The toughest part of Ohio State's schedule is behind the Buckeyes. Troy Smith threw for 186 yards and four touchdowns and No. 1 Ohio State picked up its second road win over a ranked opponent by manhandling No. 13 Iowa 38-17 Saturday night. The Buckeyes (5-0, 2-0 Big Ten) faced three ranked teams in September -- Texas, Penn State and the Hawkeyes -- and beat them all by at least 17 points. Ohio State, which extended the nation's longest winning streak to 12 games, won't face another team currently ranked until their season finale against Michigan Nov. 18.
