 His father was a second baseman in the Pacific Coast League.
 While attending USC, the younger Mohler was the student council president, played baseball and played at the quarterback position for the USC Trojans football team.
 He led the 1931 USC Trojans football team to a national championship and a victory in the 1932 Rose Bowl, and, at the end of the 1931 season, he was selected by the Central Press Association as a second-team All-American fullback and by the Associated Press as a third-team All-American quarterback.
 In 1933, after graduating from USC, Mohler played professional baseball in the Pacific Coast League for the Mission Reds.
 He was married in 1933 to Bernadine Olson.
 He died in the crash of an Air Force plane in 1949 and was posthumously inducted into the USC Hall of Fame in 1995.

 USC concluded their season with two thousand-yard receivers (Robert Woods and Marqise Lee), a thousand-yard rusher (Curtis McNeal), and a 3,000-yard passer (Matt Barkley) for the first time since the 2005 season, when Kiffin served as offensive coordinator.
