IOWA CITY, Iowa (AP) – Iowa was let down by its offense, defense and special teams against Minnesota last week and wound up with one of the worst losses of Kirk Ferentz’s 13-year tenure as coach.  Iowa hosts Michigan (7-1, 3-1 Big Ten) on Saturday looking to bounce back from a stunning 22-21 loss to the Gophers. Ferentz says it was his fault the Gophers recovered an onside kick that led to the winning touchdown because he failed to call timeout just before the kick.  Ferentz also says the Hawkeyes (5-3, 2-2) aren’t playing defense well enough. The Hawkeyes need just one win in their last four games to earn bowl eligibility.
