From the talent in the 2015 draft class, Todd McShay sees the Pittsburgh Steelers' intent on adding to the focus of players on the defensive front, namely defensive tackle Malcolm Brown from the University of Texas.
Brown is a huge senior standing at 6-foot-3 and 317 pounds heavy. His specialty was being able to be a hybrid defensive lineman for the Texas Longhorns as they employed him at nose tackle, defensive tackle, and defensive end in both 3-4, and 4-3 fronts used in the NCAA 2014 season.
McShay sees the Steelers making a point to grab Brown because of his ability to be diverse on the defensive line. It would make sense to have a player that could either become more of a force at the nose tackle position, or at least be a depth player for any spot on the defensive line. Injuries have limited the depth of available defensive linemen for the Pittsburgh Steelers in 2014, so it is reasonable to expect them to address this area of their roster early in the draft.
