Jim Tatum
After World War II, Tatum accepted a position as the head coach at the University of Oklahoma. He compiled an 8–3 in 1946 record before accepting the head coaching position at the University of Maryland. Bud Wilkinson, a fellow assistant coach at the Iowa Pre-Flight School, was one of his assistants at Oklahoma and was promoted to head coach when Tatum left for Maryland.
Split-T
In 1946, Jim Tatum became the Oklahoma head coach. He installed the split-T offense that he had learned as an assistant coach under Don Faurot at the U.S. Navy's Iowa Pre-Flight school football team during World War II. In his first year, he turned around Oklahoma's losing record and delivered a Big Six Conference championship. In 1947, Tatum left Oklahoma for Maryland, where he saw even more success with the split-T, including a consensus national championship in 1953.
