As Alcorn State's athletic director, Casem also oversaw 13 regular season men's basketball titles and three regular season women's basketball championships. In 1979, Alcorn State's men's basketball team became the first historically black university to capture a win in the National Invitational Tournament. He also led the effort to build the Davey L.

He has also been inducted into the SWAC Hall of Fame, Alcorn State Hall of Honor, and Mississippi Sports Hall of Fame, and has received the National Football Foundation Outstanding Contribution to Amateur Football Award and the Football Writers Association Citation of Honor. Casem is credited with saying, "On the East Coast, football is a cultural experience. In the Midwest, it's a form of cannibalism. On the West Coast, it's a tourist attraction. And in the South, football is a religion, and Saturday is the holy day." In 1999, he also received the 28th NACDA/NIT Athletics Directors Award for his contribution to the sport of basketball and the National Invitational Tournament. On receiving the award, Casem said, "That you have seen fit to recognize me with this most hallowed award is, in essence, not just a tribute to me, but a tribute to all of the historically black colleges and universities, the many talented student-athletes, the outstanding coaches, motivated staff members, distinguished administrators and supportive fans who stood in our corner." Casem died April 25, 2020.
