One thing I'd like to look at, also, is consider the gap between players and what upgrades need to be made/are available to try to somewhat equalize these rosters:
QB:
Drake is already far better than Mac, so this is covered.
RB:
I'd kind of consider this a wash between 2021 and 2024, but I do think a solid receiving RB would be nice.
WR:
Hopefully Bourne in 2025 will be close to his former self in 2021.
Boutte won't be as good as Meyers in 2025 but will be better than what Agholor was giving
If you can sign Higgins then perhaps he gives you around what Meyers gave you, and Pop is an extra.
TE:
A wash IMO. 2024's group may be better since they're being utilized better, even if Jonnu is the actual better player.
OL:
LT - Lowe vs Wynn is kind of a wash? Lowe could be improved on but not easy to do.
LG - You can find a Karras-level player in free agency, or better. Trey Smith is available.
C - Andrews may return, or possibly Cole Strange will be the new center.
RG - Wash. Onwenu.
RT - Brown was very good at RT in '21, versus Jacobs not being good. But drafting/signing a decent RT shouldn't be TOO hard. Maybe Caedan Wallace can be that guy, but I'd still try to invest in the position.
So, all in all, seems like the needs to match '21 are to sign a WR (Higgins definitely does it, though there are other options), a guard and sign/draft a right tackle. At least in my opinion. Should get you a wild card caliber offense if the playcalling improves and the defense also improves (should spend heavily on defensive free agents, since as
@One-If-By-Sea said, those guys are usually more plentiful and higher quality)
