NCF Nation: Perry Dorrestein
2. Ohio State: The talent always has been there, and the physical play finally showed up late last fall. Ohio State's line finished 2009 on a very strong note and returns pretty much everyone for 2010. First-team All-Big Ten guard Justin Boren leads the group along with fellow guard Bryant Browning. Center Michael Brewster enters his third season as a starter, and right tackle J.B. Shugarts came along last year. If gifted left tackle Mike Adams effectively protects Terrelle Pryor's blind side, the Buckeyes will be extremely tough to stop.
3. Michigan: The Wolverines boast one of the Big Ten's best interior line tandems in guard Stephen Schilling and center David Molk, who returns from an ACL injury. When Molk was healthy in 2009, Michigan consistently moved the football. His return is a major boost. The Wolverines need to solidify the tackle spots but have experienced options in Perry Dorrestein and Mark Huyge. Michigan's offensive line recruiting also should pay off as redshirt freshmen like Taylor Lewan solidify the depth.
4. Penn State: The line had an average performance in 2009 and struggled against elite defensive fronts, but things should improve this fall. Stefen Wisniewski, who moves back to guard from center, is one of the nation's most experienced and polished offensive linemen. He leads a group that also features veterans Lou Eliades and Johnnie Troutman. Penn State needs big things from new starting left tackle Quinn Barham.
5. Northwestern: All five starters return from 2009, but there's competition at three spots in camp. I see this as a testament to Northwestern's strong O-line recruiting the past four seasons. While experience is great, the Wildcats need to be more physical in run blocking and could benefit from some new faces (or some old ones hardened by competition). Left tackle Al Netter and center Ben Burkett are All-Big Ten candidates, and watch out for Patrick Ward, a heralded 2009 recruit who steps into the spotlight at right tackle this season.

It's time to go inside five Big Ten teams as they prepare for the start of league play on Saturday.
Illinois -- The defensive line might finally be taking shape for the Illini after some illness/injury issues. Sophomore Josh Brent is back in the fold at defensive tackle, which has allowed standout Will Davis to move back to his natural position of defensive end. Freshman Cory Liuget also has emerged at defensive tackle, a spot vacated when projected starterSirod Williams tore his ACL during training camp. "It's important that we can [rotate] guys in there and keep us fresh," head coach Ron Zook said. Zook called the defensive line the team's strength before the season, but the group will need to elevate its play Saturday night against Penn State's powerful rushing attack, which ranks eighth nationally (274.3 ypg).
Indiana -- When the NCAA cleared Florida transfer Jerimy Finch to play this season, Indiana's secondary looked like one of the deepest groups on the team. That depth will be tested Saturday against Michigan State (ESPN, noon ET). The Hoosiers will be without at least one starting safety (Nick Polk, knee) and could miss their other starter, as strong safety Austin Thomas is questionable for the game with a lower leg injury. Coach Bill Lynch announced that starting cornerback Chris Phillips will miss the remainder of the season with a torn ACL. So the Hoosiers could be replacing three starters against the Spartans. Finch figures to see plenty of time.
Michigan -- A bye week allowed Michigan's offensive line time to heal, though a knee injury to tackle Perry Dorrestein last week in practice clouded things a bit. Mark Ortmann is expected back from a dislocated elbow and should rotate at left tackle with Dorrestein if Dorrestein can play. Left tackle is one of three offensive line spots that have an "OR" listed between potential starters on the depth chart. Converted defensive linemanJohn Ferrara could start at right guard in place of David Moosman, who is listed at both guard and center on the depth chart. Redshirt freshman Mark Huyge also should be back from an ankle injury, so the coaches have some decisions to make up front.
Minnesota -- True freshman running back DeLeon Eskridge has stepped up in the two games after Duane Bennett's knee injury, but coach Tim Brewster isn't quite ready to call Eskridge his featured back. Brewster said Eskridge, freshman Shady Salamon and junior Jay Thomas all will play Saturday at No. 14 Ohio State, and Minnesota will stick with whoever has the hot hand. The coach admitted that identifying a clear-cut starter has become less of a concern than it was after Bennett went down. Eskridge has 192 rushing yards and five touchdowns the last two games.
Ohio State -- Quarterback isn't the only offensive position where youth will be served Saturday against Minnesota. Freshman Michael Brewster remains the starter at center on this week's depth chart after playing a prominent role last week against Troy. The Buckeyes movedJim Cordle from center to left guard after Steve Rehring injured his foot against USC. Rehring will miss "another week or so," coach Jim Tressel said, so that means more time for Brewster, one of several heralded freshmen in Ohio State's recruiting class.

Injuries are cropping up around the league, and coaches are shuffling pieces to try to find the right fit. Here's a look at five key issues in the Big Ten.
Minnesota -- Just when the Golden Gophers found a viable running threat, they received news that Duane Bennett tore his ACL against Bowling Green and will miss the rest of the season. Coach Tim Brewster will audition three players -- junior Jay Thomas and freshmen Shady Salamon and DeLeon Eskridge -- at the running back spot in hopes of identifying a featured back. The Gophers need more than one capable runner, but Brewster doesn't want a rotation there. Though Thomas has by far the most experience, Eskridge and Salamon are listed behind Bennett on this week's depth chart.
Michigan State -- The Spartans apparently no longer have cornerbacks or safeties, just general defensive backs. Before the season, coach Mark Dantonio moved starting corner Kendell Davis-Clark to safety after projected starter Roderick Jenrette took a leave of absence. Dantonio now is considering switching another starting cornerback, Ross Weaver, to safety after Davis-Clark sustained a shoulder injury against Cal and missed last week's matchup against Eastern Michigan. Davis-Clark is listed as day-to-day but didn't appear on this week's depth chart for Florida Atlantic.
Ohio State -- Cornerback Donald Washington returns from a two-game suspension Saturday against USC (ABC, 8 p.m. ET), but the two-year starter might not retain his job. Ohio State likely will platoon Washington and sophomore Chimdi Chekwa, who has started the first two games. Coach Jim Tressel also seems intent on keeping Jermale Hines in the mix, possibly at nickel back. Hines should get decent playing time Saturday because the Buckeyes don't know whether linebacker/safety Tyler Moeller will be able to play after suffering an injury.
Michigan -- Redshirt sophomore Perry Dorrestein likely will make his season debut as the Wolverines' starting left tackle Saturday at Notre Dame after Mark Ortmann dislocated his elbow last week. Dorrestein previously had backed up Stephen Schilling at left tackle. Michigan already is without two guards who went down with injuries before the season. Coach Rich Rodriguez expects Bryant Nowicki and true freshman Patrick Omameh to fill in behind Dorrestein on the left flank.
Penn State -- The still-unresolved suspensions of starting defensive linemen Maurice Evans and Abe Koroma and the season-ending injury to Jerome Hayes leave the Nittany Lions in a bit of a bind. Both the end and tackle positions have depth issues, and end might be a greater concern as Penn State doesn't have much behind Josh Gaines and Aaron Maybin. One possibility would be moving true freshman Jack Crawford from tackle to end, though Paterno is leery about Crawford's inexperience. If Crawford switches, it puts more pressure on keeping Jared Odrick, Ollie Ogbu and Tom McEowen healthy.
