Los Angeles had brought in Sullivan for a visit last week in hopes of being able to sign him to a deal. The team possessed a pressing need at the position after deciding to part ways with Tim Barnes just prior to the start of the free agency period. Barnes had started all 32 regular season games over the last two seasons.
Sullivan started 93 games in six seasons with the Minnesota Vikings before being sidelined for the entire 2015 campaign due to a back injury. He spent last year as the backup for the Washington Redskins Sullivan played the 2016 season under new Rams' head coach Sean McVay when he was the Redskins offensive coordinator.
The 31-year-old has proven in the past to be more than a serviceable option at that position as Pro Football Focus graded him 82 or better from 2011-14 during his tenure with the Vikings. In fact, he was one of the big pieces up front that helped Adrian Peterson record 2,097 rushing yards for the 2012 season, which earned him a selection to the Pro Football Writers Association's All-Pro team.
The Rams have put forth a concerted effort in retooling their offensive line prior to the NFL Draft later this month. The team has already added former Pro Bowl left tackle Andrew Whitworth on a three-year, $36 million deal in free agency. Whitworth has been regarded as one of the top players at his position over the last several seasons.
This move has subsequently shifted Greg Robinson to the right side of the offensive line pushing Rob Havenstein inside to right guard. It also displaces Jamon Brown from his starting role while Rodger Saffold is expected to remain as the starting left guard. Los Angeles is hoping all of this shuffling along the offensive line could help quarterback Jared Goff see some significant progression in his second season while making way for a bounce-back campaign from Todd Gurley.
With the draft just a few weeks away, there could be a few more additions involving the offensive line ahead.
