Iowa really struggled to start the year. Jok was back but they lost their other 4 starters. Jok and Dom Uhl are the only upper classmen on the roster who play. The rest are freshman and sophomores, only 2 of whom played roles of any significance last year. So they are a young team that took some time to develop. It really hurt they lost all their significant non-conference games except for Iowa State. I have no idea how you lose to Nebraska-Omaha - didn't even know they were Division 1.
But they are playing well right now. I think jncuse is right, they need to beat Penn State and win at least 2 in the tournament, if not 3 to make it.
