I think if they were going to expand, they could probably more easily do it with D1(ish) schools that are not fully entrenched in Big 5 conferences – like Notre Dame, Georgetown, Rice and JHU – or D3 schools like MIT, UChicago, Wash U and Emory.
Let’s see here:
Notre Dame is a partial member of the ACC. They have historically valued their independence. And they are major D1 – probably a “no”.
Georgetown might be more likely than ND – they are an historic program in basketball, but since the Ivy League is D1 in basketball, they can at least still play in the NCAA Tourney. They could probably make the transition. Call it a Yes.
Rice is D1, but they suck in football, so maybe they wouldn’t mind dropping to FCS in that sport. They do have a very good baseball program – not sure if that would be enough to keep them out of the Ivy. Distance and heat could also be an issue. Call it a “no”.
JHU is D1 in lacrosse, currently in the B1G in that sport. The Ivy has some decent lacrosse teams, so the transition might not be too harsh. They would have to up their level in some other sports. Let’s say they do it.
UChicago, MIT, CMU, Wash U and Emory – all are D3 and would really have to bring their recruiting and facilities up to be able to compete in the Ivy League. They would be doormats the first few years, at least. Just for fun, let’s say MIT and UChicago are invited and accept.
So imagine this as the expanded 12-school Ivy League:
Harvard
Yale
Princeton
MIT
UChicago
Columbia
Penn
Brown
Cornell
Dartmouth
Georgetown
Johns Hopkins
Not bad.
Georgetown would be a marquee name to boost the league’s basketball visibility and competitiveness and JHU would do the same for la crosse. All four schools would add their considerable academic quality and reputations to the league, obviously, as well.
