Michigan Wolverines: Camren Williams

We're taking snapshots of each position group with each Big Ten team entering the spring. Up next: the linebackers.

Illinois: The Illini lose an All-Big Ten player in Jonathan Brown but still have decent overall depth at linebacker. Mason Monheim started every game at middle linebacker in 2013, and Mike Svetina started all but one game at the star position. Both players return as juniors. Svetina will move into Brown's spot on the weak side, while the other position could be filled by T.J. Neal, who recorded 38 tackles last season. Ralph Cooper has logged significant reps as a reserve, and Eric Finney gives Illinois some flexibility after playing the star position (safety/outside linebacker).

Indiana: This becomes a more significant position under coordinator Brian Knorr, who plans to use a 3-4 alignment. Indiana should have enough depth to make the transition as it returns two full-time starters from 2013 -- David Cooper and T.J. Simmons -- as well as two part-time starters in Forisse Hardin and Clyde Newton, who started the final four games of his freshman season. Like Simmons and Newton, Marcus Oliver played a lot as a freshman and provides some depth. The key here will be converting all the experience into sharper, more consistent play.

Iowa: If you're of the mindset that Iowa always reloads at linebacker, you can rest easy this spring. If not, keep a very close eye on what happens as the Hawkeyes begin replacing one of the more productive linebacker groups in team history: James Morris, Christian Kirksey and Anthony Hitchens. There are high hopes for sophomore Reggie Spearman, who played in 10 games as a freshman last fall. Spearman, junior Travis Perry and senior Quinton Alston enter the spring as the front-runners to take over the top spots. The biggest challenge could be building depth behind them with Cole Fisher and others.

Maryland: The good news is the Terrapins return three productive starters from 2013 in Cole Farrand, L.A. Goree and Matt Robinson, who combined for 233 tackles, including 19 for loss. The bad news is Maryland loses its top playmaker at the position in Marcus Whitfield, who recorded nine sacks and 15.5 tackles for loss last season. But the overall picture is favorable, and the depth should be strong when Alex Twine and Yannik Cudjoe-Virgil return from their injuries. Young players such as Abner Logan (37 tackles in 2013) will push for more time.

Michigan: There are a lot of familiar faces in new positions as Michigan not only has shuffled the roles of its defensive assistant coaches, but also its top linebackers. Standout Jake Ryan moves from strong-side linebacker to the middle, while junior James Ross III moves from the weak side to the strong side and Desmond Morgan shifts from the middle to the weak side. Joe Bolden, who had 54 tackles last season, can play both outside and inside, and players such as Ben Gedeon, Royce Jenkins-Stone and Allen Gant add depth. The talent is there for a big year if the position switches pan out.

Michigan State: It won't be easy to replace the Big Ten's top linebacker tandem in Max Bullough and Denicos Allen, not to mention Rose Bowl hero Kyler Elsworth, but Michigan State has some promising options. Ed Davis appears ready to step in for Allen after recording four sacks as a sophomore. Junior Darien Harris and two redshirt freshmen, Shane Jones and Jon Reschke, will compete at middle linebacker. Returning starter Taiwan Jones is back at the star position, and Mylan Hicks should be in the rotation. Depth is a bit of a question mark here entering the spring.

Minnesota: The Gophers lose key pieces in all three areas of the defense, and linebacker is no exception as two starters (Aaron Hill and James Manuel) depart. Minnesota will lean on Damien Wilson, who started in 12 games at middle linebacker in his first season with the Gophers and recorded 78 tackles. Junior De'Vondre Campbell seems ready to claim a starting spot after backing up Manuel last season. There will be plenty of competition at the strong-side linebacker spot, as Nick Rallis, De'Niro Laster and others are in the mix. Jack Lynn is backing up Wilson at middle linebacker but could work his way into a starting spot on the outside with a good spring.

Nebraska: Optimism is building for the Blackshirts in 2014, thanks in large part to the returning linebackers. The three players who finished last season as the starters -- David Santos, Michael Rose and Zaire Anderson -- all are back, as Rose will lead the way in the middle. Josh Banderas and Nathan Gerry also have starting experience and return for 2014. If younger players such as Marcus Newby develop this spring, Nebraska could have the Big Ten's deepest group of linebackers, a dramatic departure from the Huskers' first few years in the conference. Good things are happening here.

Northwestern: The top two playmakers return here in Chi Chi Ariguzo and Collin Ellis, who combined for seven interceptions and 11.5 tackles for loss in 2014. Northwestern's challenge is replacing the leadership Damien Proby provided in the middle. Ellis has shifted from the strong side to the middle, and Northwestern has moved safety Jimmy Hall from safety to strong-side linebacker. Drew Smith and Hall will compete for the third starting spot throughout the offseason. Sophomores Jaylen Prater and Joseph Jones should provide some depth.

Ohio State: Coach Urban Meyer has made it clear that Ohio State needs more from the linebackers, so it's a huge offseason for this crew, which loses superstar Ryan Shazier. The Buckeyes return starters at the outside spots in Curtis Grant and Joshua Perry, although competition will continue throughout the spring and summer. Redshirt freshman Darron Lee surprisingly opened spring practice Tuesday working with Grant and Perry on the first-team defense. Camren Williams appeared in all 13 games as a reserve and will be part of the rotation, along with Trey Johnson. Meyer said last month that the incoming linebacker recruits won't redshirt, which means an opportunity for mid-year enrollee Raekwon McMillan.

