Of the three players signed by the Ravens on Monday, only guard Will Rackley has starting experience.
Rackley was a starting left guard for the Jacksonville Jaguars in 2011 and 2013, sitting out 2012 due to injury. Rackley has 25 games as a starter under his belt, though he struggled to the point where the Jaguars decided to release him this past March.
At 6-3, 310 pounds, Rackley is an athletic guard that's still young in his career. Drafted in the third-round by the Jaguars in the 2011 draft, Rackley played for an organization that didn't have much help around him, outside of Eugene Monroe (before the trade with the Ravens) at left tackle and Maurice Jones-Drew at running back.
In Baltimore, assuming the line is on the same page and the skill position players are able to damage, Rackley could have an opportunity to succeed.
Given that he's been a starter, the chance for Rackley to step in at left guard to move Kelechi Osemele to right tackle does exist. Bringing in Rackley gives the Ravens this option without having to break the bank. Rick Wagner will still be considered the starting right tackle, but you have to think this scenario will be tried out during OTAs, minicamp and training camp.
Rackley is familiar with the zone blocking principles, seeing that the Jaguars switched to that scheme for the 2013 season. He's also used to playing next to Monroe.
This move figures to be a win-win for the Ravens. In a best-case scenario, Rackley offers game experience and the chance at filling the fifth offensive line spot. Worst-case, he becomes a quality backup option that can step in if needed.
