A group of North Carolina football supporters who agreed to help fund Kenan Stadium’s “Blue Zone” project wants more information about why head coach Butch Davis was fired – and may explore legal action depending on the answers they receive. Don Brown, one of five attorneys representing the group, had his firm fax a public records request to UNC Monday asking for all correspondence – including emails, text messages, letters and voice recordings – between the Chancellor Holden Thorp and various University officials. The issue, according to Brown: Why was Davis terminated just nine days before fall practice, after repeated statements over the past year supporting him as UNC’s head football coach? “I can tell you, everybody that we represent is furious about the timing of Butch Davis’ firing,’’ Brown, whose Brown & Associates firm is based in Charlotte, said during a phone interview this morning. “They feel like their investment was based on Butch Davis being the head coach … and the public reassurances over the past year that he would remain the coach. … They want answers.”
