Mid 6th used to be the going rate for a future 1st and it was easy to swap. That's pretty hard to pull off now.

figure that’s roughly Judkins, k Johnson or golden range if rookies are included. So future first for essentially a late first round pick. Could see either side, depending on your plan and confidence.
In 1qb all of those guys are gone via FFPC ADP. Next rookies available mid 6th are Skattebo and Tuten.
SF is a little better because you get into the Kaleb/Egbuka range in the mid 6th, but of course the 2026 1st is more valuable in that format too.
Regardless, the point was more how rookie picks increase in value by consensus every year. A few years ago you could offer your 6th rounder for a future 1st to anyone in the league and they would take it. Now you've usually gotta giver your 5th + a little sweetener and only 1 or 2 guys willing to do it (better hope someone didn't beat them to it). I bet by next year there are some people offering their 4th for a future 1st and a few years after that, a 4th is the consensus.
It's been a pretty linear progression towards future picks having more value every year for a long time now. 15 years ago the consensus thought was that taking a rookie Adrian Peterson (best RB prospect of most of our FF lives) in the 3rd round of a startup drafts was insane because why use a 3rd round pick on a guy that had never stepped onto an NFL field when you could have a reliable proven veteran like 27 year old Rudi Johnson at that pick instead. How far we've come.
ETA: And remember, a decade or so ago there was a post on this very forum arguing that no player is worth four 1st round picks, and that was a controversial opinion at the time. That is to say that at the time buying a top player for 4 1sts was considered incredibly cheap, and people asserting against that were a minority.
