During World War II, Morgan served in the U.S. Navy and was the commander of a torpedo boat in the Pacific Theatre of Operations.

Morgan's championship teams at UCLA included individual champions, including Edith Sigourney, Arthur Ashe, and Charles Pasarell, and outstanding players such as Mike Franks, Mike Green, Allen Fox, and Larry Nagler.

"[2] During his tenure as athletic director, UCLA won 30 NCAA championships—ten in basketball, seven in volleyball, six in tennis, four in track and field, and three in water polo.

[1] Morgan also oversaw the completion of Pauley Pavilion and the construction of Drake Stadium, Spaulding Field and a boathouse for crew in Marina del Rey.

Morgan's outbursts reportedly resulted in a rule change banning athletic directors from sitting on the bench during basketball games (during the 1973 National Invitation Tournament, Alabama athletic director Bear Bryant, also the school's legendary football coach, violated this rule, but the officials did not penalize the Crimson Tide).
