2. Pitt - ditto, rivals with PSU and OSU. Not a land-grant college, but enough history. Would PSU lobby against them, though?
3. ND - Good fit, but bad history - this has Bad Karma written all over it. I think this would be like marrying the high-maintenance prima-donna cheerleader from your high school days that dumped you for another guy a couple of times - years later, she's now had three kids and is divorced, broke, and running for financial cover. She's "settling" for you, and will never let you forget it. Too much recent bad blood here with the other Big Ten universities unless ND comes in gracefully and unconditionally both in public and in negotiations - unlikely.
4. West Virginia - Athletically good, state-college type school - but the lack of AAU certification will keep them out
5. UC. Too noveau-successful in sports other than men's basketball - and Big Ten schools don't consistently pack their successful football coaches off to other Big Ten -type colleges college because they can't afford to pay them enough. Until UC replaces Nippert (or plays at PBS) they can't generate enough money from football operations. Come back in ten more years, fellas.
6. Iowa State - right profile and location but second rate academically and athletically. No real gain for the Big Ten here.
7. (tie) Rutgers/Syracuse. Syracuse is private, Rutgers is athletically weak. Both are solid academically, but too far East. (PSU gets a bye here on "too far east" because State College PA is more remote and rural that any other Big Ten school.
9. (by a ton) - Louisville. The 'Ville is an overgrown commuter college, and is VERY weak academically.
