I know many, having lived in the Atlanta region since 1984. When I moved here, they were coming off their Herschel high. Then a very long stretch of meh set in, and Saban pretty much broke their will. So in my time here, it's only since they finally escaped Bama's stranglehold that they've become very cocky. Before then, they were basically Auburn.
The fact they had a fairly flawed team in 2024 and yet still beat us twice has them thinking we're not too special. And based on how we played against them, that's not an unreasonable conclusion. On their way to a title, they also somewhat recently destroyed a TCU team that spanked us. So UGA fans really do think they're much better at player development than we are, and they're convinced Texas is only returning to relevance because of money. Any other possibility would wreck their worldview.
I don't think they ever even wonder if they rebuilt their own program illegally. As a group, they really aren't deep thinkers about such things.
