Bearg was the 15th and then again the 20th head football coach for the Washburn Ichabods. He first held the position for two seasons in 1918 and 1919 and again for seven more seasons from 1929 until 1935. Bearg's overall record at Washburn was 46 wins, 33 losses and 4 ties.
After coaching for four seasons at Nebraska, Bearg led the Ichabods to a 35–31 record and the 1931 Central Conference championship. Two of his team's three losses during the 1931 season came to the Kansas and Kansas State.
Under Bearg's leadership, Nebraska won its first Big Six Conference title in 1928 when his team went 7–1–1. The Cornhuskers were conference runners-up in 1926 and 1927. According to Nebraska's official athletics website, Bearg fielded powerful team during his four years at the helm but "fans criticized him for not using strategy and deception, which eventually led to his resignation." After four seasons in Lincoln, Bearg was replaced by future College Football Hall of Fame coach, Dana X. Bible.
