Even if Texas had a Greg Hatcher type that wants to fund the college program for the first few years, I still don't think it would be enough to sway the powers to be at D1 school.
UT recently had the opportunity to add a men's & women's program, but they declined. The money was raised, but they still said no.
It would not surprise me if it was 20 years before a big D1 school in Texas adds a men's program.
