Since the start of the offseason, the Los Angeles Rams have been one of the busier teams in the league in retooling their roster coming off the first playoff appearance in over a decade. This has seen the Rams make several splash moves to improve their defensive unit for the 2018 campaign.

However, there haven't been many moves made on the offensive side of the ball, which saw a vast improvement this past season in the first year under head coach Sean McVay. With that in mind, the Rams have brought back center John Sullivan on a two-year, $15 million deal, according to Ian Rapoport of The NFL Network.

The 32-year-old had just wrapped up his first season with the Rams where he made a tremendous impact in helping improve the play along the offensive line. His presence along with Pro Bowl left tackle Andrew Whitworth helped bring stable blocking in both in passing and running situations.

He had joined the Rams on a one-year, deal worth nearly $1 million last offseason to join McVay in Los Angeles as the two worked together with the Washington Redskins in the 2016 campaign. Sullivan proved to be a major asset in helping Jared Goff take a significant leap in his development this past season with his familiarity playing in McVay's offensive scheme.

There is some risk with the move given that he has an injury history after missing the entire 2015 campaign with back issues, but he has shown to be more than worth keeping around. His presence should help further allow the Rams to possibly take another step forward next season.

There had been some interest from the Washington Redskins and New York Giants, but Los Angeles may have done the wise thing by offering him a lucrative contract to keep aboard for the next two years. There could a few more moves ahead for the Rams in free agency to add more pieces to their promising puzzle.
