Tulsa

From 1941 to 1945, Frnka coached at the University of Tulsa, and compiled a 40–9–1 record. The Tulsa Golden Hurricane had never been to a bowl game before, and he took them to five straight, becoming Tulsa's most prolific coach. The Golden Hurricane won three league titles, and outscored opponents 1,552 to 375. He led the team to their first bowl game and a school-best national ranking of No. 4 at the end of the 1942 season.

Tulane

From 1946 to 1951, Frnka coached at Tulane University, and compiled a 31–23–4 record. Since the 1920s, the Tulane Green Wave had been a national power in college football, and Frnka-led teams produced records of 9–1 in 1948, 7–2–1 in 1949, and 6–2–1 in 1950. In a 1949 issue devoted to a preview of that year's college football season, SPORT magazine declared that Tulane was the best team in the country.
