I think the trick is upgrading what we have at this point, not finding the perfect complimentary piece. Say, essentially replacing Refsnyder with Duvall or the like. (Duvall can also play 1B, FWIW.) Or hypothetically moving Yoshida which would allow you to take on a similar RHH bat-first player.
I disagree on the shrug though. There's some unanswered questions, but this is a good lineup when viewed through the glass-half-full lense.
Casas and Devers are two top 10 or top 15 hitters.
And while it's cherry picking, first-half Yoshida outhit them both. So that gives you a core of 3, if Yoshida trends upward, which seems reasonable.
The main right handed supplement to that core are O'Neil and Story. Both come with health question marks, but Story in particular seems like a good bet to rebound. Both were all-star types, but a return to just short of that gives you a very long 5 places in the lineup.
The three wild cards are Duran (box o chocolates), Grissom (may have an adjustment period, but a good bet to be good), and Abreu (same.)
Wong will just be Wong.
Our main utility guy may be Rafaela, Reyes, or Gonzlez, with Valdez as a bat first LHH option.
Last year to this year:
C Wong - Wong
1B Casas* - Casas (but up to speed)
2B Arroyo - Grissom
SS Hernández - Story
3B Devers* - Devers
LF Yoshida* - Yoshida or Abreu/Refsnyder
CF Duran* - Duran
RF Verdugo* - O'Neill
DH Turner - Yoshida
I'll rely on someone else to view it through the glass half-empty lense.
