Day bowl games. The Golden Hurricane also was handed one of the worst defeats in college football history when they were beaten in regular season play by Houston Cougars 100–6 on November 23, 1968. Dr. Phil McGraw played for TU at the time. Vince Carillot succeeded Dobbs as head coach. However, he resigned after only one season, a 1–9 campaign in 1969, after an NCAA probe into possible infractions that occurred under his watch. In July 1970, Claude Gibson was elevated to interim head coach when Golden Hurricane coach Vince Carillot resigned. When Gibson's Tulsa squad started the season 4–1, which included a stunning upset of Memphis, a team Tulsa had not beaten in six years, the interim label was removed. His first Golden Hurricane team finished 6–4. However, a 4–7 record in 1971 and a 1–5 start to the 1972 season did him in, as he was fired. F. A. Dry was donned the interim tag when Gibson was fired, and a 3–2 finish to the 1972 season earned him the permanent head coaching position. Dry's Hurricane compiled records of 6–5 in 1973, 8–3 in 1974, 7–4 in 1975, and 7–4–1 in 1976 for a total of 31–18–1.

At Tulsa, he compiled a 56–32 record with five Missouri Valley Conference titles. Cooper considers his tenure at Tulsa his "most enjoyable years as a coach". For most of his tenure, Tulsa had trouble attracting enough fans to meet the minimum requirements to stay in Division I-A, and were forced to pad their gates. While they claimed to have attracted over 35,000 people per game, the actual average attendance was closer to 17,000. Cooper departed Tulsa after the 1984 season to accept the position of head football coach at Arizona State. Don Morton era (1985–1986) North Dakota State head coach Don Morton was hired to replace Cooper in 1985. Under Morton's tutelage, the Hurricane compiled a record of 13–9. The Missouri Valley dropped football after the 1985 season. Tulsa, by this time the MVC's only Division I-A member in football, became an independent. Morton left Tulsa after two seasons to accept the head football coach position at Wisconsin. On November 2, 1985, Tulsa became the first NCAA football team
