Penn State Nittany Lions: Rashard Fant
Illinois: The secondary returns mostly intact from 2013, as Illinois returns starters at both cornerback spots (V'Angelo Bentley and Eaton Spence), as well as Zane Petty, who started the final seven games at free safety. Taylor Barton, who opened last season as a starting free safety, also is back. Building safety depth is important this spring as Illinois must replace Earnest Thomas III. Barton will compete with Jevaris Little and others for playing time. The depth is much better at corner as Darius Mosely and Jaylen Dunlap both saw significant action as freshmen last fall.
Indiana: Like Illinois, Indiana returns a lot in the defensive backfield but must improve after struggling to stop opponents in 2013. The Hoosiers also lose only one starter in safety Greg Heban, a mainstay during the past four seasons. There's a lot of experience at cornerback with returning starters Tim Bennett (senior) and Michael Hunter (junior), along with reserve Kenny Mullen (senior). Decorated recruit Rashard Fant, who redshirted in 2013, will compete for significant playing time. Senior safety Mark Murphy will lead the secondary, and sophomore Antonio Allen could fill the other safety spot when he returns from an ACL tear. Building depth here always is a priority at IU.
Iowa: The situation isn't as dramatic as the linebacker spot, but Iowa still must replace two productive players in cornerback B.J. Lowery and safety Tanner Miller, who combined for six interceptions in 2013. Lowery is the more significant loss, as he had 19 passes defended and three forced fumbles. The good news is Desmond King looks like a budding star and he will move into the featured role Lowery occupied. Jordan Lomax, Sean Draper and others will compete to start opposite King. Strong safety John Lowdermilk returns after a solid junior season. Lomax also could play free safety and will compete there with Anthony Gair and Nico Law, who both appeared in all 13 games last fall as reserves.
Maryland: The back four aims for better results on the injury front and on the field in 2013. Maryland returns both starters at safety in Sean Davis, the team's leading tackler with 102 last fall, and Anthony Nixon, but there should be competition behind them with A.J. Hendy and Zach Dancel. The cornerback position is worth watching this spring as Dexter McDougle departs and Jeremiah Johnson remains limited by a toe injury. Will Likely has opened the spring as a starter, and Alvin Hill could rise up after recording 24 tackles last season.
Michigan: The secondary took a step back in 2013 and all jobs are open even though Michigan returns two veteran cornerbacks -- Blake Countess and Raymon Taylor -- and some experience at safety. Jabrill Peppers, the nation's No. 2 overall recruit according to ESPN Recruiting Nation, will play a major role for the Wolverines this fall, whether it's at corner, safety or nickel. Junior Jarrod Wilson started the first seven games of last season at free safety, and Dymonte Thomas is a good candidate to start at one of the safety spots. Michigan should expect more from this group in 2014.
Michigan State: Will opposing offenses invade the No Fly Zone in 2014? Not if Michigan State can fill several spots, none bigger than Darqueze Dennard's at cornerback. Dennard, a unanimous All-American and the Jim Thorpe Award winner, departs to the NFL, and junior Trae Waynes slides into the featured corner role after a promising sophomore season. The competition opposite Waynes heats up this spring as Ezra Robinson, Darian Hicks, Jermaine Edmondson and Arjen Colquhoun compete. Free safety Kurtis Drummond boasts 21 career starts and enters 2014 as one of the league's top safeties. RJ Williamson likely will fill Isaiah Lewis' spot at strong safety, and Demetrious Cox provides depth.
Minnesota: Like the Gophers' defensive line, the secondary loses a huge piece in Brock Vereen, who played both safety and cornerback last season. But there might be enough returning pieces to fill the void. Cornerback Eric Murray had a very solid first season as a starter, and Minnesota also brings back Derrick Wells and Briean Boddy-Calhoun, both of whom have starting experience. Leading tackler Cedric Thompson and Antonio Johnson finished last season as the starting safeties, and both are back. Senior Grayson Levine provides some experience in a reserve safety role.
Nebraska: An important spring awaits new defensive backs coach Charlton Warren, who must identify new starters at cornerback, safety and nickel. The Huskers are replacing Ciante Evans and Stanley Jean-Baptiste, who combined for eight interceptions, 18 passes defended and 15 tackles for loss in 2013. Safety Andrew Green, who made 10 starts in 2013, also leaves. The good news is cornerback Josh Mitchell had an excellent bowl game and will fill a starting spot. Leading tackler Corey Cooper also returns at safety. There's not much experience at corner other than Mitchell, and Daniel Davie, Auburn transfer Jonathan Rose and others will compete. Nebraska brings back more at safety with Harvey Jackson, who made three starts in 2013, and junior Charles Jackson.
Northwestern: That the Wildcats' secondary could be one of the team's biggest strengths seemed laughable three years ago, but it could be true this fall. All four starters return, led by safety Ibraheim Campbell, one of the Big Ten's most productive defenders (262 career tackles). The depth at cornerback looks strong as starters Nick VanHoose and Matt Harris return, along with Dwight White and Daniel Jones, who opened 2013 as a starter and is coming back from an ACL tear. Traveon Henry should start alongside Campbell, and there are some promising young safeties like Godwin Igwebuike.
