It's time to go inside five Big Ten teams preparing for the second round of league games.
Illinois: Head coach Ron Zook will increase his rotation on defense after the Illini dropped to last place in the Big Ten in points allowed (32 ppg). LinebackersRussell Ellington and Sam Carson and safety Donsay Hardeman all are expected to see more plays Saturday at Michigan (ABC, 3:30 p.m. ET). Zook has some versatility with Travon Bellamy , who can play both safety and cornerback. The coach attributed Illinois' run-stopping struggles (182.5 ypg allowed) to the back half as the team tries to overcome the losses of All-American middle linebacker J Leman and talented safetiesKevin Mitchell and Justin Harrison. "I don't foresee starting lineup changes," Zook said, "but I do see guys that are going to be held accountable. ... We're going to play more guys and our job is to make sure we fix it."
Michigan State: Defensive back Kendell Davis-Clark could be back soon after missing the last four games with a shoulder injury. Davis-Clark's return presents some interesting decisions for head coach Mark Dantonio, who originally shifted Davis-Clark from cornerback to safety afterRoderick Jenrette was asked to take a leave of absence from the team. Danny Fortener replaced Davis-Clark in the season opener at Cal and has performed well, ranking second on the team in tackles (29) with three pass break-ups and an interception. Davis-Clark, who started 11 games at cornerback last season, is listed behind Fortener on the depth chart for Saturday's game against Iowa (ESPN2, noon ET).
Minnesota: The Gophers continue to list three players as possible starters at running back on this week's depth chart, but head coach Tim Brewster acknowledged that freshman DeLeon Eskridge has taken the lead. Eskridge racked up a team-high 131 all-purpose yards in Minnesota's league-opening loss to Ohio State last week. With five touchdowns, he's already halfway to reaching Minnesota's freshman record of 10 set by Laurence Maroney in 2003. Another freshman, Shady Salamon, and junior Jay Thomas also remain in the mix for playing time. "If you had to say one of three guys stepped out, you'd say DeLeon Eskridge," Brewster said. "The other two guys will definitely continue to play some."
Ohio State: Aside from left tackle Alex Boone, none of the spots on Ohio State's offensive line are set in stone. True freshman Michael Brewster remains the starter at center, but Jim Cordle could move back over from guard if necessary. Cordle and a healthy Steve Rehring are listed as co-starters at left guard. Right tackle Bryant Browning also can play a guard spot, and Rehring is a possibility at tackle. Freshmen tackles J.B. Shugarts and Mike Adams also could be the mix at some point as much-needed competition increases up front.
Purdue: The Boilers' spread offense is at its best with a large rotation of receivers, and they're starting to see more playmakers emerge. Senior Desmond Tardy is listed as a starter on this week's depth chart ahead of junior Keith Smith after catching 10 passes for 175 yards and a touchdown last week against Notre Dame. Purdue also has seen encouraging moments from junior college transfer Aaron Valentin. Head coach Joe Tiller wants to see more from his other juco wideout, Arsenio Curry, who brings excellent size (6-foot-4, 217 pounds) but has yet to catch a pass. Tight end remains a question mark, as starter Kyle Adams is doubtful for Saturday's game against Penn State. Adams hasn't played since he hurt his knee on the opening kickoff of the season opener.
