The Rams offensive line has yet to put its best foot forward as a unit and I think the depth on the offensive line is actually better than the play we have seen from some of the backups in the preseason games. A lot of guys are playing in alternate positions without the cohesiveness of playing together for a while and the line makeup does not truly reflect how things will emerge if injuries occur. Essentially in the first 2 preseason games, the O-line has been without their two best players in Long and Saffold plus Wells was out for the first game as well. The only starters that have played any significant snaps are Barksdale and Robinson with Wells getting some time in game 2. Robinson is learning and will only get better (Even though he has had a few bad moments in pass pro, his talent is obvious).
As we all know, with good health the Starting 5 should be: Long, Robinson, Wells, Saffold, and Barksdale. After that, the final 4 by my guess would be Joseph, Barnes, Bond & Person - Plus Hooey if they keep 10 with Van Dyk and Rhaney to the PS. If they only keep 9 then it could be Hooey, Van Dyk, and Rhaney to the PS assuming they all clear waivers. Noted below are estimated depth charts purely based on my humble opinion. From my perspective the Rams actually have some pretty good depth and a lot of flexibility with their starters and backups.
