Jonah Jackson's issue is durability, which the Rams knew when they signed him. It was a poor signing because they were wrong in their estimation that Avila could play Center. This left them with three starting level Guards, and the one on the depth chart is making starter money.
So what I would do in camp next year is move Jackson officially to the pivot. That is the position he needs to win in order to start. Period. He will also be the first depth option potentially for both Guard spots, though that depends on the relative performance of both Limmer and Dedich in camp next year. In other words if Limmer loses a narrow battle to Jackson at Center, or beats Jackson out at Center, then Jackson is first man off the bench for both Guard spots.
It may be possible to move Jackson if some team is interested in him. There has been a focus by teams of late in building the interior of their lines. But the Rams cannot afford to make another salary dump move in an offseason where they are already doing that with Kupp. They want to contend, not use all their resources to bandage the roster. It is ok to have extra quality on the interior OL for 2025 if they can get that slot role upgraded and add those defensive pieces we need to make the defense great again.
