Admittedly you should take this for what it's worth, but just got off the phone with a close friend of mine who knows someone who works at U. of Phoenix Stadium here in AZ (where the Fiesta Bowl will be played). Supposedly Iowa vs. Boise St. is a done deal, they have the invites (or whatever the proper procedure is) all signed and sealed, just waiting for Sunday to deliver.
I know it's stupid to believe 'I know a guy who heard from a guy who talked to someone', but every piece of information I hear down here alludes to Iowa vs. Boise St, from stadium people to airport people to radio people. Look me up for a drink when you're all in town... =)
