Hyman served as athletic director of Texas Christian University from 1997 to 2005. During this period he was named the 2004 national athletic director of the year.
Hyman came to South Carolina in 2005. He was named the 2003–04 Street and Smith's Business Journal National Athletics Director of the Year and was also selected as the Division I-A West Regional Athletics Director of the Year by the National Association of Collegiate Directors of Athletics (NACDA). In September 2008, he assumed the duties as President of the Division 1A Athletic Directors' Association.
While generally athletic directors are evaluated using a variety of success metrics relating to athletic and academic performance of student athletes, Hyman views his role as one of "managing expectations", encouraging decisionmakers to accept a lower level of success.
