Texans prepare for talented rookie Luck

Two weeks later, they get a shot at Andrew Luck, the No. 1 overall pick in the NFL draft last April, and they can clinch the AFC South title with a win.

Luck has thrown for 3,792 yards for the Colts, but leads the AFC in interceptions with 18, and has lost five fumbles. He's also been sacked 32 times, and will now have to deal with AFC sacks leader J.J. Watt.

"We need more sacks," said Watt, who has a single-season franchise record with 16½. "I need to rush the passer better. As a defensive line, we need more pressure and we need to bat some more balls. We'll put it on us up front."

Coach Gary Kubiak noted that Luck is challenging because even if the defense gets to him for a sack, his size (6-foot 4, 234 pounds) makes him difficult to bring down.

"It's got to be a big conscious effort for us to keep him contained, and then when we do have our opportunities you got to really work to bring him down," Kubiak said. "You can make just an incredible highlight reel of people just hanging on to him and him still making plays."

Kubiak likened Luck to Ben Roethlisberger because of his size, and said that when he was studying the draft last year he thought he was the best quarterback to come out since his predecessor Peyton Manning.

"He's sure as heck hasn't disappointed," Kubiak said. "He's been excellent this year. I told the team he's playing like an eight-, nine-year football player. He's handling a ton of offense."

Despite his development, Luck hasn't found a way to limit his turnovers. He's had three games this season with three interceptions, and two of them have come in the last four games. He has nine interceptions in the last four games.
