UNC Hires Charlie Coiner to Coach Defensive Line Posted Sep 15, 2010 Charlie Coiner will join the UNC football staff, Butch Davis announced Wednesday. “He’s got a diverse background,” Davis told reporters during Wednesday’s ACC teleconference. “He started his career on the defensive side of the football...and he’s going to work with our defensive ends and defensive tackles." Coiner will fill the opening created by the resignation of defensive line coach John Blake. (Inside Carolina)
