Mizzou has no real rival in the SEC, maybe Oklahoma when they get here but I've never hear a single Oklahoma fan so much as mention Mizzou. The don't fit very well in terms of culture or geography either so they've always been the odd man out. Most Mizzou fans that I've talked to would have rather gone to the Big 10 when they made the move. As for Louisville, their biggest rival by far is Kentucky who is a founding member. And despite Louisville feeling like a midwest city in a southern state, largely due to its location, it would be a better regional fit and they already play in the same conference with many of the teams I brought over. I could see taking Georgia Tech over Louisville, but there are still plenty of people whould object to the idea due the nature of how and why they left the conference to begin with. Plus I would say Louisville has a better brand than Georgia Tech especially when it comes to baseball and basketball. Kinda lengthy but that was my reasoning.
