They are making sure their preference for joining the Big 10 is getting media play today. I'm a bit surprised the SEC is letting Mizzou make them look like a consolation prize.
Yes. At that time, they didn't really have any other option. I think they're trying create a scenario where the Big 10 chooses to take them now because they won't be available if they wait.
I don't think the Big 10 wants them. I don't really care that they are making the SEC look "second tier." When they're done making asses of themselves, perhaps they'll get their SEC invite.
