Hard to know.
Moreland had only 79 PAs with the Sox, last year.
He's a very good defender and has hit pretty well. He is not a 1.177 OPS guy, like he was in those 79 PAs.
I've always been high on Dalbec- higher than most and perhaps too high. His K's are worrisome, but he gets on base a lot, unlike Chavis and Middy. His 92 PAs of .959 ball, last year was nice, but I'm not expecting that over a full season.
I hate to compare 2020 to 2021, since 2020 was just 60 games long and much less for several players. It might be better to look at 2019-2020 vs 2021, in some cases.
We stayed even at catcher and SS. Our 1Bman, combined, hit .942, last year, so it's hard to say we can get better, but we can do better than 2019. (Same with catcher: thanks to Plawecki, our C OPS was .865. That will not likely be repeated.)
I do expect improvement at these slots (some over 2019/some over 2020):
Position 2020/2019
2B: .586/.661 - Hard to not see massive improvement here, unless EHern plays CF
DH: .623/.776- Gotta hope we see more like 2018 or 2019 than 2020, here
LF: .683/.753- I'm confident we improve here.
3B: .816/.897- Let's hope for 2019 not 2020, but I'm hoping even better.
SS:.824/.943- Bogey is in peak prime, now.
RF: .853/.926- We can't beat Betts and 2019, but Verdugo can improve.
Others:
C: .865/.744- Just give us neat .790, and I'll be happy.
1B: 942/.745- Hard to call. somewhere in between would be nice (.800+)
