Trading back is such a balancing act. I've been wondering if the best "bang for your buck" move would be to trade back, far enough to get a 2nd. Then package that 2nd and one of the 2025 2nds + more if needed, to get back to the end of the 1st.
I really like the thought of pairing a WR with Caleb on his rookie deal. And with any of the top WRs at 9, you potentially run into a "not enough footballs to go around" scenario with DJ, Allen, the rookie, Kmet, and a pass catching RB. A later WR would allow you to bring a lesser (but still very) talented player along slowly or in a specialized role, if needed.
And I also hate the thought of the DL if you draft a WR at 9 and have no picks until 75 where you aren't getting a starting caliber player. So, the balance if you trade back is how far can you go to still get one of the top DL players (Verse, Latu, Newton, Murphy, Chop).
Trading back up, especially with KC and SF at the end of Round 1 also probably works because they don't have a ton of needs being the best 2 teams, and SF in particular really loves future draft capital. But it also gets you ahead of Carolina at 33, who is almost certainly going WR.
Caleb, Verse, and Worthy would be quite the haul early and then they can go after OL and DL depth with any later picks they have.
