Jones has said multiple times that depth on the defensive line this spring is a question to the point where it could be difficult to have full practice drills at that spot.
Out: DE Derek Barnett, LB Darrin Kirkland Jr., DT Danny OBrien, DE Kyle Phillips, WR Jason Croom, Curt Maggitt
Questionable/limited: WR Marquez North, DT Trevarris Saulsberry, TE Alex Ellis, RB Jalen Hurd, DT Owen Williams, OL Chance Hall, DL/OL Charles Mosley, LB Dillon Bates, LB Jakob Johnson, DE Corey Vereen, DB Rashaan Gaulden.
The defensive line has been especially hit hard with Barnett, OBrien, Phillips, Saulsberry, Williams, Mosley and Vereen all dealing with some form of injury. Newcomers Shy Tuttle and Andrew Butcher, along with rising sophomores Kendal Vickers and Dimarya Mixon and rising junior LaTroy Lewis are the only scholarship defensive linemen who havent been mentioned as having injury concerns heading into the spring.
