I would want to play a team that doesn't already have a dedicated non-conference rival. So no GT, no Clemson, Louisville. Texas will be in the SEC in like two years so what's the point. I think VT is the most obvious candidate, UNC would be a nice one as well. UCLA was a good suggestion, I just struggle to see how a rival that's 1500 miles away is really feasible, there's just no real crossover of fanbases or anything like that. If Memphis continues to get better in football, that's not a bad idea, though they might be better suited for Ole Miss given the location of those two.
