National signing day is in the books, and it's time to evaluate the Big Ten teams and their classes. Although several potential Big Ten recruits are announcing their plans after signing day, most of the classes are complete.
Here's how ESPN Recruiting graded the Big Ten classes.
Let's take a look at how teams filled their big recruiting needs:
The Illini have had a nice run at defensive tackle with 2011 NFL first-round draft pick Corey Liuget and Akeem Spence, who enters 2012 as a legitimate pro prospect. They solidified the interior line for the future with recruits like Teko Powell and Vontrell Williams.
It's no secret Indiana needs to make significant upgrades on defense, and coach Kevin Wilson looked to the junior college ranks for help. Indiana added six juco defenders, including cornerback Tregg Waters and linebacker Jacarri Alexander. These players give the Hoosiers a chance to get better in a hurry.
Running back has again become a pressing need for Iowa with the departures of Marcus Coker and Mika'il McCall. While Iowa has lost running backs at an alarming rate, it also has developed young backs very well in recent years. The coaches hope to work their magic with Greg Garmon, who could be the most significant recruit of the 2012 class.
Arguably no staff in the country makes defensive line a bigger priority than Michigan, which has three coaches, including head man Brady Hoke, focused on the front four. The Wolverines lose standouts Mike Martin and Ryan Van Bergen from the 2011 line, but they addressed the situation in recruiting with pickups like defensive tackle Ondre Pipkins and defensive end Chris Wormley.
Michigan State is creating a nice recruiting pipeline at the wide receiver position. The Spartans lose their top two wideouts from 2011 (B.J. Cunningham and Keshawn Martin) but added several nice receiver pickups in the 2012, including Tennessee transfer DeAnthony Arnett and four-star prospects Monty Madaris and Aaron Burbridge.
Quarterback MarQueis Gray returns, and Minnesota needed to get him some help in the passing game after the departure of Da'Jon McKnight. The Gophers added some excellent pickups at the wide receiver position in Andre McDonald and Jamel Harbison.
The Huskers were thin at linebacker in 2011 and lose standout Lavonte David to graduation. Nebraska coaches also have discussed the need to add more traditional linebackers to face Big Ten offenses. Big Red filled the need in the 2012 recruiting classes with players such as Michael Rose and Jared Afalava.
Defense has been Northwestern's downfall in the past two years, and the Wildcats need more difference-makers on that side of the ball. They likely landed one in end/linebacker Ifeadi Odenigbo, an ESPNU 150 prospect who is Northwestern's most decorated defensive recruit in recent memory. Odenigbo could help immediately as a situational pass-rusher.
No Big Ten team made a bigger impact at one position than Ohio State did along the defensive line. The Buckeyes, who were a bit thin up front in 2011, got a lot better with this class, which is headlined by ESPNU 150 prospects Noah Spence, Adolphus Washington, Se'Von Pittman and Tommy Schutt.
Skyler Mornhinweg's decommitment stings a bit, as Penn State needs more quarterbacks in the mix, but the Nittany Lions also need more difference-makers at wide receiver and tight end. They helped themselves in the 2012 class with wide receiver Eugene Lewis, ranked as the nation's No. 34 wideout by ESPN Recruiting. Tight end Jesse James is another nice pickup.
Offensive line has been a position of stability for Purdue the past few seasons, but the Boilers lose two starters from the 2011 squad (Dennis Kelly, Nick Mondek) and will say goodbye to several more after 2012. Purdue had to reload up front, and the two highest-rated players in the 2012 class, according to ESPN Recruiting -- Jordan Roos and Cameron Cermin -- all play offensive line.
Quarterback is undoubtedly Wisconsin's top priority as Russell Wilson departs and Jon Budmayr and Curt Phillips battle back from major injuries. The Badgers needed a signal-caller in a small class and landed a decorated one in Bart Houston, a four-star prospect from California powerhouse De La Salle High School.
