The next few seasons saw average performances on the field. In 1929, the university hired Jack Sisco to coach the program. Sisco lead the team through some of its first years as a consistently-winning college football unit. The program won its first conference title in 1931 as members of the TIAA. In 1932, North Texas became a charter member of the new Lone Star Conference, compiling an 8–1–1 record, winning eight straight games after a 0–1–1 start, six of them via a shutout while allowing just 12 points against in that span. Sisco's tenure continued with conference championships in 1935, 1936, and a three-peat from 1939–-1941. Sisco was replaced by Lloyd Russell in 1942, who would only spend one season at the helm before the school temporarily disbanded its football program from 1943–1945 as many students went off to fight in World War II.
