The Michigan/ gump game came up in a discussion at the end of the day at work. There are 3 guys in my dept...I'm 48, one guy is 40, the other is 28. I asked them which SEC team they hated the most. The 40 yr old said Florida and the youngest said Georgia. I'm guessing you're in your 20s. If I asked someone in their 70s, the answer would probably be Vanderbilt.
*I'm old enough to remember the SEC before the east/west divisions were formed. The TSIO was the game of the year. When the divisions were formed, Florida became our biggest rival to some, because we battled them for the eastern division title. I still don't consider Georgia a rival. I hate that they are better than us right now, but I don't loathe them like I do bama and florida.
*Having more hate for Michigan than Alabama, doesn't make sense, even with your examples. Are you from the north?
