Biggest team needs (offseason FA signings and NFL draft)

What do you think our biggest team needs are for 2025? I had seen a rumor we may sign Darnold to a long term deal and trade JJ McCarthy. With the limited amount of picks we have in this upcoming draft i started thinking if trading JJ would be worth it, what could we get for him, and what position groups need to be upgraded or filled for 2025. Everything I’m reading says the QB draft class is below average, so we may be able to get something decent back for JJ, and if so what are our biggest needs?
