No, I don't think I would, Jason and here is why.
1. Missouri stands to make more money in the next 5 years then Nebraska from the new agreement that the Big XII is making
2. The old rivalries would still be in check
3. Missouri, like Nebraska, would be in the middle of the pack in the Big Ten in football. In the Big XII it stands to reason it should be one of the top 3-4.
4. With the elimination of the B12CG in FB there is now no reason that KU can do some backyard swindling to jump into a BCS game when the toughest team they played all season, THEY LOST TO.
5. Big Ten will be MUCH TOUGHER for Nebraska in the "other sports" -- ie Volleyball, Gymnastics, Wrestling -- the sports that NU actually WINS conference championships in.

Is that enough reasons or do you need more, Jason?
