The split-T is an offensive formation in American football that was popular in the 1940s and 1950s. Developed by Missouri Tigers head coach Don Faurot as a variation on the T formation, the split-T was first used in the 1941 season and allowed the Tigers to win all but their season-opening match against the Ohio State Buckeyes and the 1942 Sugar Bowl versus Fordham.Jim Tatum and Bud Wilkinson, who coached under Farout with the Iowa Pre-Flight Seahawks during World War II, brought the split-T to the Oklahoma Sooners in 1946. After Tatum left for Maryland in 1947, Wilkinson became the head coach and went on to win a record-setting 47 straight games and two national titles between 1953 and 1957.
In the basic or tight-T formation, three running backs would line up about five yards behind the quarterback. The offensive linemen would form a fairly tight group in front of the backs. In the split-T, the offensive line was spread out over almost twice as much ground. This prompted the defensive front to widen as well, which created gaps for the offense to exploit.
The original split-T was a full house backfield. Later, Faurot would set up a flanker on one sideline. This was done after experience with nine man lines showed the flanker to create issues for the defense. The use of a split end to aid the passing game was optional, and was not an integral feature of either the split-T or the tight-T.
