In 1910, Glaze became the football coach at Baylor University. His teams had a record of 12–10–3 from 1910 through 1912, including a 6–1-1 mark in his first year. Glaze became the head coach of the University of Southern California's football team for the 1914 and 1915 seasons, compiling a 7–7 record. He was the first coach after USC's teams began to be known as the Trojans. Before his arrival, USC had not played football for the previous three seasons; like many universities at the time, the school had switched to rugby and did not field football teams during the 1911 through 1913 seasons. After competing primarily against southern California teams throughout its history, USC was now beginning to include major colleges from other areas on its schedule. The 1914 season finale at Oregon State was the first against a major college opponent since a 1905 loss at Stanford, and was also USC's first game ever outside of California. The highlight of Glaze's brief tenure occurred the following year with the inauguration of the long-standing series with California. At the time, Cal was considered the traditionally dominant team of West Coast football, and Glaze managed to lead USC to a 28–10 road victory before falling to Cal, 23–21, at home later the same season; however, it was Cal's first year resuming football after having switched to rugby for the previous nine seasons.
