Why not name the ones you think need the biggest upgrades?
I do think we lack star power on O and could use an upgrade, but some offer great defense or low cost long term control.
This guide might help you choose:
Position by position:
C: AR's .790 is 7th best. (We 100% are not upgrading here.)
1B: Best OPS and 2nd best fWAR in Contreras
2B: Mead's .851 OPS tops any 2Bman's in MLB.
3B: Durbin's OPS was 14th among 3Bmen with 350+ PAs. He placed 9th out of 10 with 500+ PAs. Is there where you'd upgrade? His defense was amazing, and if he can hit like the 2nd half, he's be top 10-15 out of 30, but this could be a spot we try to improve on offense.
SS: On paper, this was/is the slot to upgrade. Would you trade Arias for a proven SS with offense plus-plus?
LF: I think Anthony is not viewed as a slot that needs an upgrade, but he could DH, so YES, we can upgrade over Duran/Jones/White/Campbell, and knock Yoshida/Mead and others from DH, I guess. (NOT!)
CF: Rafaela's offense could be upgrades, but he's our top fWAR guy from 2025-2026. Plus his OPS was upper tier in MLB among 2Bman (9th out of 19 w 350+)
RF: Abreu was 9th out of 18 and is a GG winner in a difficult Fenway RF. He's young and still on arbs. NOPE!
DH is the obvious slot, but even if we trade Duran, we'd have Mead, Yoshida, Gasper/Jones/Romy at DH. Dumping Duran and Story would boost the offense, even without adding from outside the system, but we could add someone, if we dumped both (plus maybe Yoshida,) but let's be real. We ain't dumping Duran, Story and Yoshida in one winter. We couldn't even dump one last winter.
Let's say we can and do: bring it on!
Sign a DH (???) and play Mead at 2B and Anthony in LF.
Sign a LF'er (Suzuki/Aroz?) and DH Anthony.
Sign a 2Bman (B Lowe?) and DH Mead.
I'm in. Then I'd wake up.
