DePaul men's basketball coach Oliver Purnell has resigned after five seasons. The school announced that the former Maryland assistant is stepping aside after leading the Blue Demons to a 54-105 record. DePaul hired Purnell, who was born in Berlin in Worcester County and attended Stephen Decatur, hoping he could revitalize a once-proud program, but the Blue Demons lost at least 20 games in four of his five years, including a 12-20 mark this season. They have not reached the postseason since the 2006-07 team made the National Invitation Tournament and their most recent NCAA appearance was in 2004. Purnell is 448-384 in 27 seasons at Radford, Old Dominion, Dayton, Clemson and DePaul. He was a Terps assistant from 1985 to 1988.
