Kind of a strange article suggesting that the Big 10 may try to add Notre Dame, Rutgers, Maryland, and...Georgia Tech? Seems strange, but if we assume that the Big 10 will only add AAU schools outside of current states then their only realistic options are:
Duke, Georgia Tech, Rutgers, Kansas, Maryland, North Carolina, Pittsburgh, Virginia
UNC and Duke are a package and they won't take both so they're out. That would leave:
Georgia Tech, Rutgers, Kansas, Maryland, Pittsburgh, Virginia
I hope Georgia Tech is out based on geography. Virginia or Kansas would fit much better in the Big 10.
I think you should look at a map. Eight of the twelve Big Ten schools are closer to Georgia Tech than to Rutgers. Only Penn State, Ohio State, Michigan, and Michigan State are closer to Rutgers. GTech brings the Atlanta metro area, and would be a great addition to the Big Ten.
Rutgers brings the NY metro area, and Maryland brings the Baltimore/DC metro areas. Both would be great additions as well.
But I'm not buying Notre Dame in the Big Ten - ever. ESPN might want it, but neither Notre Dame nor the Big Ten does. They've been down that road at least twice, and couldn't get it done, so there is no real point in pursuing it further. The athletics directors want Notre Dame in the Big Ten because it would be a great fit athletically and geographically, but the university presidents know that Notre Dame would be a terrible fit academically. All Big Ten schools are research heavyweights, while Notre Dame is primarily a teaching school - an outstanding one, but still. Notre Dame's focus is on undergraduate and professional (e.g., business, law) education; their doctoral program and research facilities are very limited, I believe.
Notre Dame wants to maintain their football independence and freedom. It's a point of pride for their alumni. They especially don't want to join the Big Ten. If forced to join a football conference, I believe they would choose the ACC or Big 12 instead of the Big Ten, because they would be able to retain more freedom - though probably not their television contract. Joining the Big Ten is like the Borg - you will be assimilated. Just ask Nebraska. In exchange for enormous amounts of both athletics money and research money, they must submit to some strong guidance from the Big Ten on governance, academics, and athletics. For example: raise your crappy men's basketball program up to Big Ten standards, hire a new coach, recruit better players, build a new arena - and make it a dual purpose arena because the Big Ten will begin sponsoring ice hockey in a couple years, etc. Now, Nebraska isn't complaining, because the rewards of Big Ten membership are far greater than any other conference has to offer, but . . . you WILL BE ASSIMILATED.
I have no idea who would be the 16th Big Ten school in this scenario, but I know that both Vanderbilt and Florida are AAU members. I've heard that UConn and NC State are close to being qualified for AAU membership, but I don't know whether it's true. I'll let others take it from there.
