Yes, Leman, OBK and Granger the Guru if you can get his attention. They would all make good references in your work.
Did you play in Texas? Is it the focus of your paper? Either way if it's about the history of the game early on you need to address Epler in Nebraska, 1934. The first game in Texas. National popularity into the 1950's. Texas first game, state championships starting in the early 1970's. Teams with multiple championships. Great players from Jack Pardee to Grayson Rigdon. Great coaches. Maybe interview a few. Lee of Strawn, Reed at Gordon, recently retired Richey of Borden County or current coach there Steele, recently retired Crawford of Abbott. Any of these would add credence to the effort. Food for thought.
