Reunited now with the Texans, Clowney's speed still catches Swearinger off guard sometimes.
"You watch him on film and you'll be like 'Woo! Where did that come from?'" Swearinger said. "There will be some plays were he'll be a blur and you're like, 'Where did that come from?' That is something that he used to do all of the time at South Carolina and we're just ready for him to do it here and help this defense."
Last season, the Texans' defense ranked 29th in sacks. Defensive end J.J. Watt had 10.5, but the outside linebackers combined for 10, with Whitney Mercilus notching seven. It's unusual for a 3-4 defensive front to get most of its pressure on the quarterback from its defensive line, but that was the case in Houston. Clowney will be tasked with helping outside.
And even while he continues on the path to being fully cleared, outside linebacker Clowney has impressed teammates on both sides of the ball.
"Heck of an athlete, he's very hungry to learn and be a good player and I really like to see that," left tackle Duane Brown said. "He comes in here, he works his tail off. He's new, he's fresh and it's still early, but I think he's going to be as good as he wants to be."
