Someone yesterday on ESPN's Big Ten blog suggested the league add Kansas, Syracuse, Duke, and North Carolina to become a more solid basketball league. The blogger, Adam Rittenberg basically said it would work from a basketball standpoint, but the biggest dollars come from football, so it wouldn't be the greatest idea overall considering how Duke and KU's programs have been.
I've heard the Maryland rumor as well, and I believe that if super-conferences are the way to go, Notre Dame will have to consider the B1G again, especially if the ACC crumbles (the league ND said they "preferred" a few years ago). I keep reading things that say the league is very content with 12 and they won't add just for the sake of adding, but everyone knows Notre Dame is still their pipe dream and a school right next to DC would be a great market to add. I think academics still matter somewhat too, but that might be propaganda I've read. I'd still be curious to know if Missouri looks any more appealing if they decide they "need" to hit 16.