Penn State: Linebacker U is looking for more bodies at the position after struggling with depth issues throughout 2013. The Lions lose leading tackler Glenn Carson but bring back two players, Mike Hull and Nyeem Wartman, who started most of the season. The new coaching staff is counting on Hull to become a star as a senior. Brandon Bell, who appeared in nine games and recorded 24 tackles as a freshman, will compete for a starting spot along with Gary Wooten. Penn State hopes Ben Kline can stay healthy as he provides some experience, and incoming freshman Troy Reeder could enter the rotation right away.

Purdue: Expect plenty of competition here as Purdue loses leading tackler Will Lucas and must get more consistent play from the group. Joe Gilliam started for most of the 2013 season and should occupy a top spot this fall. Sean Robinson also brings experience to the field, and Ryan Russell could fill more of a hybrid linebacker/defensive end role this season. Redshirt freshman Danny Ezechukwu is an intriguing prospect to watch this spring as he aims for a bigger role. Ezechukwu is just one of several younger players, including decorated incoming recruit Gelen Robinson, who have opportunities to make a splash.

Rutgers: The Scarlet Knights return a good deal of production here with Steve Longa and Kevin Snyder, who combined for 219 tackles, including 15 tackles for loss and five sacks. Quentin Gause also is back after racking up 53 tackles (8.5 for loss) in a mostly reserve role last season. Gause likely will claim the starting strong-side linebacker spot as Jamal Merrell departs. The starting spots are seemingly set, so Rutgers will look to build depth with Davon Jacobs, who had 30 tackles as a reserve last season, and L.J. Liston, both sophomores.

Wisconsin: Do-it-all linebacker Chris Borland is gone, along with Ethan Armstrong and Conor O'Neill, so Wisconsin must replace three of its top four tacklers from 2013. Derek Landisch and Joe Schobert can be penciled in as starters, along with Michael Caputo, who played mostly safety last season but should slide into one of the outside spots. Marcus Trotter brings experience to the rotation. The spotlight will be on younger linebackers such as Vince Biegel, who had 25 tackles last season, as well as dynamic sophomore Leon Jacobs and Alec James, a decorated recruit who redshirted in 2013.
Believe it or not, spring football in the Big Ten is just around the corner. Several teams moved up their spring practice dates, and three of them -- Maryland, Michigan and Northwestern -- will take the field next week.

Spring ball is all about development, and some position groups need to make significant strides before the summer.

Here are five ...

Illinois' defensive line: Coach Tim Beckman kept his defensive staff in place for what should be a make-or-break season in Champaign. Coordinator Bill Cubit's presence should stabilize the offense despite the loss of quarterback Nathan Scheelhaase, so the season likely hinges on whether the defense improves. There are some nice returning pieces at linebacker, but the line needs a boost after Illinois finished last in the Big Ten and 116th nationally against the run. Lineman Paul James, who originally signed with Illinois in 2013 but delayed his enrollment until January, is among those who will take the field this spring. There's plenty of competition throughout the line, and while help arrives this summer with Jihad Ward and others, Illinois needs some linemen to emerge right away.

Michigan's offensive line: Despite a first-round draft pick at left tackle (Taylor Lewan), Michigan's front five struggled mightily during the 2013 season, as young players didn't blossom quickly enough and the team couldn't consistently run the ball between the tackles. Coordinator Al Borges took the fall, but line coach Darrell Funk and his group will be under the microscope when the Wolverines begin spring practice Feb. 25. Michigan started nine different linemen in 2013 and used five lineup combinations. As tackles Lewan and Michael Schofield both depart, every position is up for grabs this spring. It will also be interesting to see how new coordinator Doug Nussmeier makes an impact on the line.

Minnesota's quarterbacks: At least nine Big Ten teams will have true quarterback competitions this spring, but arguably none has as much mystery as Minnesota. Philip Nelson's transfer following the season creates a wide-open race between Mitch Leidner, Chris Streveler, Conor Rhoda and Dimonic Roden-McKinzy, a dynamic, dual-threat quarterback who enrolled mid-year and will participate in spring practice. Leidner is the only quarterback with college game experience, appearing in 10 games last fall and recording 1,026 yards (619 passing, 403 rushing). Perhaps Leidner separates himself, but no matter what, Minnesota wants a clearer picture coming out of the spring.

Ohio State's linebackers: Coach Urban Meyer has made it very clear that Ohio State's linebacker play has fallen short of program standards. Meyer singled out the linebacker position in the 2014 recruiting class, saying on national signing day, "Far too many mistakes have been made in either lack of development or whatever, and it's just not where we need to be." Ohio State loses by far its best linebacker in Ryan Shazier, so there's pressure on returnees such as Curtis Grant, Joshua Perry and Camren Williams, as well as newcomers such as five-star prospect Raekwon McMillan, a mid-year enrollee who will be on the field this spring. Meyer said there are no redshirt plans for McMillan or the other three linebackers in the 2014 class.

Wisconsin's wide receivers: The Badgers' quarterback competition likely will garner more attention, but whoever emerges under center will need more options in the passing game. Jared Abbrederis has been Wisconsin's wide receiving corps for the past two season, and he'll be playing in the NFL this fall. You can only get by so much with pass-catching tight ends and running backs, so receivers coach Chris Beatty and his group need a strong spring session. Jordan Fredrick, Kenzel Doe and Alex Erickson lead the returnees, but Wisconsin needs young players such as speedster Robert Wheelwright to emerge. Help is on the way this summer as several promising recruits arrive, but Wisconsin can't pin its hopes exclusively on incoming freshmen.

With any conference there will always be battles on the recruiting trail within the Big Ten. Coaching changes, different philosophies and geographic location all factor in to who battles who.

Here is a look at the top five Big Ten recruiting rivalries.
