Louisville never really had a chance, though. The whole basis of the conference realignment was to to bring in larger, higher population media markets in states that were new and previously unoccupied by the SEC, with the goal being to drive up the amount of TV money a network like ESPN would be paying the conference to have the rights for the major local college teams' games (over the footprint states/areas).
Unfortunately, Virginia Tech nixed/killed any idea of their joining the conference (repeatedly, actually) during the beginning of the SEC's search for a potential 14th team.
The likely only other option in that round of conference expansion was West Virginia, and had the SEC gone that route, the schools would also be getting a lot less yearly money from the SEC Network TV contract with ESPN.(and as a side effect, South Carolina would have played for another SEC Championship)
