The Rams have signed 25-year old center Jason Brown to a 5-year, $37.5 million dollar contract.  Brown played in all 16 games for the Ravens last season and he started all of them.  He has now played in 54 games (45 starts) in his 4-year, NFL career.  Brown is a big guy at 6′3″, 320 pounds and he was considered the best interior offensive lineman available in free agency so this was a great move for the Rams.
