Big Ten position rankings: Offensive line
Posted by ESPN.com's Adam Rittenberg
Everything on offense starts with what happens up front, and line play will make or break the season for several Big Ten teams. The league loses a handful of standout linemen, including Rimington Trophy winner A.Q. Shipley, but several teams should reload nicely.
There's a lot to like about the top three, and I don't see any truly bad units in the league.
1. Iowa -- Shonn Greene was the nation's most dominant running back last year, but he had plenty of help. Iowa returns three starters and several key reserves from a line that propelled Greene to 13 consecutive 100-yard rushing performances. Junior Bryan Bulaga is the league's premier left tackle, while Kyle Calloway provides depth on the other side. The Hawkeyes boast more guard depth than any Big Ten team, a group that includes Dace Richardson, who has resurrected his career after a string of injuries.
2. Ohio State -- A major disappointment in 2008, Ohio State's line should be much improved thanks to experience, the addition of guard Justin Boren and some excellent recruiting. Boren brings a much-needed spark to the line and impressed just about everyone this spring. Center Mike Brewster is a year older, and senior Jim Cordle has shown impressive versatility in shifting to right tackle. The left tackle spot concerns me a bit, but Ohio State has recruited extremely well here.
3. Wisconsin -- The Badgers lose starting guards Andy Kemp and Kraig Urbik, but they always find a way to control the line of scrimmage and return several key pieces. Center John Moffitt and left tackle Gabe Carimi will contend for All-Big Ten honors, and Bill Nagy looks solid at one of the guard spots. If right tackle Josh Oglesby takes a step forward and lives up to his potential, Wisconsin will once again have one of the league's top lines.
4. Northwestern -- The team hopes its skill-position losses will be offset by a much better offensive line, which returns four starters. Northwestern did a good job of limiting sacks last year but should be much better at staying on blocks and buying time for athletic quarterback Mike Kafka. Left tackle Al Netter and center Ben Burkett are both All-Big Ten candidates, and the Wildcats boast plenty of depth after recruiting extremely well to this position.
5. Michigan -- No group will make a bigger jump in Year 2 of the spread offense than the line, which returns four starters. Michigan should be very solid up the middle with center David Molk and guards Stephen Schilling and David Moosman. If the Marks (Ortmann and Huyge) hold up at the tackle spots, a run game led by Brandon Minor will surge. Despite several player departures, Michigan has recruited several standout linemen who will provide depth this fall.
6. Michigan State -- I like the Joels (Foreman and Nitchman), and left tackle Rocco Cironi returns from a shoulder injury, but this group still needs to prove itself. Despite Javon Ringer's success last fall, the line was just average and must fill several gaps. Hopes are high for J'Michael Deane and Jared McGaha after spring ball, and if those players make progress Michigan State will move up the list.
7. Penn State -- The line rivals the secondary as Penn State's biggest concern entering the fall. In addition to Shipley, the Lions lose tackle Gerald Cadogan and guard Rich Ohrnberger. Only one starter (right tackle Dennis Landolt) returns to the same position he occupied in 2008. Stefen Wisniewski will be fine at center, but Penn State needs tackle DeOn'tae Pannell and others to make a lot of progress during camp.
8. Illinois -- With so much talent at the skill positions, expectations will be high for the Illini line, which drew mixed reviews in 2008. Right guard Jon Asamoah will contend for All-Big Ten honors, and Illinois really likes young right tackle Jeff Allen. The team must fill a big hole at left tackle, though veteran Eric Block slides over from guard to center. This could end up being a very respectable group.
9. Minnesota -- Perhaps no offensive line in the Big Ten intrigues me more than Minnesota's, which is going through a major transition in both scheme and technique with assistant Tim Davis. The Gophers are returning to their roots as a power-run offense, but they'll have to adjust quickly to all the changes. Left tackle Matt Stommes could be a pro prospect if things fall right, and the mammoth Jeff Wills lines up on the other side of the line. Notre Dame transfer Matt Carufel joins the mix as a starting guard.
10. Purdue -- Injuries decimated the two-deep last year, and Purdue used seven different starting lineups up front. The Boilers are much healthier entering the fall and should be much better. Young players like right guard Ken Plue gained valuable experience last fall, and he rejoins veterans Jared Zwilling, Zach Reckman and Zach Jones. The big question is how quickly the group jells as Purdue wants to stress the run game more this fall.
11. Indiana -- Much like Purdue, injuries hit Indiana's line especially hard last fall. The Hoosiers have two proven veterans in left tackle Rodger Saffold and center Pete Saxon, both of whom have started for three seasons. If those two can lead the way and young players like Justin Pagan and Will Matte continue to develop, Indiana will be much improved here.
