The Ravens offensive line was one of their biggest weaknesses in 2013, but they've done a good job of upgrading it this offseason.
Eugene Monroe has locked down the left tackle spot after inking a long-term, $37 million extension this offseason.
Kelechi Osemele and Marshal Yanda are likely retaining their starting guard spots after holding them for the past two years. Both players have played at a high level at points in their career, but they both struggled in 2013.
At center, Jeremy Zuttah was acquired via a trade from the Tampa Bay Buccaneers in the offseason. Ravens head coach John Harbaugh has already stated Zuttah will replace Gino Gradkowski as the starting center.
Rick Wagner is the early favorite to start at right tackle after Michael Oher departed in free agency, and the Ravens opted not to sign or draft another tackle this offseason.
They appear to be confident that Wagner can lock down that RT spot, despite the fact he played in just 131 offensive snaps in 2013 as a rookie fourth-rounder out of Wisconsin.
But even if he can be just a decent starter, there's no real depth behind him or Monroe at offensive tackle.
David Mims is the only backup tackle with previous experience, but he's a career backup who's never registered an offensive snap.
North Carolina's James Hurst was signed as an undrafted free agent, and as of now, he and Mims are the two projected backup tackles behind Monroe and Wagner.
That's scary situation could become disastrous if Baltimore were to lose either Wagner or Monroe to injury. The Ravens badly need to sign another tackle to at least provide some veteran depth at such a thin position.
David Stewart, Bryant McKinnie, Ryan Harris, Eric Winston, J'Marcus Webb and Tyson Clabo are some of the notable tackles who are still free to sign with any team.
At least one of them needs to be getting a call from the Ravens soon.
