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.
