As someone else already stated, both teams have a game between then and now and we will know more about each team in just over a week. A great deal would hinge on what if any injuries might take place between now and then also. We know what Iowa will try to do, run the ball (ball control drives) and try to wear down breaking a couple long ones. Mixing in some throws to Wadley or Butler to get them out in space and trying to get missed tackles. ISU will try to pass I believe as the WRs should be able to test Iowa's secondary. Will Park have time to get off good throws? Park is not a run threat like Lanning so that is one limiting thing. And then throw in there how turnovers go.
My prediction before week 1 is that Iowa will win by 10 or so. It will be interesting after week 1 how people then feel.
