For what it's worth, I felt much worse about our rotation in March 2021.
Here's my early take...
Eovaldi: The guy has become a horse, when his history was almost the opposite until maybe 2020. There is no reason to think he will decline, significantly or get injured. I'd expect close to what we saw in 2021.
Sale: I'm optimistic, here. I'm expecting 160-170+ IP, so that alone, could be a big boost, even if he doesn't come to close to the "old Sale." I do think this guys is a fierce competitor, and if that means anything, he could come close to his prior form.
Pivetta: I've been a big believer in this guy. He has some nasty stuff. He's had some ups and downs, but he seemed to come into his own, overall. He still has a serious issue with BBs, and his 3.8 BB/9 was higher than his career 3.5 mark. (9.8 BB% vs 9.0% career) Gotta like his ERA+ with the Sox in 165 IP from 2020-2021.
Paxton: I'm setting my sights on 2022 for him. Anything we get from him, late in the season, might be icing on the cake (or lipstick on a pig.)
Wacha: I'm not impressed, but apparently he showed signs of turning things around, late in the season. I'm thinking things often turn both ways. I'm trying to be hopeful but finding it hard, here.
Hill: This guy can pitch. He may pitch until he's 50. With him, it has been and always will be about his health. Here are his IP over the last 5 years:
136 (2017) 125 ERA+
132 (2018) 106
59 (2019) 169
39 (2020) 143
159 (2021) 103
Others: Whitlock, Houck, Winckowski, Seabold- lots of promise here.
