UNC Spring Football: Leaders emerging on defense Posted Mar 10, 2016 Cayson Collins, Cole Holcolmb and Dan Mastromatteo were seen taking first-team reps at linebacker on Tuesday. One interesting scenario is what junior college transfer J.B. Copeland can do. He will be eligible to play in the Fall and has two years of college football under his belt. Larry Fedora is unsure of his potential at this point in Spring practice. (Carolina Blue)
