Penn State Nittany Lions: Darius Latham
Illinois: This is a significant concern for the Illini, especially after the recent departure of Houston Bates, who started last season at the Leo (defensive end/outside linebacker) spot. Illinois also loses its other starting defensive end, Tim Kynard. The team will rely heavily on junior-college players such as Jihad Ward and Joe Fotu, but it also needs holdovers like Dawuane Smoot and Paul James III to step up on the perimeter. Illinois returns more experience inside with Austin Teitsma and Teko Powell, but there should be plenty of competition, especially with the juco arrivals, after finishing 116th nationally against the run.
Indiana: The anticipated move to a 3-4 alignment under new coordinator Brian Knorr creates a different dynamic for the line this spring. Indiana must identify options at the all-important nose tackle spot, and possibilities include sophomores Ralphael Green and Darius Latham, both of whom are big bodies. Nick Mangieri had a nice sophomore season and should be in the mix for a starting job on the perimeter (end or outside linebacker), while David Kenney could be a good fit as a 3-4 end. Defensive end Ryan Phillis is the team's most experienced lineman, and Zack Shaw also has some starting experience.
Iowa: This group should be the strength of the defense as Iowa returns three full-time starters -- tackles Carl Davis and Louis Trinca-Pasat, and end Drew Ott -- as well as Mike Hardy, who started the second half of the season opposite Ott. End Dominic Alvis departs, but Iowa brings back almost everyone else from a line that allowed only eight rushing touchdowns in 2013. Junior Darian Cooper could have a bigger role and push for more playing time inside, and Nate Meier provides some depth on the perimeter after recording two sacks in 2013. Iowa is in good shape here.
Maryland: The Terrapins employ a 3-4 scheme and appear to be in good shape up front, as reserve Zeke Riser is the only rotation player to depart. Andre Monroe leads the way at defensive end after an excellent junior season in which he led Maryland in both sacks (9.5) and tackles for loss (17). Quinton Jefferson started at defensive end last season and recorded three sacks. There should be some good competition this spring at nose tackle between Keith Bowers and Darius Kilgo, both of whom had more than 30 tackles last season. The challenge is building greater depth with players such as end Roman Braglio.
Michigan: If the Wolverines intend to make a big step in 2014, they'll need more from the front four, which didn't impact games nearly enough last fall. Michigan's strength appears to be on the edges as veteran Frank Clark returns after starting every game in 2013 and recording a team-high 12 tackles for loss. Brennen Beyer, who started the second half of last season, is back at the other end spot, and Michigan has depth with Mario Ojemudia and Taco Charlton. There are more questions inside as Willie Henry, Chris Wormley and others compete for the starting job. Young tackles such as Henry Poggi and Maurice Hurst Jr. also are in the mix, and Ondre Pipkins should be a factor when he recovers from ACL surgery.
Michigan State: The Spartans return the best defensive end tandem in the league as Shilique Calhoun, a second-team All-American in 2013, returns alongside Marcus Rush, one of the Big Ten's most experienced defenders. Joel Heath, Brandon Clemons and others provide some depth on the perimeter. It's a different story inside as MSU loses both starters (Micajah Reynolds and Tyler Hoover), as well as reserve Mark Scarpinato. Damon Knox, James Kittredge and Lawrence Thomas, who has played on both sides of the ball, are among those who will compete for the starting tackle spots. If Malik McDowell signs with MSU, he could work his way into the rotation.
Minnesota: Defensive tackles like Ra'Shede Hageman don't come around every year, and he leaves a big void in the middle of Minnesota's line. The Gophers will look to several players to replace Hageman's production, including senior Cameron Botticelli, who started opposite Hageman last season. Other options at tackle include Scott Ekpe and Harold Legania, a big body at 308 pounds. Minnesota is in much better shape at end with Theiren Cockran, arguably the Big Ten's most underrated defensive lineman. Cockran and Michael Amaefula both started every game last season, and Alex Keith provides another solid option after recording five tackles for loss in 2013.
