My thoughts:
First, I think that taking any team in the league's existing footprint would be a bad idea. Thus, I am against Pitt, Cincy, and ISU. They may have the academics and even pretty good athletics but I think we want more states, not better penetration in existing states. Besides, I think that taking Pitt, Cincy, or ISU would be harmful for PSU, tOSU, or Iowa respectively. It would not surprise me if the AD's/Presidents of PSU, tOSU, and Iowa form a block by all agreeing to oppose the addition of any school in a current B1G State (or possibly any school not named ND).
Second, Notre Dame:
We all know that the Big Ten approached them decades ago. I don't like it NOW for several reasons. First, I think their brand is weakening rather than strengthening. Second, see above, same footprint. Granted, this is different for ND because their fandom is more national than regional but still, Indiana. Third, they aren't even close academically. They have great undergrad academics but the CIC and the academics that the B1G cares about aren't undergrad rankings they are Graduate Programs and Research MONEY and Notre Dame is a non-factor there.
After ruling out schools in current B1G States not named Notre Dame and ruling out Notre Dame, I would be looking for State Flagship Universities in nearby states and my preference would be for high-end academics, quality athletics, and fast-growing states. Thus, my list is:
- North Carolina: The state is #9 in pop with 10.5M and growing rapidly, the academics are great, and the athletics are pretty good.
- Virginia: The state is #12 in pop with 8.5M and growing faster than any current B1G state, the academics are great, and the athletics are decent. These first two I basically see as a package and I'd be willing to swap UVA for VaTech.
- Mizzou: The state is #18 in pop with 6.1M but slow growth. The academics and athletics are decent. I see this as a BIG drop from the top two.
- Colorado: The state is #21 in pop (just passed MN) and growing FAST. The academics and athletics are good.
- Kansas: The state is small and slow growing, #36 in pop and I honestly don't know much about the academics. The athletics are a mixed bag. They obviously have a great BB tradition (possibly #1 nationally) but the rest of their athletics are pretty weak.
Those are the only semi-local ones I would even consider.
Texas would be great as the state is #2 in pop with 29M and growing FAST and their academics and athletics are great. I'd be willing to take Oklahoma as a package with Texas particularly if we could get a commitment from them to improve their academics (which would probably just happen anyway with them in the B1G/CIC).
I've seen some chatter about West Coast schools and I just don't like the idea of raiding or effectively "merging" with the PAC. Apart from the possibility of a border raid (Colorado) I just think that the West Coast schools are too far away and that fan support out there is dubious at best.
