After Compton J.C., Rozelle attended the University of San Francisco, where he became USF's publicity director for athletics. He graduated in 1950 and took on a 2nd job, assistant athletic director. Two years later, he was hired by Schramm to be the Rams' PR director. In 1955, he left to become a partner in a firm that did publicity work for the 1956 Olympic Games in Melbourne, Australia. He returned to the Rams as general manager in 1957.
On January 26, 1960, Rozelle was voted NFL commissioner after seven days of balloting. He was told of his election in the bathroom, and when he emerged, he jokingly told owners, "I come to you with clean hands." Rozelle was chosen as a compromise after owners could not agree on 2 other candidates.
