Noteboom has 17 games worth of experience and he's been solid. The problem is Edwards who is a marginal OG. Under strength, plays too high, and generally inconsistent technique. He should be playing better by now and isn't.
It's pretty obvious they are going to allow Havenstein to playout his contract and become a comp pick. I think they have the same plans for Edwards. Jackson looks like he could be an upgrade over Havenstein next year. Arcuri is the kind of late round OT you can develop into a decent swing OT starting next year.
If Jack Snyder looks like he should in TC that would give them two reserve OGs in Shelton and Snyder. It looks like the Rams have gotten away from Kromer's failed idea of drafting OTs to convert into OGs. They take too long to develop. Now they are drafting OGs to play OGs and OTs to play OT. Bruss could kick outside to RT in an emergency but he entered the draft as an OG. It was clear from the draft war room video that Bruss is expected to start at ROG.
If they trade it will be for an edge to replace Von.
