This is not the most intellectual of answers but I only care about expansion as it concerns my ability to see -- in person -- my football team play more often. Therefore, I would be against any expansion of the league where I can drive to New York City quicker than I can get to the new expansion school. Texas A&M and South Florida would be out for me. I would be in favor of Clemson and VA Tech if only for those reasons, but to be quite honest I am happy with things now. I agree on Arkansas. I had free tickets for a game there when we were actually good, and I turned it down because the trip is just too much in one weekend. These are entirely selfish answers but that's where I am at right now.
