I think ISU's only chance of going to the Big 10 is if they decide to go to 16 teams. If they decide to add that many teams, they can afford to add a school like ISU that doesn't necessarily bring much other than regional rivalries, especially if they add Missouri and Nebraska. However, I'd say there's a 99% chance the Big 10 doesn't go to 16, and I'd say anyone expecting them expanding to 14 is going way out on a limb.
