I thought about that earlier and I don't think it's completely out of the realm of possibilities. All that needs to happen is Texas and Oklahoma beats MU and ku which is what should happen. Then Iowa St. needs to beat an offensively challenged NU team that might have a first time starter at QB. Iowa St. is riding high after smoking Baylor(see fatty's chills thread) and they are no push over this year. The odds are against them but I wouldn't be completely shocked because NU just can't score.
And obviously, KSU needs to beat Colorado which they are favored to do at home.
The standings would look like this:
1. Kansas State 3-1
2. Iowa State 2-2
3. Colorado 1-2
4. Nebraska 1-2
5. Kansas 1-2
6. Missouri 0-3
At that point, with the tiebreaker held over ISU, the North would truly be KSU's to lose.