Ohio State: Pass defense proved to be Ohio State's downfall in 2013, and the Buckeyes' secondary will be under the microscope this spring as new assistant Chris Ash steps in. Ohio State loses All-Big Ten cornerback Bradley Roby and will lean more on Doran Grant, who started opposite Roby in 2013. Ash also expects big things from Tyvis Powell, who will start at one of the safety spots. Safety Vonn Bell finally logged significant playing time in the Orange Bowl and could become a permanent starter as a sophomore. Veteran Ron Tanner and Cam Burrows also are in the mix at safety. There should be good competition to start opposite Grant, as Armani Reeves tries to hold off redshirt freshmen Gareon Conley and Eli Apple.
Penn State: After a season of moving parts and inconsistent plays, Penn State hopes for a more settled secondary. Adrian Amos, who alternated between cornerback and safety last season, will lead the group and brings plenty of experience. Jordan Lucas likely will start opposite Amos at cornerback after making strides toward the end of his sophomore season. PSU loses some leadership at safety with Malcolm Willis and Stephen Obeng-Agyapong departing and will lean on Ryan Keiser and Jesse Della Valle, both of whom have starting experience. Converted wideouts Trevor Williams and Malik Golden provide depth at cornerback and safety, respectively.
Purdue: The rotation from 2013 returns almost completely intact, but Purdue loses a very big piece in cornerback Ricardo Allen, a four-year starter. Cornerback Frankie Williams enters his third year as a starter and will slide into Allen's featured role, while the competition for the other top corner spot will feature Antoine Lewis and Leroy Clark, among others. Purdue has plenty of experience at safety with Taylor Richards, who started every game in 2013, and Anthony Brown, who replaced the injured Landon Feichter and had 69 tackles. Feichter also is back from a broken leg.
Rutgers: This group is anxious to turn the page after a season filled with personnel issues and poor performance (Rutgers finished 120th nationally in pass defense). Senior safety Lorenzo Waters leads the group after recording 62 tackles and two forced fumbles in 2013. Johnathan Aiken will try to start opposite Waters at free safety, although he'll be pushed by Delon Stephenson and Tejay Johnson, who started three games last fall. Gareef Glashen started six games last season and seems likely to retain one of the top cornerback spots. There will be competition at the other between Anthony Cioffi and Nadir Barnwell, both of whom started games as true freshmen in 2013. The most intriguing player to watch is cornerback Ian Thomas, who returns to the team after quitting midway through last season, one that he began as a starter.
Wisconsin: The Badgers are relatively young at both secondary positions but boast far more experience at cornerback than safety. Junior Darius Hillary and sophomore Sojourn Shelton started all 13 games at cornerback last season. Peniel Jean adds even more experience at the position. Safety is much less settled as Dezmen Southward graduates, Michael Caputo shifts to linebacker and Tanner McEvoy returns to quarterback. Nate Hammon and Leo Musso both played in all 13 games last fall as reserves. Newcomers like Serge Trezy and Austin Hudson could compete for time when they arrive this summer.

As we put a bow on national signing day 2013, let's take a look at some superlatives ...
Biggest winner: Ohio State. The Buckeyes took a great class and made it even better with the additions of elite safety prospect Vonn Bell and four-star receiver prospect James Clark. They also held onto running back recruit Ezekiel Elliott. Plucking Bell out of SEC country made a significant statement, as Ohio State secured the nation's No. 3 class and the best in the Big Ten. Although other Big Ten programs secured strong classes -- Michigan, Nebraska, Penn State, Wisconsin, Michigan State -- Ohio State made the most headlines Wednesday.
Best closer: Ohio State co-defensive coordinator/safeties coach Everett Withers. Although Buckeyes head coach Urban Meyer is unquestionably one of the nation's top closers, Withers merits a mention here after steering Bell to sign with the Scarlet and Gray. "I've seen some really good efforts," Meyer said Wednesday. "Everett Withers from start to finish, his effort on Vonn Bell, as good as I've ever seen." Bell's high school coach called Withers the "most proficient and professional recruiter we've ever dealt with," according to The (Cleveland) Plain Dealer. Withers played a major role in Ohio State securing five defensive backs ranked in the top 50 by ESPN Recruiting.
Biggest surprise: Indiana and Penn State. The Hoosiers have reached only one bowl game since the 1993 season and boast just five wins the past two seasons, but things are looking up in Bloomington. Kevin Wilson and his staff signed what appears to be a very solid recruiting class, especially on the defensive side, where IU has struggled for years. The Hoosiers signed two four-star defensive linemen from within the state -- Darius Latham and David Kenney III -- and bolstered the secondary with Rashard Fant and others. Penn State overcame NCAA scholarship sanctions and a multiyear bowl ban to sign the nation's No. 24 class, headlined by quarterback Christian Hackenberg, rated by ESPN Recruiting as the nation's top pocket passer.
