Don't forget, kiddies: the Big Ten Conference is an academic community as well as a means of organizing a series of sporting events. Because of this, I'm willing to go on-record as saying that because of their exceptionally poor academic rankings/standards that there is NO WAY Cincinnati, Kentucky or West Virginia will be offered admission to the Big Ten. Mizzou and Nebraska are no prizes, either, though they could be considered... they aren't nearly as bad.
BC, UConn, Rutgers and Syracuse are probably the best choices, but they're pretty pedestrian in terms of their overall sports history (especially football). Notre Dame is the best and most obvious choice, but that isn't happening... sigh.
