbs was Denver’s offensive line coach, he helped the Buffaloes coaches install the system. “It was exciting,” coach Gary Kubiak said about Brown’s contribution. “He’s a big back who loves to run in the red zone.” Ryan Moats replaced Brown and carried 10 times for 52 yards, with a long gain of 14. Like the backs who played before him, Moats was the beneficiary of some stout blocking from his linemen.
