Jadeveon Clowney calm entering opener

HOUSTON -- In his limited preseason playing time, Houston Texans outside linebacker Jadeveon Clowney made a few eye-popping plays.

Three, if you ask defensive coordinator Romeo Crennel.

"There was about three plays that I saw that I really liked, you know, during the preseason," Crennel said. "If he can continue to do that, I’m going to like him a lot more."

Clowney missed a little more than a week and a half, missing the Texans' final two preseason games while recovering from a concussion. He says he's fine now, and the preparation has helped calm him. Before his first preseason game, he had some nerves. Now?

"Knowing what to do, knowing who I'm going against, who I'm facing [helps]," he said. "So I'm not really nervous, just ready to get into it."

Washington is an opponent that could provide some opportunity for Clowney and the rest of the Texans' pass rushers. According to ESPN Stats & Information, via our Washington writer John Keim, quarterback Robert Griffin III was under duress on 101 dropbacks in 2013 and completed 47.5 percent of those passes for a 62.4 passer rating. Griffin still presents a special challenge, however.

"One of the best running quarterbacks in the league, I think," Clowney said. "You’ve got to be ready to contain him in the pocket because he can get out there [and] can cause havoc because he can run pretty fast. ... It's going to be a challenge because you can't rush how you want to; you can't take a lot of inside moves because you know he can pop out for a first down and yards."
