Ohio State will host Iowa on Saturday (3:30 p.m. ET; CBS) and the No. 3 Buckeyes (4-0, 1-0 Big Ten) are down to being a 20.5-point favorite over the Hawkeyes (3-1, 1-0). The spread opened at 23, quickly dropped to 21.5 and continues to move Iowa’s way. Do we expect this to be a tight contest for Ohio State, or will the Buckeyes be able to overwhelm a very solid Hawkeye squad?
