I'd like to think CB. It is a must-have position in today's pass-happy NFL, and if we lose Jalen Ramsey, the Rams' CBs would appear to my eye to be among the weakest in the league (although who knows how some of the already drafted youngsters might step up).
IMO, the ideal scenario if we trade Ramsey is to get a high enough draft pick in return to secure his immediate replacement - a player that can lock down opposing WRs right away, but provide much more longevity being years younger, and importantly, will be playing on a rookie contract for years to come.
Patrick Surtain II was taken 9th overall by Denver in 2021. He was the 2nd CB selected that year. If the Rams would be picking 10th overall, hopefully they could land a similarly skilled CB. I do not follow the draft too closely. Draft enthusiasts would know better than me if such a player might be available this year. I do not believe there is a consensus top order for this years CBs, however, which at times can spell trouble i.e. crapshoot if you are giving up a player of Ramsey's caliber to roll that dice.
The draft is never a sure thing. You have to hit on the draft pick. Ramsey is a sure thing at a must-have position. He is easily a top 3 CB in the NFL IMO and defends the run - very physically I might add! - as effectively as he does the pass. For that reason, I'd prefer to hang onto him, as I do think this core can contend for another year or so. But due to the aforementioned, Ramsey he should have huge value if the Rams do look to move him. The Rams had to give up two 1st round picks and a 4th round pick to acquire Ramsey - he was younger and cheaper then, but on the other hand, market value via trade appears to have gone up significantly in recent years, as many teams "go all in" following the Rams' Super Bowl template. So the return on Ramsey should be significant.
It sucks to say it but Baltimore actually seems a good fit for Ramsey. That team's defence always seems to be very physical with lots of swagger and mean bad asses who are elite players at their respective positions. Ramsey fits the prototype. He's from the east coast I think, although at least as per the press clips, he has really enjoyed L.A.
