The result might not end up being very fearful, but at least they come to play. They should be feared. Iowa likes to lose to teams that have "something to prove". NW, ISU, Minny, etc.
That's because those teams circle Iowa on the calendar. Iowa it seems just crosses those teams off. However, I don't think any FBS school fears those schools or any school just because they show up to play, they may respect them though. The players wouldn't be playing football at their school if they feared another team that they play regularly.
