The Big Ten entered the season with two ways to improve its national image. The first called for a veteran-laden Ohio State team with 20 returning starters to finish what it started the previous two years and win a national championship. The other option ultimately was more important to the league's long-term health, but seemed difficult.
Other teams needed to show they could close the gap with the Buckeyes and compete well on the national stage. If Ohio State was far and away the class of the league but continued to flop against elite opponents, national respect would be in short supply. Well, Ohio State flopped big-time on the grandest stage Saturday night, not even managing a touchdown against top-ranked USC in a 35-3 loss at the L.A. Coliseum. The Buckeyes will get Chris "Beanie" Wells back and still make a run for a BCS bowl, but the door is open for other Big Ten teams to carry the banner.
Wisconsin and Penn State certainly look up to the task. The Badgers claimed a gutsy road win against always-tough Fresno State and Penn State, despite weak competition so far, has simply blown teams away.
Here's a look at five lessons from Week 3:
1. Big Ten title goes through Madison --
1. Big Ten title goes through Madison --Wisconsin survived its biggest road test of the season by overcoming several obstacles, including the officials, at Fresno State. The power run game came through at critical moments and the defense, led by linebacker DeAndre Levy and tackle Jason Chapman, contained Tom Brandstater and the Bulldogs. The Badgers now benefit from a home schedule that includes Ohio State, Penn State and Illinois. Wisconsin hasn't lost at home under coach Bret Bielema.
2. Ohio State's offense needs more than Beanie -- There's no doubt Wells makes Ohio State a much better offense, not only from a productivity standpoint but because of the confidence he gives others and the on-field leadership he provides. But the USC game showed that the unit has several areas to repair. There's still not nearly enough creativity in the scheme. A veteran line crumbled against the Trojans, surrendering five sacks. And Todd Boeckman had another rough night when the team desperately needed strong quarterback play.
3. Fear the Lions -- The real season begins Sept. 27 against Illinois, but Penn State's offense has shown no signs of slowing down. Syracuse became the latest punching bag for Daryll Clark, Evan Royster and their teammates, as Penn State scored 35 points in less than 28 minutes. The Lions' road poise will determine how far they go this fall, as they travel to both Wisconsin and Ohio State, but there's little doubt the Spread HD offense makes them a much better team.
4. Purdue better, but still Purdue -- The Boilermakers' defense deserved better, as a top defender lamented as he stood outside Ross-Ade Stadium on Saturday night. Purdue showed it could keep pace with speedy Oregon, thanks to a much-improved secondary and strong line play from Alex Magee and Ryan Baker. But once again, Purdue couldn't come through in a big game. Quarterback Curtis Painter has had a fine career, but the signature win continues to elude him.
5. Defenses flex their muscles -- Ohio State couldn't stop Mark Sanchez and Michigan never got much chance to stop Notre Dame, but the rest of the league showcased its defensive prowess. Michigan State blanked Rusty Smith and Florida Atlantic in the rain, Iowa kept in-state rival Iowa State out of the end zone, Illinois needed a defensive touchdown by Brit Miller to outlast Louisiana-Lafayette and Northwestern continued to improve under new coordinator Mike Hankwitz. Purdue wasted a tremendous defensive performance against Oregon and Penn State continued to excel without Maurice Evans and Abe Koroma.
