I don't see a large enough skill gap between the acc and big east to justy one league be in the FCS and not te other. I really think the best three conferences are big XII, SEC, and big10 but after that I feel the leagues aren't the different.
Our "FCS" team in 4 seasons has toppled FSU, Auburn, Clemson, Kansas, Miami, Notre Dame. These are all "big 5" schools. How many average teams can list this many OOC wins like this in against big 5 schools in their last 4 seasons?
If Slive really believes this because of a talent gap he's insane. I could see him wanting it only to reduce competition. I don't think it will ever happen.
