After a half-season scramble resembling a bowl of vegetable soup and not its traditional steak-and-potatoes recipe, the Big Ten might have returned to its normal diet Saturday.

Wisconsin steamrolled Purdue 38-14 with a 467-yard rushing performance. Iowa and Michigan State engaged in their traditional slugfest with the Hawkeyes pulling out a 19-16 double-overtime victory. And Michigan posted its first shutout this season while blanking Illinois 45-0.

With Ohio State and Penn State ineligible for the postseason, Wisconsin (5-2, 2-1) and Purdue (3-3, 0-2) were earmarked as the favorites to represent the Leaders Division at the Big Ten title game. The Badgers turned that game into a rout behind Montee Ball’s career-high 267 rushing yards.

“This was the game we were looking for,” Ball said. “We practiced really well coming into this game, and we’ve been getting better and better. This was a great win in the Leaders Division. We just need to keep carrying this momentum from day to day.”

Iowa (4-2, 2-0) earned its second straight Legends Division victory and fought blow-for-blow with the league’s most physical team. The Hawkeyes wanted to send a message that they can match any team’s toughness, and they did so in East Lansing.

“That’s what we preach here,” Iowa wide receiver Keenan Davis said. “We’ve got to be the most physical team. We don’t really have the most athletic guys, but that’s why we take physicality into it. That and playing smart. Being detailed. We have to do those things to be a good Iowa team.”

Iowa prides itself on not looking ahead, focusing narrowly and not getting caught up in the big picture. That philosophy will serve them well, unlike other divisional foes who openly discuss winning out to stay in the Rose Bowl race.

“What we’ve tried to do is focus on what’s right in front of us and getting better,” Iowa Coach Kirk Ferentz said. “That’s what this game is all about and that’s what it teaches you. You’ve got to have some mental toughness to do that because not every day is going to go the way you want, every play is not going to go the way you want and (Saturday) was a great illustration of that.”

Michigan (4-2, 2-0) gave up just 134 yards against Illinois. Quarterback Denard Robinson rushed for two touchdowns and threw two more to keep the Wolverines in a first-place Legends Division tie with the Hawkeyes. Michigan and Iowa meet Nov. 17 in Ann Arbor.

“I thought (Robinson) did a nice job managing the game,” Michigan Coach Brady Hoke said. “His reads were good. I thought we were in and out of the huddle, which gave him time to check a play if we wanted to do that. I thought he ran the ball hard and that’s one thing that you love to see. He’s not afraid, and he did a nice job for us.”

Ohio State (7-0, 3-0) held off a pesky challenge from Indiana 52-49. The Hoosiers recovered an onside kick, scored a touchdown and a 2-point conversion inside of two minutes remaining but Ohio State recovered the ensuing onside attempt to end the threat.

“We are not good in certain areas and we were exposed,” Ohio State Coach Urban Meyer said. “Spread offensives right now are really exposing us right now. We have got to get something fixed”
