Tennessee lost to Georgia State. This is a thing that happened.
If you don’t watch college football, compare it to an extremely low level USL team beating what used to be a good a MLS team.
The major difference here though is that when the USL team beats an MLS team in real life —although still in fact, very funny— they get nothing other than some bragging rights and a chance to move on in a tournament that, as an Atlanta United fan, is possibly the single greatest tournament to ever exist and definitely should not be made fun of.