Nebraska: Other than MSU's Calhoun, Nebraska returns the most dynamic defensive lineman in the league in Randy Gregory, who earned first-team All-Big Ten honors in his first FBS season. If the Huskers can build around Gregory, they should be very stout up front this fall. Nebraska won't have Avery Moss, suspended for the 2014 season, and players such as Greg McMullen and junior-college transfer Joe Keels will compete to start opposite Gregory. The competition inside should be fascinating as junior Aaron Curry and sophomore Vincent Valentine both have starting experience, but Maliek Collins came on strong at the end of his first season and will push for a top job.
Northwestern: It will be tough to get a clear picture of this group in the spring because of several postseason surgeries, but Northwestern should be fine at defensive end despite the loss of Tyler Scott. Dean Lowry, Ifeadi Odenigbo and Deonte Gibson all have significant experience and the ability to pressure quarterbacks. Odenigbo, who had 5.5 sacks as a redshirt freshman, could become a star. The bigger questions are inside as Northwestern must build depth. Sean McEvilly is a solid option but must stay healthy. Chance Carter and Max Chapman are among those competing for starting jobs at tackle.
Ohio State: A total mystery last spring, the defensive line should be one of Ohio State's strengths in 2014. Noah Spence and Joey Bosa could become the Big Ten's top pass-rushing tandem, and the Buckeyes have depth there with Jamal Marcus, Adolphus Washington and others. Returning starter Michael Bennett is back at defensive tackle, and while Joel Hale might move to offense, there should be enough depth inside with Tommy Schutt, Chris Carter and Washington, who could slide inside. Nose tackle is the only question mark, but new line coach Larry Johnson inherits a lot of talent.
Penn State: Like the rest of the Lions defense, the line struggled at times last season and now much replace its top player in tackle DaQuan Jones. The new coaching staff has some potentially good pieces, namely defensive end Deion Barnes, who won 2012 Big Ten Freshman of the Year honors but slumped as a sophomore. Barnes and C.J. Olaniyan could form a dangerous pass-rushing tandem, but they'll need support on the inside, where there should be plenty of competition. Austin Johnson will be in the mix for a starting tackle spot, and early enrollees Tarow Barney and Antoine White also should push for time. Anthony Zettel provides some depth on the perimeter.
Purdue: The line endured a tough 2013 campaign and loses two full-time starters (tackle Bruce Gaston Jr. and end Greg Latta), and a part-time starter (end Ryan Isaac). Competition should be ramped up at all four spots this spring. Senior end Ryan Russell is the most experienced member of the group must take a step this offseason. Evan Panfil and Jalani Phillips will push for time at the end spots, along with Kentucky transfer Langston Newton. The group at tackle includes Ryan Watson and Michael Rouse III, both of whom started games in 2013.
Rutgers: Keep a close eye on this group in the spring as Rutgers begins the transition to the Big Ten. The Scarlet Knights lose two starters in end Marcus Thompson and tackle Isaac Holmes, as well as contributor Jamil Merrell at tackle. Darius Hamilton provides a building block on the inside after recording 4.5 sacks and 11.5 tackles for loss in 2013, and end Djwany Mera is back after starting throughout last season. David Milewski played tackle last year, but both he and Hamilton likely need to add weight for their new league. Rutgers has some talent in the younger classes and needs players such as Sebastian Joseph, Kemoko Turay and Julian Pinnix-Odrick to emerge.
Wisconsin: Linebacker Chris Borland is the biggest single departure for the Badgers' defense, but the no position group loses more than the line. Wisconsin must replace several mainstays, most notably nose tackle Beau Allen, who performed well in the first year of the 3-4 set under coordinator Dave Aranda. Senior Warren Herring will step in for Allen after three years as a reserve. Konrad Zagzebski is a good bet to fill one of the end spots, but there will be plenty of competition with players such as Jake Keefer, James Adeyanju, Arthur Goldberg and Chikwe Obasih.
True freshmen are having a bigger and bigger impact throughout college football these days, as coaches are either becoming less afraid to throw their youngsters into the fire or are facing fewer options.
