- Making Notre Dame Nervous - The only way for a 16 team conference to really work would be moving to a 10 game league schedule. You really wouldn't play the other side of the league often enough to call yourself a conference unless you went to 10 games. Ten league games for the Big 10 would mean extremely little scheduling flexibility for Midwestern teams in booking Notre Dame. Also, a 16 team Big 10 would eliminate the Big East. Currently, Notre Dame is guaranteed 4 games a year against Big East foes. Combine that with three more Big 10 teams, and it becomes hard to see how they would book a full slate of 12 games. There are only so many service academies.
- Making Nebraska Nervous - If the Big 10 takes Missouri and the Pac 10 takes Colorado, the team left standing in the Big 12's game of musical chairs is Nebraska. Texas and Texas A&M can do pretty much anything they want due to TV demographics and fan support. Nebraska doesn't have that luxury.
From there, all the leagues will take a deep breath. Because the contractual complexities of moving to 16 teams in one or more conferences are just too great. And University presidents are too risk adverse.
