I looked at Purdue's 5 and thought, "That's low." I looked at Purdue's schedule, and then thought, "That's about right."
I view Iowa as a 9-win team this season, because of the schedule, and my thought Clayton Thorson won't be moving so well, if he even plays. But Maryland and Iowa State could sneak out wins in Iowa City. Penn State and Wisconsin will be formidable, but Penn State will probably not be as formidable as the past 2-years, so there is a possible road win for Iowa. I suppose 8.5 would be a more accurate win projection, but Iowa has never won 8.5 games.
