North Carolina hires Charlie Coiner
Coiner takes over for John Blake, who resigned amid an NCAA investigation into improper contact with agents.
"He's got a diverse background," Davis said of Coiner, who was fired by the Bills in January. "He started his career early on the defensive side of the football. He's going to work with our defensive ends and our defensive tackles. We're still in the transition area of that."
Davis said defensive coordinator Everett Withers and linebackers coach Art Kaufman will continue to help coach the defensive line until Coiner has gained enough exposure to the program and its personnel.
Prior to joining the Bills, Coiner coached the special teams for the Chicago Bears from 2001 to 2005.
"One of the real added plusses is that he brings a level of expertise with some special teams," Davis said. "It's unrealistic to expect in a short two- or three-day period of time that we'll see the effects of what he'll be able to do, but he's a good football coach. He's smart, he's bright, he's got good communication skills. He's a good teacher. He's got a unique perspective in that he has seen an awful lot of very good football players and I think it's a good addition."
Davis said Coiner had a strong pre-existing relationship with several of the coaches on staff, which was important, considering the timing of the hire.
North Carolina hosts Georgia Tech on Saturday in the ACC opener for both teams.
