The Ergens do support UT-- not always visibly and not as much as some think they should, given their financial position. Ditto other big-name families like the Andersons and the Kaos. A lot of their support is specifically earmarked for academics, endowments and facilities. UT's donor fatigue has been escalating. People are very tired of committing huge sums to support-- and too frequently bail out-- UTAD. A decade of bad decision-making wears on people, especially when the symptoms continue to negatively impact the university.
The pullback goes down to mid- and lower-level donors, who're wanting to earmark contributions for other sports and academics. Being discouraged from doing that doesn't go over well. Donors pushed hard for LNS renos -- which were9261290989407830055302 more popular than Neyland renos. Donors won that one-- to a degree.
