Not a coaches issue, it was a compliance issue. Student-athletes can intern anyplace they want, provided that they fulfill the same duties that other interns at the place of employment do and have done in the past. Like any other job, the employer cannot use the student athlete and the fact that they are working there to promote the business.
In this case, both of these were potential violations. Previous and current interns at the station had not been given jobs as regular co-hosts of a show. They had done production, learned the board, and made occasional on-air appearances.
Second, the station HEAVILY promoted the student-athlete and his appearances on the show. That cannot happen. It would put his eligibility at risk and violate the SEC policy on live student-athlete interviews.
That SEC policy only allows student-athletes to be interviewed live on air by the school's radio/TV network as a part of game broadcasts and specialty shows (VolCalls, etc.) and as a part of official SEC events like tournaments and media days.
Other athletes have done local media internships in the past at various outlets. At one point last year, there were athletes working with all three TV stations and two radio groups. It's allowed. But the way that station elected to do it, even after receiving documentation from UT on what could and could not be done, made it impossible.
