What to watch in the Big Ten: Week 3

Posted by ESPN.com's Adam Rittenberg

Week 3 doesn't match its predecessor in terms of national prestige, but it still means a lot to the Big Ten. Wins over teams like Cal, Arizona and even Notre Dame would help the league's national reputation.

Here are 10 things you don't want to miss.

Spartans go for lucky seven -- The House that Rockne Built has turned into Spartan Stadium South, as Michigan State has claimed six consecutive games in South Bend. A seventh straight is crucial, especially after the Spartans lost their focus last week against Central Michigan. Notre Dame also comes in wounded and desperate for a victory, which could take some pressure off head coach Charlie Weis. Michigan State's secondary needs a much better effort against Notre Dame deep threats Golden Tate, Michael Floyd and Kyle Rudolph. Kirk Cousins could cement himself as the Spartans' starting quarterback with a big day.

Minnesota linebackers take on Cal's Best -- Led by reigning National Defensive Player of the Week Nate Triplett, the Gophers' linebacking corps has led an improved defense in two victories. But things get much harder this weekend as Heisman Trophy candidate Jahvid Best visits TCF Bank Stadium with eighth-ranked California. Minnesota gets a chance to show off its new stadium to the country against a top 10 team, but Best and backup Shane Vereen could make it a long day.

Iowa homecoming for Stoops -- Arizona head coach Mike Stoops returns to his alma mater with a pretty decent Wildcats team. The Iowa faithful undoubtedly will welcome the former All-Big Ten safety, but Stoops hopes to ruin their afternoon. Wildcats running back Nic Grigsby, the nation's second leading rusher, will match up against a Hawkeyes defense coming off a very impressive performance against Iowa State.

Buckeyes, Rockets clash in Cleveland -- What looked like a total mismatch before the season has spawned some more intriguing plotlines. Ohio State comes off a crushing loss to USC and needs to spark Terrelle Pryor and the offense against a Toledo team that has allowed 90 points in two games. If the Buckeyes can't score against this team, start to get concerned. Toledo, meanwhile, is riding high after thumping Colorado and boasts a dangerous quarterback in Aaron Opelt. Plus, head coaches Jim Tressel and Tim Beckman grew up together. And the game will be played at Cleveland Browns Stadium. I'm actually excited for this one.

Penn State ready to run -- The run game has been grounded so far in Happy Valley, and Penn State needs to get things corrected against Temple. Penn State boasts the Big Ten's best all-around back in Evan Royster, but the new faces on the offensive line have struggled a bit. The Lions can't afford to be one-dimensional when Iowa comes to town Sept. 26, so they need to spark Royster, Stephfon Green and the ground game right away.

Wildcats aim for Syracuse sweep -- The Big Ten is 2-0 against Syracuse this season, though the Orange have been a tougher opponent than many had expected. Northwestern barely squeaked by Eastern Michigan last week and needs a better performance from its defense against Greg Paulus and the Cuse. It's a critical game for the Wildcats, who need quarterback Mike Kafka to be a playmaker and defensive end Corey Wootton to return to the form he showed in 2008.

Wolverines reunite with English -- Michigan's veteran defenders face their former coordinator Ron English, who brings his Eastern Michigan team to the Big House. Players like safety Troy Woolfolk haven't forgotten English's intense style, and they'll look to impress him on Saturday. Michigan must guard against a letdown after an impressive start. Eastern Michigan showed last week that it doesn't quit, and the Wolverines need to maintain their focus to match their wins total from 2008.

Purdue's Bolden rolls along -- If you haven't watched Purdue running back Ralph Bolden yet, tune in to Saturday's game against Northern Illinois. The nation's leading rusher has been spectacular so far, averaging 7.1 yards per carry. Purdue has been a surprise team so far in the Big Ten, and the Boilers aim for a 2-1 start against a pretty decent Huskies team that gave Wisconsin all it could handle two weeks ago.

Indiana's defense hits the road -- Make no mistake. Indiana's trip to Akron is huge for Bill Lynch and the Hoosiers. IU hasn't been dominating so far, but it has found ways to win thanks to a veteran-laden defense. The Hoosiers need defensive ends Jammie Kirlew and Greg Middleton to apply pressure on Akron quarterback Chris Jacquemain, who has already thrown four touchdown passes to Deryn Bowser this year. If Indiana wants to make any sort of run in 2009, Akron is a must win.

Clay in the starting blocks -- Wisconsin's matchup against Wofford doesn't exactly get the blood flowing, but it's worth watching sophomore running back John Clay make his first career start for the Badgers. Clay has the tools to become a superstar, but he didn't claim the starting job in preseason camp and has struggled with his weight in the past. He comes off a very impressive performance against Fresno State and might establish himself as Wisconsin's top back with a strong showing against Wofford.
