Coiner will fill the opening on the staff created by the resignation of defensive line coach John Blake.
"One of the real added pluses is that he brings a level of expertise with special teams," Davis said of Coiner. "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 been an assistant special teams coordinator in the National Football League. He's a good football coach. He's smart, he's bright, he's got good communication skills, he's a good teacher [and] he's got a unique perspective in that he has seen an awful lot of very good football players and how they play. I think it's a good addition. He's got a close personal relationship with several of the coaches on our staff and I think that from a chemistry standpoint, that was critically important – if you're going to add someone at this stage into the mix, it needs to be somebody that's got really good chemistry and enthusiasm. I think that certainly Charlie will bring that."
Coiner, who was released from his coaching position with the Buffalo Bills in January, has ties to three of UNC's current assistant coaches.
The Waynesboro, Va. native earned his bachelor's degree from Catawba College and his master's from Appalachian St., where he began his coaching career as a graduate assistant ('83-'86), the same time UNC defensive coordinator Everett Withers was a standout player for the Mountaineers and UNC defensive backs coach Troy Douglas was a starting wide receiver there.
Coiner worked with the Chicago Bears on offense and special teams from '01-'05, before taking the tight ends job with the Bills in '06. Coiner joined the Bears' staff as the offensive quality control coach during current UNC offensive coordinator John Shoop's tenure as Chicago's OC ('01-'03).
