Though Payton had established himself as one of Mississippi's best running back prospects, he received no invitations from Southeastern Conference colleges or universities, which were accepting only a few black players at the time. After originally committing to Kansas State University, he decided to pursue his collegiate career at the historically black, Jackson State University, Jackson, Mississippi, where his older brother Eddie played football (contrary to popular belief, he was never recruited by the University of Kansas, according to then coach Don Fambrough[12] as Payton claimed in his autobiography[13]).
