Administrative career
University of Illinois Chancellor Richard Herman was quoted in July, 2006 as saying: "If he's not the best AD in the country, I want to know who is." and "He does a wonderful job of bringing in great coaches and building a team that understands what athletics is and needs to be about."[2] (Herman was later relieved of his duties after a scholarship scandal.)
