Yeah but you make it sound like any team could do that. And the simple truth is, not every team could. If Louisville had done the same thing that FSU had done this year would the SEC invite Louisville in? Eh.
People forget that it was Bobby Bowden who wanted to join the ACC over the SEC back in the 90s because he thought it was an easier route to a National championship. And, the money was just as good for the ACC back then.
Around that same time, the SWC was dying and the SEC and A&M had eyes on each other then because RC Slocum wanted to move to get bigger than Texas, or at least out of it's shadow. Politically, the schools and state were not ready for it so both Texas schools joined the Big 12. But when the Longhorns cut their own network deal, that was the last straw and the SEC happily took A&M. For the entire program, the move has been hugely successful for A&M in recruiting and revenue in all sports. Over that time, the Aggies have won more football games than Texas, and have had a higher profile nationally with more big wins. Until this season.
Florida St. Has been sitting there the whole time. But the SEC now has the two biggest programs in the state of Texas, and Oklahoma who has an even greater history than Florida St. They had their shot at the SEC who moved on to bigger fish.
