B1G spring position outlook: Defensive line

2/24/2015

As spring practice opens in Ann Arbor and Evanston this week, we’re comparing position groups around the Big Ten. Defensive line is up now. For others in the series, click here:

Best of the best: Michigan State

Shilique Calhoun's return guarantees the Spartan Dawgs will retain their bite up front. Starting defensive tackles Lawrence Thomas and Joel Heath also will be back, and Malik McDowell could be ready to take a leap forward after getting his feet wet as a true freshman. Michigan State does have to replace four-year starter Marcus Rush, but it has Demetrius Cooper groomed to take on a much larger role. This is a deep and talented bunch anchored by a potential NFL first-rounder in Calhoun.

Next up: Ohio State

You could consider the Spartans and Buckeyes Nos. 1 and 1A here. Ohio State still has reigning Big Ten defensive player of the year Joey Bosa at defensive end, along with Adolphus Washington at defensive tackle. But the Buckeyes did lose All-America defensive tackle Michael Bennett and defensive end Steve Miller, and they weren't very deep at the position last season. Incoming true freshmen Dre'Mont Jones and Jashon Cornell could be asked to contribute right away at end, and the hope is someone from a group of redshirt sophomores -- Donovan Munger, Michael Hill and Tracy Sprinkle -- can move in next to Washington.

Sleepers: Michigan and Minnesota

The Wolverines replace both of their starting defensive ends from last season in Frank Clark and Brennen Beyer, though Clark was dismissed from the team before the season ended. Michigan should be in very good shape at defensive tackle with Willie Henry, Bryan Mone, Ryan Glasgow and Chris Wormley, and it could be Taco Charlton's time to shine at defensive end. New defensive coordinator D.J. Durkin had players on the front four gain weight this offseason in anticipation of possibly some more 3-4 looks this fall.

Minnesota lost two starters in tackle Cam Botticelli and Michael Amaefula, but remember the line dealt with some early injuries last season and still excelled. Defensive end Theiren Cockran returns, along with promising rising sophomore Steven Richardson at tackle, while Scott Ekpe and Alex Keith are back from their injuries. The Gophers like their depth here, too.

Problem for contenders: Nebraska and Wisconsin

These may not be problems as much as question marks, but both the Huskers and Badgers need some new players to step up this spring.

Nebraska looks all set in the middle with Maliek Collins and Vincent Valentine, but Randy Gregory's departure leaves a huge hole at defensive end. Greg McMullen and Jack Gangwish return starting experience there, but they won't remind anyone of Gregory nor scare many opposing offensive tackles the same way he did.

Wisconsin, meanwhile, must replace two members of its three-man starting front in departing seniors Warren Herring and Konrad Zagzebski. Chikwe Obasih and Arthur Goldberg gained a lot of experience, but the Badgers will probably need a young guy like Alec James to improve this spring to solidify the entire unit.
