"Marginally behind several Big 10 schools"? I'm sorry, but that is called willful ignorance. Missouri is 31 spots behind the last Big Ten school in the academic rankings. That is totally unacceptable.
Pitt is the only possible choice, since Notre Dame will never join.
Why would we want some Big 12 cast-off dump school to join the first and most prestigious conference in the country?
Yes, in this instance I would consider 31 spots marginal. Academics are a consideration here, but you're kidding yourself if you think they're anywhere near the top of the list. What media markets it brings in is #1. Fit geographically and within rivalaries for athletics (that's what this is about) is #2. Missouri fits better then anyone on these two requirements except ND. Academics only become a factor if the school under consideration is well below the standards of the rest of the conference, or when splitting hairs between two otherwise equal candidates. Missouri is not WAY below the academic standards of the rest of the conference. For one example, they have an excellent journalism program. It's not as good as Northwestern, but it would easily be the 2nd best in the conference.
