There is a 0% chance we take anyone with academics that are lesser than OU(OU would be at the lower end and might not make it themselves but I would make the exception)
I am all about expanding the football recruiting area since expanding within the footprint does nothing(Adding ND adds nothing to Big Ten football but shiny helmets and some extra money)
I'm all for keeping ND out and going with talent rich states like Virginia or even Maryland/DC. Texas would be the easy choice for me(even though OSU doesn't recruit Texas).
1. Texas(great academics and great recruiting state)
2. UVA(great academics and good recruiting state)
3. VaTech(good academics and good recruiting state)
4. GaTech(great academics and great recruiting state with a northern-esque city since Atlanta is filled with northerners)
5. Maryland(good academics and the DC area is a very nice recruiting area)
6. Oklahoma(lower end of academics but they are improving and a top 5 program that is only 3 hours from Dallas)
7. Kansas(bad football but they are a good school and the basketball is top 5 all time)
Despite your personal hate to ND that most of us also share, you put ND on the top of that and I would say that would be a reasonable list of teams that the BIG presidents would go after for expansion. Maybe throw BC and Rutgers in the bottom five of that as well. Yea, ND has been sucking for quite a while now but they still have a very relevant national following. If they finally gave in to being equal partners, I have no doubt the BIG would take them in a heartbeat.
The next move may be up to the SEC. They will be at 14. I think the BIG is fine with 12 but if the SEC would go to 16, I think it would force everyone to get to that number and the mad scramble to the super conferences begins.
For this list I actually am putting my dislike aside.
If you bring in ND you will find that nothing will improve outside of the money and we already have the top 3 fanbases in the country and huge alumni/fan bases in Wisky,Nebraska,Sparty and Iowa(probably all in the top 15-20)
Recruiting? Chicagoland IS Big Ten recruiting territory.
Competition? I will take at least 6 current Big Ten teams over ND's past 15 years. They add very little outside of being a fantastic school and having the #4 fanbase in the country.
Give me VaTech and UVA. Great connections for the Big Ten in terms of accessing southern talent while still retaining a northern identity(VA is a southern state but culturally they are very mixed) and then we also get one top5 Public school and a pretty good school who has a better program than ND.
