I like the idea of expanding to include Iowa State or Missouri. That leaves a spot in the XII for Arkansas, which belongs with its SWC brothers from Texas.
Beg to disagree. The University of Texas, who has a lot of clout in the Big XII, does not really want Arkansas in the conference. Texas A&M, another big powerbroker in the Big XII, does not really want Arkansas in either. The reason why is that both of these big Texas schools have always suspected Arkansas of cheating to get Texas recruits, and they didn't like it that many Texas recruits chose Arkansas over them. The two might be willing to play Arkansas OOC, but they will not let them into the Big XII.
As a replacement for the SEC, that gets difficult. I think FSU would be the logical choice, but it will not happen as long as Bowden is around. Remember he was the one who said it would be too difficult to win NCs in the SEC, so he joined the ACC. Clemson will never happen as long as Carolina has a say in the decision.
VT might be interesting even though they are down this year. They might even consider it as a preemptive move if Miami goes to the ACC.
Or, how about Miami to the SEC? A very long shot.
Agree on FSU. Also, there would be two other schools (possibly three) that would be opposed to Clemson's admission to the SEC besides South Carolina. Georgia does not want Clemson either, and I seriously doubt that Auburn would want them in either. The reason you ask? All three schools recruit Georgia heavily, and Georgia and Auburn do not want another SEC school gobbling up Georgia recruits. You could also add Tennessee to that mix also.
Now for the other two schools, Miami and VT. Both schools have a better chance at getting into the SEC than Clemson. Of the two, I think Miami has the better shot at getting into the SEC. The SEC wants more Florida recruits and the addition of Miami would help that goal. Also, the SEC has an intense dislike of the ACC, and would love to make sure that the ACC would not be much of a factor on the BCS scene. The addition of Miami would accomplish that. Plus, VT has made it known that it would love to be in the ACC, but VT is opposed by, not by UVa, but the four Carolina schools.
At the same time, there is a lot of resistance in the ACC in the subject of giving Miami membership. Look for the SEC to take advantage of the situation, and look for Mississippi State to get the boot from the SEC (the only shocking move I will predict!!)