Who flipped/biggest loss: The only notable intra-league flip on signing day -- and it wasn't a major surprise -- saw linebacker Reggie Spearman, a one-time Illinois commit, signing with Iowa. Ohio State (Taivon Jacobs) and Wisconsin (Marcus Ball) lost commits to Maryland and Arizona State, respectively, while Minnesota made a late flip with junior college linebacker De'Vondre Campbell, who was expected to sign with Kansas State. But for the most part, Big Ten teams played good defense on signing day.

Bold prediction: Penn State will hang on to a top-25 class, even if just by the slimmest of margins. Bill O'Brien and his staff deserve all the credit in the world for having to originally put together a class after the scandal and then reshaping it after NCAA sanctions were levied in July.
Biggest need: The Illini's offense was arguably the worst in the Big Ten in 2012, and Illinois needs help just about everywhere on offense, especially at the skill positions.
Biggest recruit: Four-star athlete Aaron Bailey is the future at quarterback for Illinois, and the coaches will expect him to be ready to take the reins once Nathan Scheelhaase moves on.
Biggest need: To just put up a fence around Indianapolis and the state of Indiana. Kevin Wilson did that, assuaging defensive line concerns in the process by adding Indianapolis linemen David Kenney III and Darius Latham.
Biggest recruit: The Hoosiers are not accustomed to landing ESPN 150 prospects, but not only did they get Rashard Fant, but they got him all the way out of Georgia.
Biggest need: After having several productive running backs over the past decade, the Hawkeyes are hurting in the backfield due to injuries and off-the-field issues.
Biggest recruit: The Hawkeyes were after Berkley Edwards for a while, but once that fell through they put the screws to former Boston College running back commit LeShun Daniels. He flipped shortly after an official visit to Iowa.
Biggest need: Brady Hoke is transitioning to a pro-style offense, and he needed a pocket passer and a running back who makes his living in between the tackles.
Biggest recruit: ESPN 150 quarterback Shane Morris is that pro-style quarterback, but he is also the unquestioned leader of Team 134 and helped put together one of the nation’s top classes.
Biggest need: The Spartans will lose their top two rushers from 2012, including Big Ten rushing leader Le’Veon Bell, so running back is a priority. They are bringing in two.
Biggest recruit: ESPN 300 dual-threat quarterback Damion Terry is a capable thrower and runner, and he led his high school to a state title as a senior. Andrew Maxwell did not exactly lock down the starting quarterback job with his performance last season.
Biggest need: Donnell Kirkwood is a promising player at running back, but he struggled against some of the league’s better defenses and wore down late in the season. A complement is sorely needed.
Biggest recruit: Three-star running back Berkley Edwards is the younger brother of former Michigan receiver Braylon Edwards. Berkley is one of the Gophers’ highest-rated commitments, and running back is a position that lends itself to an easy transition.
Biggest need: Nebraska needs to return to its days of the Blackshirts, as the Huskers' defense was gashed on the ground all season. The Huskers need help along the defensive line.
Biggest recruit: Elite 11 finalist Johnny Stanton is a dual-threat quarterback, but he’s a much more polished passer than Taylor Martinez, who has taken his share of lumps since his flashy start in Lincoln.
Biggest need: Now that the Wildcats are a legitimate threat in the Big Ten under Pat Fitzgerald, the next step is to get better athletes to compete with Michigan and Ohio State. Fitzgerald is doing that with Ifeadi Odenigbo in 2012 and Godwin Igwebuike in 2013.
Biggest recruit: ESPN 300 dual-threat quarterback Matt Alviti had offers from some big programs including Notre Dame, but he chose nearby Northwestern. The Wildcats have an unsettled situation at quarterback, and as a local product Alviti could be called for by the fans if the quarterback play does not improve.
Biggest need: Linebacker was the biggest need for the Buckeyes, and after a shaky start Urban Meyer wrapped up a nice haul at the position with ESPN 150 products Trey Johnson and Mike Mitchell.
Biggest recruit: It’s a tie between Jalin Marshall and Dontre Wilson, who are separated by just a few spots in the ESPN 150. Both have game-breaking ability as a receiver or out of the backfield.
Biggest need: Despite significantly improved play from Matt McGloin in 2012, the Nittany Lions have not been blessed with quarterbacks the past decade, with the exception of a few good seasons from Michael Robinson and Daryll Clark.
Biggest recruit: While the class did field its share of decommitments, the damage would have been irreparable if No. 1 QB Christian Hackenberg bolted. By staying on, he instilled confidence in several other recruits to stay or join him in State College.
Biggest need: The quarterback situation at Purdue has been unsettled the past few seasons, which is not good when it comes to the most important position on the field.
Biggest recruit: An Elite 11 finalist, Danny Etling stuck with the Boilermakers through the coaching change. He will be looked at as the future of the program.
Biggest need: While the Badgers always have a strong stable of backs, losing Montee Ball is going to hurt, especially in the red zone. Wisconsin addressed it with top commitment Corey Clement.
Biggest recruit: The loss of Russell Wilson left a major void at quarterback, but the Badgers landed quarterback Tanner McEvoy on Monday. McEvoy is ranked No. 44 among juco prospects nationally and the expectation is he will contend for a starting job immediately.
