Ten items to track around Big Ten football in Week 2:
1. House party: If the second night game at Michigan Stadium is anything like the first, we'll all be thrilled (well, except for those Notre Dame folks). Michigan and Notre Dame delivered the drama two years ago under the lights, and the spectacle Saturday night in Ann Arbor should once again be incredible. The teams' past four meetings have all been decided by seven points or fewer (19 points total). The series sadly disappears after the 2014 meeting in South Bend, so enjoy it while it lasts.
2. Rees vs. Gardner: Notre Dame-Michigan features another appetizing quarterback matchup. While Tommy Rees remains a polarizing figure for some Notre Dame fans, it's hard to argue with what he has done against Michigan. Before last Saturday's opener against Temple, Rees' only 300-yard passing performance came against Michigan two years ago, and he led Notre Dame to victory last fall. Rees can stretch the field, as he had more passes of 20 yards or longer against Temple (7) than Everett Golson had in any game last season. Devin Gardner was Michigan's leading receiver last year against Notre Dame, but he's firmly entrenched as a quarterback. Gardner has been deadly in the red zone for the Wolverines, converting 19 touchdowns in 22 red zone trips as the starter.
3. Spartans looking for a spark: Michigan State basically has two more weeks to get its offense right before facing one of the nation's top defenses on the road at Notre Dame. The unit's opening act was highly disappointing, as Michigan State averaged just 3.8 yards per play against a Western Michigan defense that ranked 61st nationally in 2012. Head coach Mark Dantonio has kept mostly quiet about his quarterback situation this week as four players continue to get reps in practice. The Spartans need a solution there and at other offensive spots against South Florida, which allowed 56 points to McNeese State in its opening loss.
4. Illini aim to continue big-play ways: One of the nation's most feeble offenses in 2012 broke out last week against Southern Illinois, as Illinois recorded six plays of 30 yards or longer -- matching its total from all of last season! Senior quarterback Nathan Scheelhaase recorded a career-high 416 pass yards and featured weapons like Josh Ferguson and Ryan Lankford. The question is whether the Illini can come close to that type of production against a much, much tougher opponent in Cincinnati, which held Purdue to one short scoring drive and only 226 yards last week. We'll get a much better gauge about Illinois' offensive progress against Tommy Tuberville's defense.
5. Northwestern's health: After a mostly injury-free season in 2012, Northwestern already has been bitten by that pesky bug early this fall. The Wildcats will be without starting cornerback Daniel Jones (knee) for the rest of the season, putting redshirt freshman Dwight White in the spotlight against Syracuse. Top quarterback Kain Colter (head) and running back Venric Mark (leg) both are questionable for the game. If Northwestern can survive again like it did last week against Cal, it has a chance to get healthy in the next two weeks against weaker opponents before a two-week prep for Ohio State.
6. Roby watch in Columbus: After playing nine new defensive starters in last week's opener against Buffalo, Ohio State regains a very big piece in All-Big Ten cornerback Bradley Roby, who returns from suspension. Coach Urban Meyer wanted Roby to re-prove himself as a starter this week in practice, but it's only a matter of time before the junior distinguishes himself. Ohio State is looking for a cleaner performance in all three phases against struggling San Diego State, and it will be interesting to see how Roby performs.
7. Indiana's offensive efficiency: Kevin Wilson's Hoosiers scored touchdowns on five of their first six offensive possessions in last week's opener against Indiana State, en route to a Memorial Stadium-record 73 points. If Indiana can come close to that type of efficiency Saturday against Navy, it will improve to 2-0. Possessions likely will be limited against the Midshipmen, as Indiana found out last year when it had only 10 offensive drives in a 31-30 loss. The Hoosiers had to settle for three field goals of 30 yards or less and need to be better about punching it in against Navy. "You don't get as many at-bats," Wilson said.
8. Second chances: Purdue and Iowa didn't get off to the starts they wanted in Week 1, and neither did Nebraska's defense, which surrendered 35 first downs and 602 yards to Wyoming in the opener. Fortunately, all three teams should redeem themselves against weaker competition on Saturday. The Boilermakers need to boost quarterback Rob Henry's confidence and fix their communication problems on offense against Indiana State. Iowa quarterback Jake Rudock must rebound from his late interception against Missouri State. The Huskers defense, meanwhile, aims to clean things up against a Southern Miss team that has lost 13 straight and scored just 15 points against Texas State last week.
9. Wolverines' youth put to test: Don't be surprised if Michigan-Notre Dame comes down to how well the Wolverines' young interior offensive line performs against an elite Fighting Irish defensive front led by nose guard Louis Nix III and end Stephon Tuitt, two potential first-round picks in next April's NFL draft. Michigan will start redshirt freshman Kyle Kalis at right guard, true sophomore Jack Miller at center and redshirt sophomore Graham Glasgow at left guard. They'll be challenged all night long (especially Miller) as they try to create running room for Fitzgerald Toussaint and protect Gardner.
10. Hack's home debut: Penn State fans have been waiting more than a year and a half to watch quarterback Christian Hackenberg take snaps at Beaver Stadium. They'll finally get their chance Saturday as the Lions face Eastern Michigan in their home opener. Hackenberg had a few expected hiccups in his collegiate debut against Syracuse but also showed why he can be such a special player for Penn State's offense. Head coach Bill O'Brien vows to put Hackenberg in better positions to succeed this week. Hackenberg also will have top weapon Allen Robinson at his disposal from the start, which should make a big difference.
