I don't know if it has been posted but i came across this on ESPN.com With J.J. Watt and Brooks Reed joining Mario Williams and Antonio Smith, the Houston Texans suddenly find themselves with an abundance of defensive end/linebacker types, but still have no true nose tackle. Although new defensive coordinator Wade Phillips is best known for running a 3-4 defense, will the Texans' personnel lend itself to more of a 4-3 style? Phillips himself says he'd be comfortable with such a move. He tells Albert Breer of the NFL Network that he used the 3-4 when he was with the Buffalo Bills, until the team suffered a rash of linebacker injuries. "And so we played a 4-3 against Miami, and beat them, and then we went back to the 3-4 when we got healthy," Phillips said. "It's the players you have and how you play. It's not 3-4 or 4-3." Breer says the key question for the defense is this: How best to use Mario Williams? "My guess is that the first priority for Phillips is figuring how to deploy Williams down-to-down and building around that plan, much like he did with DeMarcus Ware in Dallas," Breer writes. "Could that lead to playing some 4-3 alignments? Perhaps."
