I grew up in the 90s but I was an anomaly in that even then I realized that Alabama was the real enemy. Florida is a strong and compelling second with a case to be made for being the team worth hating the most. With Alabama I hate a lot of their fans and Saban, but generally their players conduct themselves well. With Florida, their players are always the biggest pricks imaginable. They always have a few guys who deserve to be taken down a few pegs. I hate the Dawgs too but fail to see how they could be anywhere near as hated as Bama or Florida. The only exception is if you lived in Georgia.
The UT hate chart should look like this. Alabama >Florida>>>>>>>>Georgia.
