The one league that seemed to not to be looking into expanding was the SEC what with their latest 15 year and nearly $3 billion television contract between ESPN and CBS.  SEC commissioner Mike Slive says their league is going to stay pat with their twelve members for the next year, but is going to be pro-active if super leagues start forming:

"Given the success we've experienced over the past decade, we are comfortable in the position in which we find ourselves," he said. "Having said that, if there's going to be a significant shift in the conference paradigm, the SEC will be strategic and thoughtful in order to maintain its position as one of the nation's premiere conferences."

The league is conducting internal studies about the expansion topic to weigh the pros and cons, but Slive has said no teams have been discussed.  This where the fun game of speculation comes in to try and pick out a few teams that the SEC would go after if they were to expand.  If the 16 team super conferences become a reality, the SEC should go for a home run and go after Texas, Texas A&M, Miami, and Florida State.   

Outside of landing the two Texas schools -- mainly University of Texas -- the SEC really has no benefit in expanding beyond what they have now.
