Texans defensive coordinator won't change the basic role of defensive end Mario Williams. "I think Mario fits in well with what we're going to do," Phillips said. "He's a five-technique, an outside rush guy. That's what he is. I don't see any difference for him. He's going to be outside all the time." Williams, who will be in the last year of his contract, will be asked to constantly pressure quarterbacks. Phillips has no plans for Williams to stand up. While watching film of Williams and seeing the few times he did rush from a standing position, Phillips noticed he took a false step when the ball was snapped. "When they did stand him up, he took that false step every time, and that made him late on his rush," Phillips said. "You don't want him late on the rush. That's just fundamentals, something you have to work on. That's what happens when you have a player who's not used to standing up stand up. "I don't think you need to stand Mario up. He comes off the ball so well with his hand on the ground I don't know that you'd ever want to stand him up."
