The Baltimore Ravens are hopeful they can retain left tackle Eugene Monroe, according to team sources, after acquiring him from Jacksonville in a midseason trade.

Monroe is eligible for unrestricted free agency in March, but keeping him is a priority for Baltimore, which has gone through some instability at left tackle since Hall of Famer Jonathan Ogden retired.

The Ravens parted with a fourth and fifth round pick to land Monroe -- a steep price for a “rental” and especially steep for a team that prizes draft picks as the Ravens do -- and with right tackle Michael Oher’s future very much in doubt with the team, the team will attempt to secure Monroe long-term when then season ends, sources said.

Oher, a former first-round pick, has shown he can not play left tackle and even as a right tackle, struggles in pass protection and commits a lot of penalties. Contract talks with Oher prior to the season yielded no real progress, sources said, and the team is unlikely to make Oher among the highest-paid right tackles in the league.

Monroe, after an adjustment period, has fit in well in Baltimore on the field and off and if the Ravens can keep him at left tackle -- the team has gone on a 5-2 surge with him manning the position -- and invest some of the money Oher would command there, it opens up other opportunities.

Guard Kelechi Osemele, who is on IR with a back injury, has shown an ability to thrive at right tackle as well, and if the Ravens make that move and then draft a guard on the second day of the draft, it could be a cost-effective and prudent tact to take rather than trying to find another left tackle.
