The NASDAQ and the Nikkei got nothing on this market.
Penn State's Killer Zs: Zach Zwinak was no better than the fifth-string tailback for the Nittany Lions this summer. But in the last two games, the 230-pound sophomore has rushed for 94 yards against Temple and an even 100 versus Illinois. "He's got good speed, but he's not a scat back," head coach Bill O'Brien said. "He's a physical, downhill guy that likes to press the line of scrimmage." Penn State's second-leading rusher is Michael Zordich, a senior whose 30 carries this year are just five shy of his previous career total. Don't sleep on these Zs.
Jordan Cotton: The Iowa receiver came to campus as a well-regarded in-state recruit but spent two years doing not much of anything after a redshirt season. Cotton is finally emerging, with four catches in the Hawkeyes' last two games, including a 47-yard touchdown grab on a flea flicker last week against Minnesota. Cotton is averaging 20.2 yards per catch this season.
Ohio State's offensive line: A maligned group most of the offseason and even early in the year, the Buckeyes' offensive front exerted its will last week at Michigan State. Ohio State ran for more than 200 yards against a Spartans defense that was leading the Big Ten and was among the best in the nation against the run. What's more, they closed out the 17-16 win by churning out yards and first downs in the final minutes when Michigan State knew the run was coming. Urban Meyer named his five starters the offensive MVP after the game. "Those five guys are locked and loaded," he said. "That's the group right now that I'm most pleased with."
Nate Sudfeld: The Indiana quarterback didn't arrive on campus until this summer but looks like he should be starting going into Week 6. Sudfeld replaced an injured Cameron Coffman against Ball State and led a rally that nearly won the game for the Hoosiers. Last week, after IU fell behind Northwestern 20-0 in the first half, Sudfeld came on right before halftime and gave the offense a spark, leading a comeback that ultimately came up short. Sudfeld is still competing in practice with Coffman for the starting job, but his needle is definitely pointing up.
Blackshirts' seniors: When Nebraska needed to make a defensive stand after falling 17 points down to Wisconsin last week, its seniors stepped up. Defensive tackle Baker Steinkuhler and linebackers Will Compton, Alonzo Whaley and Sean Fisher combined for eight tackles for loss and two sacks to stymie the Badgers and lead the comeback effort. Compton in particular had a terrific game. The Huskers veterans haven't always performed at an elite level, and they'll need to carry that Wisconsin effort over to this weekend and beyond in order to win the Big Ten.
Minnesota's safeties: Jerry Kill said one big reason his team couldn't stop the Iowa running game last week is that his safeties missed too many tackles in run support. Even Derrick Wells, who's had a fantastic season, turned in a poor performance, Kill said. The Gophers will spend much of the bye week working on improving that with their safeties, and getting Brock Vereen back fully healthy should help.
Michigan's road production: As Kyle Meinke writes, the Wolverines are averaging 20.9 points per game on the road the past two seasons, compared with more than 40 at home. This year, Michigan has scored just 20 total points in its two games away from Ann Arbor (albeit against outstanding defenses in Alabama and Notre Dame). Denard Robinson's numbers are much worse away from the Big House as well. It's an issue the team must resolve before going to Purdue this week
Ex-Iowa running backs: The grass isn't always greener, even if it's FieldTurf. As Mike Hlas points out, former Hawkeyes running backs Marcus Coker and Mika'il McCall aren't exactly flourishing after leaving Iowa City. Coker is the second-leading rusher on his team at FCS Stony Brook and ranks 66th in the division in rushing yards. McCall has 8 fewer yards than Coker at Southern Illinois. Neither of them have come close to walk-on Mark Weisman's 507 yards, which he's accomplished in a mere three games. So maybe it's not the player, but the system.
Peace, love and understanding between Spartans, Buckeyes: Mark Dantonio wasn't the biggest fan of Urban Meyer during recruiting season last winter. Ohio State defensive tackle Johnathan Hankins said before last week's game that he would try to rip Michigan State running back Le'Veon Bell's head off. Hankins nearly had his eyes gouged out by the Spartans in a scrum. And defensive coordinator Pat Narduzzi complained that the Buckeyes didn't send over the proper game film. Can't we all just get along?
Illinois' offense: Weren't the Illini supposed to be more explosive with Tim Beckman's spread attack? The team ranks 97th in the country in scoring at just 22.6 points per game and 96th in total offense. And those totals include a stat-padding 44-0 win over a truly awful FCS opponent (Charleston Southern). Not much has gone right for Illinois this year, but if the program wants to start building interest among its fans, scoring some points would be a nice way to start.
