Behind LSU and MSU, I hate Vandy next most, so I'm pulling for UVA.
I'm unique though. Most people don't hate Vandy. I just hate Vandy because their fans want to pretend to be above the crazy obsession with sports in the SEC. Therefore, I don't think they deserve to win at anything.
You don't get to put a lot of effort into winning, and then when you lose pretend you really don't care, or that you're above caring if you win.
Everyone played pick up basketball or something with a kid like that in your neighborhood. Once you started kicking his butt, he acted like he really didn't care, but if he beat you, he did care. That's Vandy fans, and therefore I hope they lose.
The whole "losing to the national champion" thing for me comes well below the hatred for Vandy in my reasons for pulling for UVA.
