OG Jonathan Cooper
Cooper signed with the Raiders this offseason after missing most of the 2018 season with a torn bicep, but he was released just after the season started. He wasn’t good in the four games he started for Arizona last year, but he played well for the Cowboys in 2017, allowing just two sacks in 13 starts.
As a run blocker, Cooper is fairly good, but he struggles in pass protection – which may not be a good recipe for the Rams.
