Louisville has a solid contingent of BYU fans, and Indy and Nashville are only 2 and 3 hours away respectively, and both cities also have more BYU fans. I think it'd be fairly even in terms of fan support. When BYU played Marquette in Louisville in 2012, I remember that being the case, and Marquette was a 3 seed and is geographically closer to Louisville than most of Arkansas.
