Spring Wrap-up: Defense Posted Apr 16, 2010 One of the primary goals for the defense this spring was to give some of the guys on the two- and three-deep some repetitions. What did you see this spring from those guys that should be encouraging for UNC? Don Callahan: Mywan Jackson was very encouraging and not just because of the interceptions he had. During the spring game he looked instinctive defending both the pass and the run. He also flashed his tackling ability. (Inside Carolina)
