Despite selecting a pair of linebackers over the opening four rounds of last year’s draft, the Bears still need to find a viable, long-term solution in the middle of the defense.

While 2013 second-round pick Jon Bostic started nine games at middle linebacker as a rookie, Bears general manager Phil Emery has hinted on multiple occasions that Bostic may be better suited to one day move to outside linebacker.

“Maybe in the future his best position might be at one of those outside spots where he is filling from the backside and able to use his unique talents to the best of his ability,” Emery told ESPN 1000’s “Waddle and Silvy Show” last December.

Where Bostic lines up this year is up in the air. The Bears re-signed veteran inside linebacker D.J. Williams to a one-year deal, but Williams hasn’t been able to stay healthy, and appeared in just six games last season before landing on injured reserve with a torn pectoral muscle. Williams will turn 32 in July, and even if he does manage to shake off the injury bug, is likely a short-term fix at middle linebacker.

Khaseem Greene, a 2013 fourth-round draft choice, replaced Lance Briggs at weakside linebacker for seven games last year and seems earmarked for a role on special teams in 2014, unless the Bears suffer another rash of injuries at the position.

Former first-round pick Shea McClellin is expected to transition from defensive end to strongside linebacker.

So if the Bears are serious about potentially moving Bostic outside in the near future, the team needs to find help at inside linebacker, possibly in this draft.

Alabama’s C.J. Mosley is the consensus No. 1 inside linebacker in the 2014 draft class and could be available when the Bears pick at No. 14 overall in the first round. But with greater needs at safety, cornerback and defensive tackle, the Bears could wait until the middle rounds to address linebacker.

If that is the route the Bears decide to go, Monday is an important day because Stanford linebacker Shayne Skov is scheduled to hold a private pro day and run in front of scouts and NFL personnel people for the first time in the offseason. Skov, who declined an invitation to the Senior Bowl, pulled a hamstring before Stanford’s pro day that kept him sidelined. He also did not run the 40 yard dash in February at the NFL combine.

Skov has dealt with injuries throughout his college career, but the 6-foot-2, 245 pounder finished last season with better overall numbers than many of the other highly rated linebackers in the class of 2014, including Mosley.

Skov recorded 109 tackles, 5.5 sacks and 13 tackles for loss in 2013.

Another mid-round linebacker that could make sense for the Bears is Louisville’s Preston Brown, who began his college career at strong side linebacker before moving to the middle where he led the Cardinals in tackles back-to-back seasons. He had 98 stops, five sacks and 14 tackles for loss for Louisville last year.

“Moving to the middle taught me how to take control of the whole defense,” Brown said. “When you’re on the outside, you line up more at the line of scrimmage. In the middle, you sit back five yards and have to study what’s going on and make sure everybody is in the right place. You have to know everybody’s job.

"When you play Mike linebacker, you have to study a ton and learn the different shifts and formations. You have to be dialed in every snap, every game, because if you miss a check that could result in the other team scoring a touchdown. [Intelligence] is so important when you play middle linebacker.”

Brown has strong ties to new Bears assistant defensive line coach Clint Hurtt, who served as Louisville’s defensive line coach/recruiting coordinator from 2010-13.

“I love Coach Hurtt and he was one of my favorite coaches on the staff,” Brown said. “I would meet with him at least once a week and watch the run game and pick up some pass-rush moves from him. You could always talk to him if you had a problem. He was one of my favorite coaches.”
