The foes keep getting more fearsome as October opens for the Buckeyes. Iowa, fresh off a 31-14 win over Minnesota to take back control of the Floyd of Rosedale and open Big Ten play with a win, enters Columbus eager to provide No. 3 Ohio State with its toughest test to date. The Hawkeyes, who improved to 3-1 with their win over Minnesota, will also have fresh legs coming off a bye last week.
