OSU Buckeyes

Every Big Ten team will rely on a handful of freshmen (sometimes more than a handful) to fill key roles when the 2013 season rolls around. Which newcomers will make the biggest impact in the league?

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.

Illinois
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.

Indiana
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.

Iowa
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.

Michigan
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.

Michigan State
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.

Minnesota
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.

Nebraska
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.

Northwestern
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.

Ohio State
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.

Penn State
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.

Purdue
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.

Wisconsin
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.
