National Signing Day is right around the corner, and Big Ten teams will look to add depth and identify a few immediate contributors in the upcoming recruiting classes. What do these squads need the most?
Here's a look:
Offensive line: The line hasn't been great the last two seasons, and Illinois loses standout Jon Asamoah and center Eric Block. Illinois looks strong at running back in 2010, but someone needs to create rushing lanes.
Safety: The Illini defense hasn't been the same since the departures of safeties Kevin Mitchell and Justin Harrison following the 2007 season. Ron Zook could really use a safety or two who could step in and contribute right away against the run and in coverage.
Defensive end: The Hoosiers lose two multiyear starters at end: Jammie Kirlew, a two-time All-Big Ten selection, and Greg Middleton, who led the nation in sacks in 2007. Indiana's pass rush will suffer unless it builds depth at end and throughout the line.
Secondary: Indiana loses starting safeties Austin Thomas and Nick Polk as well as its top cornerback, Ray Fisher. Expect the Hoosiers to go very heavy with defensive back recruits as they try to shore up an area that has been problematic during the last decade.
Offensive line: The situation on the line certainly is better than it was a year ago, but the departure of talented left tackle Rodger Saffold creates a void. Indiana is the type of team that always could use more depth up front so the drop-off between starters and backups isn't so dramatic.
Offensive line: Iowa loses four linemen who started most or all of its games last year, including All-Big Ten performers Bryan Bulaga and Dace Richardson. The Hawkeyes can't expect freshmen to come in and start right away up front, but they need some insurance if injuries crop up.
Linebacker: Standouts Pat Angerer and A.J. Edds depart, and while Iowa has some guys ready to step in, it can always use depth in the defensive midsection. The Hawkeyes defensive line should sizzle in 2010, but they need sure tacklers at linebacker, too.
Secondary: There's no mystery here, as the Wolverines really struggled with breakdowns in the back four and lose standout cornerback Donovan Warren to the NFL draft. Michigan needs to bolster its talent level at both cornerback and safety to have improved results in 2010.
Linebacker: The Wolverines linebackers struggled in 2009, and there are opportunities for young players to step in here and contribute. Obi Ezeh and Jonas Mouton are back, but it's obvious this is another area Michigan must upgrade this coming season.
Specialists: Michigan loses both of its starting specialists, including All-Big Ten punter Zoltan Mesko, a Ray Guy Award finalist. This is always an area where a strong true freshman can step in and contribute immediately.
Trenches: Line play was a weakness for the Spartans in 2009, and they'll be looking to upgrade on both sides of the ball. They lose top pass rusher Trevor Anderson as well as left tackle Rocco Cironi, center Joel Nitchman and guard Brendon Moss on the offensive line.
Secondary: This unit turned out to be a major disappointment, considering the preseason expectations. Michigan State loses safety Danny Fortener and corners Ross Weaver and Jeremy Ware, and there should be ample opportunities for freshmen to step in and play.
Linebacker: Probably not a critical need, but Michigan State needs to start preparing for life after Greg Jones. The Spartans also lose Adam Decker and Brandon Denson from the 2009 team, and Eric Gordon will depart with Jones after 2010.
Cornerback: The Gophers lose both of their starters, Traye Simmons and Marcus Sherels, and will be looking to build depth behind Michael Carter in 2010. I'm very excited about what Minnesota returns at safety, but the situation at corner seems a bit unsettled.
Offensive line: Minnesota will stick with the pro-style offense no matter who becomes its next coordinator, but for the system to truly click, the Gophers really need to upgrade their line. The team returns quite a few linemen for 2010, but it'll look for improved depth up front.
Running back: After finishing last in the Big Ten in rushing each of the last two seasons, Minnesota certainly will look to get better here. Kevin Whaley's departure creates a spot for a newcomer to compete with Duane Bennett and DeLeon Eskridge for carries.
Secondary: The Wildcats lose three multiyear starters in the secondary, including All-Big Ten honorees Sherrick McManis and Brad Phillips. They'll need to build depth around safety Brian Peters and corner Jordan Mabin to avoid a major drop-off.
Defensive line: Corey Wootton's departure leaves NU without a proven pass rusher who can command double teams. The Wildcats also will look to build depth at defensive tackle after losing Adam Hahn and Marshall Thomas.
Safety: This is one of few spots where Ohio State loses two long-time contributors in Kurt Coleman, a first-team All-Big Ten selection, and Anderson Russell. Though Jermale Hines played a lot in 2009, the Buckeyes want to build depth around him.
Wide receiver: If the Buckeyes' offense builds off of its Rose Bowl performance, the wideouts figure to be more involved. Ohio State should be fine for 2010 with DeVier Posey and Dane Sanzenbacher, but it could lose both after the season and needs to start grooming replacements. These recruits also could help the return game, where Ohio State loses Ray Small and Lamaar Thomas.
Quarterback: Two-year starter Daryll Clark is gone and Pat Devlin transferred following the 2008 season, creating a wide open competition at quarterback heading into 2010. Kevin Newsome and Matt McGloin will compete, but Penn State always wants others in the mix there.
Linebacker: Penn State rarely has trouble reloading here, but it loses all three starters, including back-to-back first-team All-Big Ten selection Navorro Bowman. The Lions will look to build depth and identify an early contributor or two for the 2010 season.
Tight end/wideout: The Lions lose both Andrew Quarless and Mickey Shuler, so expect them to add a tight end or two in the incoming class. Quarless was a major part of the passing attack and Shuler hauled in two touchdowns, so Penn State won't neglect this position.
Secondary: A no-brainer here, as Purdue loses all four starters in the secondary, which has ranked in the upper half of the league against the pass. The Boilers likely need a newcomer or two to contribute right away in 2010.
Linebacker: Jason Werner hopes to return for a sixth year, but Purdue can't take any chances with a position that has struggled a bit the last two seasons. Danny Hope likes his young linebackers (Antwon Higgs, Dwayne Beckford), but he's looking for more.
Wide receiver/tight end: Purdue can never have enough pass receivers, and Hope will look to build around All-Big Ten performer Keith Smith in 2010. The Boilers lose No. 2 wideout Aaron Valentin, and Smith and tight end Kyle Adams depart after 2010.
Defensive line: All-Big Ten defensive end O'Brien Schofield departs, and the Badgers will be pretty young up front in 2010. It's important that Wisconsin builds depth behind players like J.J. Watt and Jordan Kohout.
Tight end: Lance Kendricks certainly eased concerns about this spot in the Champs Sports Bowl, but Wisconsin still loses All-Big Ten selection Garrett Graham as well as reserve Mickey Turner. No team in the Big Ten features the tight end spot as much as Wisconsin, so it'll be important to find a few recruits.
