Before the B10 contract and related ability to add teams and not dilute money, I was a bit skeptical that B10 had any good reason to add anybody not-named Notre Dame. But with their TV partners willing to pay equal money for Cal, Standford, Ore. U, and Washington. . . it really seems like it should happen. That's a shift in the landscape, at least from my perspective.
I've moved from thinking not much more was likely to happen any time soon to believing significant changes before the end of the football season are likely.
