UNC's third Notice of Allegations from the NCAA is notably harsher than its immediate predecessor.
References to football and men's basketball in the first NOA disappeared in the second, but both sports are back in the third NOA, which UNC released on Thursday.
"Many at-risk student-athletes, particularly in the sports of football and men's basketball, used (anomalous AFAM courses) for purposes of ensuring their continuing NCAA academic eligibility," the new NOA said.
Director of Athletics Bubba Cunningham said he was surprised and disappointed by the entire third NOA.
"I have never seen three notices on the same case," he said.
UNC's response, which is signed by Kansas lawyer Richard Evrard, said the University has not been treated fairly and consistently.
"The University wants to move this matter forward, but now faces a third Notice of Allegations in a process that increasingly lacks clarity on what the University is expected to defend," the letter said.
Cunningham reiterated that point in a conference call after documents were released. He said UNC is concerned that NCAA staff members and the Committee on Infractions have inconsistently applied bylaws during the investigation.
"We believe that the process has gotten off track, and we have serious concerns about that," he said.
