re: When will the Big 12, 10, and SEC break away?

Right now the Big 12 is worth about 30 million dollars less per team than the SEC. The SEC will land a huge deal with ESPN on the next go around and the Big 10 will do the same with Fox.

As we saw with the Pac 12, ESPN is not going to sign large contracts with anyone but the SEC. The Big 12 and ACC (minus FSU, NC, Miami, Duke and Clemson) will be reduced to "streaming" contracts this next go round as the SEC and Big 10 will get the lionshare.

This will facilitate the Big 10 and SEC to leave the NCAA and for ESPN and Fox to control major bowl programming and an Inivitational Basketball Tournament.
