HOUSTON -- Houston Texans head coach Bill O'Brien said he thought quarterback Brock Osweiler had a good debut for Houston on Sunday, especially considering it was his first outing.

Osweiler was a little harder on himself.

After the Texans' 23-14 Week 1 victory, Osweiler said one area he knew the offense could really improve on was their production in the red zone.

"It's so hard to get the football down in there, so when you do you really need to capitalize on your opportunity," Osweiler said on Sunday.

Osweiler finished 22-for-35 for 231 yards with two touchdowns and an interception.

The Texans were 1-for-3 in the red zone against the Bears, the only touchdown coming on a pass in the fourth quarter to rookie wide receiver Will Fuller. That score put the Texans ahead for good.

"We need to do a better job there, no doubt about it," O'Brien said. "I think Chicago might have been 2-for-2 down there. We were not as good down there. Kansas City is a good red-zone team.

"We are definitely going to focus on trying to improve in the red area."

The Chiefs were 4-for-5 in the red zone on Sunday during their 33-27 overtime win over the San Diego Chargers.

The Texans start focusing on their play in the red zone on Thursday and Friday, and Osweiler said after watching film of Sunday's game that he still sees a lot of improvement that can happen in that area.

"We need to improve as an offensive unit in the red area," Osweiler said. "Any time you get down in the red area you need touchdowns. Field goals are obviously great. Any time you can get points it's good. Points are hard to come by in the National Football League. But if you're consistently kicking field goals rather than scoring touchdowns, there's going to come a point where that comes back to bite you.

"After watching the tape, reviewing the tape, I just feel like there were some missed opportunities, whether that was me making a wrong read or maybe we had a guy in the wrong spot, whatever it was, we just weren't on the same page, we weren't executing. I think we can be a lot better, and we will be a lot better."
