It's time to look inside five Big Ten teams.
Penn State -- Despite Navorro Bowman's emergence, there has been some concern about linebacker play this year, and the picture only got cloudier last Saturday. After Michigan's run game started strong, the Nittany Lions called for reinforcements and put freshman Michael Mauti and sophomore Bani Gbadyu in the game. The two young players stepped up, combining for 10 tackles, 2.5 tackles for loss and a forced fumble. Both Mauti and Gbadyu could once again see increased playing time in place of Tyrell Sales and possibly Josh Hull against No. 9 Ohio State (ABC, 8 p.m. ET). Mauti's speed on the edge should help against Buckeyes quarterback Terrelle Pryor.
Wisconsin -- A week after saying the 2009 season had no impact on his starting quarterback decision, Badgers head coach Bret Bielema certainly appears to be looking toward the future at that position. Junior quarterback Dustin Sherer will make his second consecutive start Saturday against Illinois, and sophomore Scott Tolzien will take more snaps this week in practice with the second-team offense. Fifth-year senior Allan Evridge, who started Wisconsin's first six games, has effectively been moved to third string. Sherer and Tolzien will compete for the starting job next season with Curt Phillips and James Stallons.
Illinois -- Freshman offensive tackle Corey Lewis could see increased playing time against Wisconsin after performing well in his debut against Indiana. Lewis can play either tackle spot and spelled left tackle Xavier Fulton for several series last week. Sophomore Ryan Palmer will remain sidelined for some time with a foot stress fracture, and Lewis likely will be needed against the Badgers. Lewis also can play on the defensive line. "I wanted to get Corey in there," head coach Ron Zook said. "We kind of joked about that when we told him we were going to play him because he's 18 now and old enough. He's excited about it and I noticed a little different intensity out of him."
Purdue -- Head coach Joe Tiller admitted this week that Purdue's offense has become too basic and needs to diversify after four straight losses. In previous years, the Boilermakers entered every game with two "deceptives" in the offensive plan. This season, the outside-the-box, high-risk, high-reward plays have not been included. That will change Saturday against Minnesota (ESPN Classic, noon ET). "From this point forward I want to see, when the game plan is presented later in the week, two deceptives," Tiller said. "Now, I'm not guaranteeing you they're going to get called, but we're going to have 'em as a possibility anyway, which we haven't had." Purdue ranks ninth in the league in scoring offense (22.3 ppg).
Michigan -- Despite a third consecutive loss, the Wolverines might have found their featured running back last Saturday at Penn State. Junior Brandon Minor had 117 rush yards and two touchdowns against the Big Ten's No. 2 rush defense (103.9 ypg). Minor's emergence allows head coach Rich Rodriguez to take pressure off of true freshman Sam McGuffie and, to a lesser extent, true freshman Michael Shaw. McGuffie has carried the load for much of the season but needs more time to grow into a top role. Minor's ability to run inside and grind out yards will benefit Michigan down the stretch. The junior claimed the top spot on this week's depth chart.
