IOWA CITY, Iowa (AP) — Iowa’s offense has been dreadful all season — and now the Hawkeyes are slipping on defense. Iowa (4-4, 2-2 Big Ten) has allowed 66 points in the past two weeks in losing decisively to Penn State and Northwestern. Though the Hawkeyes only need to split their last four games, it certainly feels as though the combination of a poor offense and a leaky defense has left them in serious trouble. Iowa travels this week to face Indiana (3-5, 1-3). Coach Kirk Ferentz says the defense needs to trust each other more and play better as a team.
