Like I said, if the SEC wants Florida St they will invite them. If they don't, the affiliation with Florida doesn't really mean a lot.
Since 2006 only two conferences have won national titles. The ACC and the SEC.
You don't think a Florida St/Clemson matchup is a big draw? Yes currently the ACC is far behind the Big 10. It hasn't always been that way. The old ACC looked like a great conference when they first became one.
How about Miami and all of their titles in the Big East?
