Public donations require 2 things: the athletic department has to reach out to the public, and they have to provide an incentive for donating. Tennessee loves Butch Jones and they are happy to be relevant again. They believe he is good for the long-term of the program. Donating is easy.
If the GTAA wants a publicly funded locker room, or anything else for that matter, it just takes providing a reason to donate - what the locker room will contribute to - and reaching out. I haven't gotten any calls about it.
Are they really relevant though? They lost to the two best teams they have played and had to beat the mutts by a Hail Mary and we know Georgia isn't a good team this year.
