[2] In the 2005–06 season, Edgar was on Bruce Pearl's staff on a Tennessee team that won the Southeast Conference East Division title.
[3] On April 13, 2006, Edgar was named head coach at Southeast Missouri State.
[3] This position brought him back to the Ohio Valley Conference (OVC), where he started with Murray State.
On October 9, 2008, Southeast Missouri State fired athletic director Don Kaverman and suspended Edgar after the NCAA notified the university of possible major violations, three months after both the men's and women's basketball programs were placed on two years' probation by the NCAA.
[6][7] The NCAA investigation concluded in August 2009 and found that impermissible tuition payments and violations of rules about summer conditioning activities and observing pickup games happened under Edgar's watch; Edgar's appeal was rejected in June 2010.
