Rapid Reaction: Texans 17, Steelers 10

HOUSTON -- Thoughts on the Texans’ 17-10 win against the Steelers at Reliant Stadium.

What it means: The Texans move to 3-1 and maintain a share of first place in the AFC South. We saw some of the second-half killer instinct that’s been a question, which is a very good sign.

What to worry about: Receiver Andre Johnson left the game in the second quarter with a hamstring injury and didn’t return. Matt Schaub did well finding tight end Owen Daniels in his absence. But any extended absence for Johnson will be a significant dent to the Texans’ high-powered offense.

What I liked: On a crucial late possession by the Steelers, Antonio Smith and Mario Williams collected back-to-back sacks of Ben Roethlisberger, forcing a punt from deep in Steelers’ territory. Also, Arian Foster played his first full game of the season after dealing with a hamstring injury and ran hard, with 30 carries for 155 yards and a touchdown. That meant 138 passing yards were enough.

What I didn’t like: Penalties hurt the Texans, though they overcame several. They should have been up 17-0 instead of 10-0 at the half, but a blocked field goal attempt by Danieal Manning returned for a touchdown by Johnathan Joseph was wiped away by an illegal block above the waist by Manning. It was completely unnecessary and could have been an absolute killer.

What’s next: The Oakland Raiders come to Houston and the Texans will need to stop Darren McFadden, who’s been one of the league’s top running backs so far.
