Mercilus learning finer points of 3-4

Rookie DE/OLB Whitney Mercilus on the biggest adjustment from the 4-3 at Illinois to the Texans' 3-4 scheme: "Having my hand down a lot and just being up in a two-point (stance) and getting that good get-off. A three-point is kind of like a track stance, you're able to get off faster. I'm always trying to adjust that."
