Defensive end J.J. Watt is considered the best defensive player in the NFL. A lot of Texans fans are wondering how he will fit into new defensive coordinator Romeo Crennel’s 3-4 scheme that’s different from the 3-4 used under Wade Phillips.

Watt’s strength is getting off the ball, getting up the field and creating chaos in the backfield, whether it’s chasing the quarterback or harassing the running back.

Phillips’ 3-4 was closer to a 4-3 than a traditional 3-4 that Crennel has played. In Crennel’s system, defensive linemen are responsible for two gaps on run downs – grab, hold, read and shed. That’s not Watt’s strength.