1. Penn State: The Nittany Lions are starting just one true frosh, but he's a guy with a little bit of importance to the team's fortunes: quarterback Christian Hackenberg. The 18-year-old has had some ups and downs but is on pace for a 3,000-yard season. Tight end Adam Breneman and receiver Richy Anderson have also played in every game, with one start each. Von Walker, Brandon Bell and Jordan Smith are among others who have seen time for coach Bill O'Brien, who doesn't have the luxury to redshirt many guys with the Lions' depth issues.
2. Nebraska: The Huskers' defense is young, all right. So young that two true freshmen are starting at linebacker for Bo Pelini in Josh Banderas and Nathan Gerry. They rank fourth and fifth on the team in tackles, and Banderas is handling a leadership position as the middle linebacker.
3. Ohio State: Urban Meyer says Ohio State doesn't redshirt. If you're ready, you play. Technically, the Buckeyes don't start any true freshmen, but Dontre Wilson has already made a big impact as a runner, receiver and kick returner. Several other first-year players dot the two-deep, such as safety Vonn Bell and defensive lineman Joey Bosa, and running back Ezekiel Elliott ran for more than 100 yards and scored two touchdowns last week versus Florida A&M.
4. Indiana: No surprise to see the Hoosiers on this list, since coach Kevin Wilson has played as many true freshmen as any coach in the country the past few years. That means Indiana finally has some veterans, but Wilson is starting T.J. Simmons at linebacker and getting contributions from Darius Latham on the defensive line, Antonio Allen in the secondary and Marcus Oliver and Clyde Newton at linebacker.
5. Wisconsin: The Badgers are mostly an experienced, veteran team. The one exception is in the secondary. Sojourn Shelton is starting at cornerback for the Badgers, while Jakarrie Washington and Nate Hammon are top reserves in the defensive backfield.
Tom Luginbill, RecruitingNation's senior national recruiting analyst, has identified five names to remember among incoming freshmen who will enroll this summer. Luginbill already singled out Ohio State cornerback Eli Apple as an early enrollee who could make a difference this fall.
Two Big Ten freshmen make Luginbill's new list. Neither needs much of an introduction.
Michigan running back Derrick Green is expected to compete right away for a starting job. Ranked by RecruitingNation as the No. 5 running back (No. 38 overall player) in the 2013 class, Green will be Michigan's best option in the backfield as the Wolverines go back to a more traditional pro-set scheme that will emphasize power running. No Michigan back distinguished himself this spring, and Green likely will face the most competition from Fitzgerald Toussaint, who comes off of leg surgery.
Luginbill also likes the impact potential of Ohio State incoming freshman Dontre Wilson, who could be fill the so-called "Percy position" in Urban Meyer's spread offense in Columbus. Wilson, a speedster from Texas who picked Ohio State ahead of Oregon and Texas, brings playmaking ability to an offense that needs more of it other than star quarterback Braxton Miller. Although Jordan Hall returns to the mix after battling injuries throughout 2012, Wilson could have a significant role in the offensive vision with a strong preseason showing.
What other incoming freshmen (non-early enrollees) could make an impact in the Big Ten this season?
Here are a few:
Penn State QB Christian Hackenberg: It'll be Hackenberg or junior-college transfer Tyler Ferguson starting for the Lions in their season opener against Syracuse. Unless Ferguson creates significant separation in camp, Hackenberg likely will be a factor this season.
Indiana DT Darius Latham: The Hoosiers need help along their defensive line, and could turn to Latham right away. A four-star prospect with good size and athleticism (played basketball in high school), Latham should be part of the mix up front at IU.
Michigan State RB Delton Williams: The Spartans need help in the backfield after no one really emerged this spring, and the coaches moved backup middle linebacker Riley Bullough to offense for help. There's a good chance Michigan State turns to an incoming freshman and Williams, the team's highest-rated recruit in the 2014 class according to RecruitingNation, will have a golden opportunity in camp.
Ohio State S Vonn Bell: Unlike the other freshmen listed here, Bell doesn't play a position where Ohio State has an overly pressing need. But he might be too talented to keep off of the field, especially when the Buckeyes go to their nickel and dime packages.

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.
