North Carolina’s running game is going to get a makeover this offseason. As coach Larry Fedora enters his second season, he does so arguably with a bigger challenge on offense than he did at this point a year ago. With Giovani Bernard, the nation’s top punt returner and No. 11 rusher, leaving two years early to enter the NFL draft, the Tar Heels will lose their most explosive playmaker on both offense and special teams. Equally as important, though -- if not more -- is the fact that All-American offensive tackle Jonathan Cooper, who was Bernard’s lead blocker, is also gone along with two other starters on the offensive line.
