Harry Trotter took over the young UCLA football program after Cozens stepped down after guiding the Bruins in their first season. UCLA began to play in the Southern California Intercollegiate Athletic Conference (SCIAC) in 1920, and competed against Occidental College, California Institute of Technology, University of Redlands, Whittier College, and Pomona College. Coach Trotter's two wins were against Redlands and San Diego State, which did not join the SCIAC until 1926. Trotter left UCLA with a 2–13–1 record in three seasons (1920–1922). James J. Cline took over the Bruins football program as its third head coach in 1923. Coach Cline's two wins were against Loyola University and San Diego State. Cline was replaced after two seasons and a 2–10–3 record.
