There are some positions on the depth chart that make Big Ten coaches cringe. There are other spots that make them smile and nod their heads.
Let's take a look at several fully loaded positions in the Big Ten.
Ohio State's defensive line: There is talk the Buckeyes' front four could be the best since the 2002 national championship squad. Ohio State is stacked at defensive end with All-Big Ten candidate Thaddeus Gibson, Cameron Heyward and Lawrence Wilson, who can be effective if healthy. Tackle Doug Worthington brings a ton of experience to the interior line, and Dexter Larimore and Todd Denlinger add depth there.
Iowa's offensive line: This group is well on its way to restoring the tradition established during the early part of coach Kirk Ferentz's tenure. Iowa boasts the league's top tackles tandem in Bryan Bulaga and Kyle Calloway, and there are a host of experienced interior linemen. Julian Vandervelde developed nicely in 2008, and Andy Kuempel, Rafael Eubanks and Dan Doering all are solid options at guard. The emergence of oft-injured Dace Richardson this spring adds another body to the mix. Aside from the center spot, Iowa looks extremely solid up front.
Michigan State's secondary: Despite losing All-Big Ten safety Otis Wiley, Michigan State should be even stronger in the back half. Three starters return in the secondary, including corners Chris L. Rucker and Ross Weaver. Michigan State boasts depth with corners Jeremy Ware and Johnny Adams and safeties Kendell Davis-Clark and Marcus Hyde. And the breakout performance of the spring came from another safety, Trenton Robinson, who certainly will see playing time this season.
Penn State's linebackers: Linebacker U. is back in 2009. Penn State boasts one of the nation's top linebacker tandems in Sean Lee and Navorro Bowman, both of whom will contend for All-America honors. And it doesn't stop there, as sophomore Michael Mauti is poised for a big year on the outside. Penn State also boasts veteran depth with Josh Hull, Chris Colasanti and Bani Gbadyu.
Illinois' wide receivers: Juice Williams will have no shortage of options in the passing game this fall. All-America candidate Arrelious Benn leads the Big Ten's deepest receiving corps, which features Jeff Cumberland, Chris Duvalt, A.J. Jenkins, Cordale Scott and Jack Ramsey. Florida transfer Jarred Fayson worked his way into a starting spot this spring and will draw opposing defenders away from Benn.
Michigan's running backs: Whoever wins the starting quarterback job in Ann Arbor will have plenty of help in the backfield. Hopes are extremely high for senior Brandon Minor, who finished strong last season despite battling several injuries, including one to his right (ball-carrying) wrist. Backing up Minor will be Carlos Brown and Michael Shaw, both of whom will be more accustomed to Rich Rodriguez's offense. Bite-size back Vincent Smith emerged this spring to provide another option with breakaway speed.
Northwestern's secondary: One of the league's weakest units a few years ago has transformed into a major strength for the Wildcats. All four starters return from 2008, and safety Brad Phillips and cornerback Sherrick McManis are strong candidates for All-Big Ten honors. Safety Brendan Smith and cornerback Jordan Mabin both are natural playmakers, and Northwestern boasts depth in players like Brian Peters, Justan Vaughn and David Arnold.
Wisconsin's H-backs/tight ends: Travis Beckum's star-crossed senior season opened opportunities for other players in 2008, and the result is a multitude of options at tight end for 2009. Mackey Award candidate Garrett Graham leads the way at the H-back spot, and senior Mickey Turner and junior Lance Kendricks provide reliable options in the passing game.
