Stan "Tex" Coleman never held the position of Commissioner in The League itself, but held the equivalent position in the rival Western League, and was instrumental in the merger of the two leagues, and the doubling of The League's size.

A retired senator from Texas, Tex Coleman was also an avowed football fanatic. In 1953, he organized his own franchise, dubbed the Dallas Aztecs, and petitioned The League to introduce a seventh team, which would open the state of Texas, and ultimately the Western United States, to expansion. However, then-League Commissioner Guy Cooper was not interested in expansion, and turned Coleman's offer down. Not to be outdone, Coleman gathered four other owners from around the West, and started their own league, dubbed the Western League. Coleman served as Commissioner of the Western League and also owner of the Aztecs.

Under Coleman's auspices, the Western League grew to become as competitive as The League, now dubbed the Eastern League. Guy Cooper's successor, David Kent, was willing to cooperate and organize exhibition games between teams in the two leagues. While this effort was set back by the death of the entire New York Shamrocks team following a battle of East-West champions, the efforts came back on track in the 1970's. Eventually, Kent and Coleman agreed to merge the two leagues, and reintroduce the two-division system of play that Marshall Cooper utilized decades earlier. Tex Coleman never became League Commissioner, and he presumably either took another position in the League office, or went back to oversee the Aztecs full-time.
