At this point Nebraska's bowl picture looks pretty simple. There are 3 slots Nebraska could go to with The Cotton Bowl already saying it wants A&M.
Beat Oklahoma and it's The Fiesta Bowl in Glendale Arizona. Opponents would be either Connecticut (OH BOY!) West Virginia or Stanford.
Lose To Oklahoma the most likely destination would be the Insight.com Bowl in Tempe Arizona. Against Michigan
There is a chance that Nebraska could go to the Alamo Bowl in San Antonio if they lose to OU however the fact that the other team in the Alamo Bowl figures to be Arizona makes this possibility very slim. Nobody, not Nebraska, not Arizona, not the bowl folks, not ESPN wants to see these two teams play in a bowl game again after last year's 33-0 beatdown in the Holiday Bowl.
So basically if you're planning on going to the bowl game plan on a Phoenix suburb.
