I'm not even shocked at all at the fact that Iowa is getting blown out by the Vols at this point. They've only really been able to beat either bad teams, and even then, a 2-10 Iowa State that was blown out by both Oklahoma and TCU beat the Hawkeyes. They've only been close against average teams, and the only team they blew out was a bad Northwestern. You could argue that they had a chance to beat both Nebraska and Wisconsin (two of the best teams they faced all year), but they still lost. And they got blown out by Minnesota on top of it. Take a fairly mediocre team and put them against a hungry SEC Team with a program on the rebound, and you get this.
If this result holds up (which, unless Iowa has a miracle comeback, it will), the Big Ten will be at 5-5 in the bowl season at the time of my post. The SEC will wind up at 6-5 after Tennessee finishes their romping on Iowa (again, at the time of my post). As of right now, the ACC (4-7 at the time of my post) and the Big 12 (1-4 at this time AFAIK) are the losers in this bowl season. But if I'm wrong, someone let me know so that I can correct it.
