I actually don't expect alot more movement, simply because there are few assets worth purchasing.
There was an article today where a B10 AD is quoted as saying that Washington and Oregon, while having some value, are not worth a full share of the new B10 contract. So at least for now it appears like neither is likely to get a B10 invite in the immediate future. If those 2 schools are not seen as adding enough value how many schools are, I expect it may be enough to count on one hand.
Fans of every school are clamoring to get into the Big 2, but realistically there may not be more than another 2-4 that ultimately get invites. Those conferences are only going to extend an invitation if they think it is additive to their contract.
Fans keep thinking how big the SEC and B10 will become, when they may need to think more in terms of how small they may remain. There is no guarantee they even go to 20 teams. Maybe they stay at 16, maybe they go to 18. There is no guarantee they have an appetite for a 20+ league conference and right now it feels like it will be less than that.
The one truly valuable brand out there is ND. I don't think B10 will do anything else until they know what ND is going to do. If they truly want ND then I could see them taking Stanford as well as that would then bring the 5 biggest rivals for ND into the same conference. Their FB program is not part of the ACC's GoR, though their other sports are, so they are the one school that could relatively easily make the change an have limited repurcussions.
