How about kansas and iowa st yuck or kansas and virginia
Iowa and the Big Ten have stated multiple times basically that ISU is never getting in. They have that market locked up only Mizzou/KU could really lock it down fully.
As far as Kansas to the B1G, it won't happen till 2025. The Big 12 grant of right (where the conference owns each individual schools TV rights) doesn't expire until then, so if they move the B1G would get no benefit from KU home games. The B1G/PAC12 also have GORs. Only the ACC/SEC do not in the Big 5, and the SEC may be signing one soon for their network.
The only way any team from the Big 12 can leave is if 60% of the schools vote to break the GOR, so the B1G would have to take Texas (tier 1, AAU), OU (Tier 1), KU (Tier 1 AAU), and ISU (Tier 1 AAU) plus 2 less than stellar academic schools like TXTech (Tier 2), OSU (Tier 2), WVU (Tier 3) or KSU (Tier 3) so its unlikely, the PAC12 might take TX/TT/OU/OSU/KU/KSU to get to 18 but that because they are landlocked and the B1G is not.
Also the B1G cannot work with another conference to break up the Big12 or risk a big lawsuit (anti-trust, collusion, tortuous interferance, etc.). Also if I recall correctly, KU cant leave KSU per some state law (not sure if enforcable or not).
The only immediate options for the Big 10 outside of the ACC/ND and UConn are Mizzou and Kentucky but both are considered extremely longshots at best.
Tka - when I posted earlier, I had not scrolled up far enough. You made much of the similar points in an elaborative way. Certainly, collusions with break-ups can generate ramifications.
What is seen with so much of expansion and re-alignment, is taking advantage (or not taking advantage) as opportunities, with the right timing, present themselves. While certain conferences may have their wish lists, that are subject to certain revisions, I have not seen any of them put out a grand design, saying what they want to look like in 2015, or 2020, with named new aquisitions included. Can it be said the B1G had a 5 year or 10 year plan to acquire specifically Maryland and Rutgers at the exclusion of others? I don't think so, though certain names get batted about for years beforehand by all sorts of pundits. Did the SEC have a long-term plan to take Texas A&M and Mizzou? With A&M, there's enough evidence to say yes. Mizzou seemed like a short pondering time, arising from opportunity and an immediate balancing need.
While the expansion issue remains fluid, I hope the B1G and the SEC give it a rest. If they do go to 16, next so many will be talking about 18 or 20 or 24. So much is becoming pure greed surpassing practicality. Dividing up the B12 and/or the ACC to establish 4 national SECTORS of odd-shaped clusters of prime sports schools is suppose to be a great enhancement for college sports? If this stuff does not get under control, a lot of regrets shall happen. Already, bowl attendance figures are down; and putting more strain on the "have-nots" and feeding the "haves" even better, they THINK they know the ultimate outcome.
