I think the starting point would be marketing with TCC students, NSU Students, NEO, Langston, Bacone etc. Making it an cool/fun experience for them and getting student age attendance numbers up first then working on the older fans. Having such a small student body, and alum is always going to be an uphill battle for attendance battling OU, and OSU for butts in the seats.
Something is not working in the marketing department though. My wife is a TU, and OU alum. TU only hit us up for donations. We never hear a word about tickets for any sporting event.
We always hear from OSU (where I went), and OU about tickets, and specials etc.
