4 of our 5 starting OL are pending FAs after this season. So I think it is correct to say that out of those 4 what the Rams think of the OT looms large in their decision making. Jackson's contract btw runs through the 2027 season and he's had those blood clots looming, so his status may concern the Rams more than they are letting on. Which means the Rams may be planning to use this draft to reset the OL the way they want it.
Also this draft is strong on the interior. Tackles seem to be weaker at the top than normal, due to the top dudes having short arms and possibly adding to the stronger guard group.
I doubt the Rams pay more than 3x of their OL. With Jackson already being paid, that means they can pay 2 of the 4 who are pending FA. Also it makes sense that they would potentially add a couple OL pieces to this unit in the draft, which would improve the depth quality and provide them with a one year look to see how those rooks fit in their plans.
On top of all this the swing OT role is a key depth role that it is very risky to not fill. So we could say that it is likely the Rams require 3x OL brought in over the 2026 and 2027 drafts.
From there... If we were to start with the low hanging fruit, and say they're going to replace the worst of the 4, then I expect they will start with Center. If they address it, rounds 3-4 range are usually the wheelhouse for that position. Slaughter is my favorite option, but not sure he'll be there for us in round 3.
The other OL logic would dictate they would bring in would be an OT to function in the swing role. Since it's a depth position they don't need to press that one too high, but the truth is the big dudes only last so long due to supply/demand, and in the event he gets pressed into action you're gonna be real glad if you took him earlier vice later.
