2. Coaching debuts: Purdue's Darrell Hazell and Wisconsin's Gary Andersen both have enjoyed honeymoon periods at their respective schools, but they both know the mood can change once the games begin. Hazell faces an uphill climb as Purdue plays the Big Ten's toughest schedule, beginning Saturday on the road against a Cincinnati team that won 10 games last season. Andersen embarks on the unique challenge of blending his philosophy with a veteran team that has won the past three Big Ten championships. Wisconsin will have no trouble with Massachusetts, but keep an eye on how the Badgers' new 3-4 defense performs.
Iowa again starts the season facing Northern Illinois and QB Jordan Lynch.
3. Pivotal game at Kinnick: Iowa's victory in the 2012 opener against a Northern Illinois team that went on to the Orange Bowl proved to be one of few highlights in a highly disappointing season. The Hawkeyes once again kick things off against an NIU squad led by Heisman Trophy candidate Jordan Lynch, who wants to avenge last year's setback. It's hard to call a season opener a must-win, but Iowa needs to generate some positive momentum early before a very challenging Big Ten schedule.
4. Speed trap in Berkeley: Still glowing from a 10-win season in 2012, Northwestern faces several unique challenges in its opener Saturday night at Cal. The Wildcats must contain the "Bear Raid" offense orchestrated by new Cal coach Sonny Dykes. The Bears are a mystery team with a ton of youth led by a freshman quarterback (Jared Goff). Northwestern also must contend with a late kickoff and moved its practices this week from the afternoon to the evening. The Wildcats are even taking naps to prepare.
5. Dontre's inferno: Aside from Christian Hackenberg, no Big Ten incoming freshman has generated more buzz in camp than Ohio State's multipurpose speedster Dontre Wilson. The onetime Oregon commit could be a transformative player for Urban Meyer's offense, filling the so-called Percy position at wide receiver/running back. Wilson should get some opportunities for explosive plays as Ohio State opens the season Saturday against Buffalo.
6. Juco hello: The Big Ten doesn't bring in as many junior college transfers as other leagues, but several juco arrivals could be impact players this season. Nebraska fans are anxious to see if Randy Gregory can be the pass -rushing force they've been waiting for. Wisconsin's Tanner McEvoy fell out of the mix at quarterback but will see time at other positions like wide receiver. Illinois wide receiver Martize Barr provides a much-needed weapon in the pass game for Nathan Scheelhaase. Minnesota linebackers Damien Wilson and De'Vondre Campbell could solidify the defensive midsection. It'll also be interesting whether quarterback Tyler Ferguson logs some field time for Penn State.
7. Oh, Henry: Purdue senior Rob Henry will make his first start at quarterback since the 2010 season (yes, you read that right) on Saturday against Cincinnati. An ACL injury sustained in late August prevented Henry from starting in 2011, and the versatile Boiler wore several hats for the offense in 2012. After beating out Danny Etling and Austin Appleby in camp, Henry guides coordinator John Shoop's pro-style offense into Nippert Stadium, where Purdue aims for a win that would provide "instant gratification," according to Hazell.
8. To the Max: Senior Andrew Maxwell emerged from Michigan State's quarterback morass to claim the starting job, at least for now. But after struggling for much of his first season as the starter, Maxwell needs a strong start Friday night against Western Michigan. Head coach Mark Dantonio is committed to playing multiple quarterbacks early in the season, so Connor Cook should see time against the Broncos. Maxwell must prove he's the top option by showing better command and rhythm with his oft-criticized receiving corps.
9. Let's be Frank: Few Michigan players not named Devin Gardner have generated more positive ink in the offseason than defensive end Frank Clark. The 6-foot-2, 273-pound junior had a strong finish to the 2012 season and could be the pass-rusher Michigan needs to turn a corner defensively this fall. Then again, we've seen certain Michigan defenders hyped up (cough, Will Campbell, cough) and never do much. It'll be interesting to see if Clark sets the tone for a big year Saturday against Central Michigan.
10. APB for playmakers: Other than Penn State and Iowa, the Big Ten actually returns a decent amount of experience at quarterback for the 2013 season. But the league lacks offensive playmakers, especially at wide receiver. Teams like Ohio State, Minnesota, Michigan State and Illinois are hoping to surround their quarterbacks with more options. It will be interesting to see who establishes himself in Week 1 as a go-to option.
