Will the agreements be enough to keep Missouri? We should know in the next 10 days. The decision appears to be in the unpredictable hands of Missouri’s board of curators.

Once Missouri decides whether to stay or go, the Big 12 has to figure out how much it wants to expand. If the Tigers stay, the league could remain at 10 teams. But that would probably be a point where it would explore potential revenue options.

Opinions are split in the Big 12 about whether Louisville or West Virginia would be a better fit for No. 10 if Missouri leaves. For now, give a slight edge to West Virginia because it is a better television draw.

How does T.C.U.’s decision affect Notre Dame? Sometimes amid the realignment frenzy, it is easy to focus on the chum instead of the fish. Notre Dame is one of the biggest fish in college sports, and a destabilized Big East may force its future toward a conference in football. The eyes of administrators around the country are on the Irish athletic director, Jack Swarbrick.

“Everyone is waiting for Jack to figure out what he’s going to do,” the Colonial Athletic Association commissioner, Tom Yeager, said.

The Irish will not be keen on staying in the Big East if the conference’s football side dissolves. Notre Dame has not entered discussions with the Atlantic Coast Conference or the Big Ten. But as the future of Big East football dims, the possibility of those conferences as landing places increases considerably.

The best possibility for Notre Dame is finding a partial landing spot in the A.C.C. That could mean Notre Dame’s basketball and non-revenue sports teams would become full-fledged A.C.C. members. In football, Notre Dame could set up a scheduling agreement with the A.C.C. in which it would play a certain number of the conference teams each season yet keep its football independence. Television executives believe that each Notre Dame game could be worth about $3 million for the league.
