Senior Brandon Dunn is the swing man on the defensive line, playing either defensive tackle or nose. The massive tackle recorded 28 tackles and two sacks last season and is a big run-stopper in the middle of the defense.
Redshirt freshman Pedro Sibiea is another big body on the defensive line who will add depth to the defensive front. He had a solid spring and is a good addition to the line this season.
Senior Roy Philon has battled back injuries, which kept him out of spring practice. The Lexington, Ky., native registered 27 tackles and 2.5 sacks last year after playing through intense pain. If healthy, Philon can be a major force at tackle.
Junior B.J. Dubose is back after missing half of last year. A 6-foot-5, 273-pounder, Dubose registered 15 tackles in limited action, but proved to be a disruptive force. By adding additional weight, Dubose will likely move inside.
At the nose position, junior Jamaine Brooks came on last season and was an impact player for the Cardinals. Another big body at nose tackle, Brooks totaled 19 stops and could be headed for his best season in 2013. He suffered a leg injury that should keep him out for the first few weeks of the season.
Sophomore DeAngelo Brown received playing time last season as a true freshman and gives the Cardinals another big, athletic body at tackle. Incoming freshmen De’Asian Richardson and Kyle Shortridge also will be key contributors to the defensive line this season.
