Of those guys, I guess Kiermaier could be ok if you are only giving up a B level prospect. Cain, Fowler, Heyward and Myers aren't really CFers anymore and I want to keep Verdugo in RF.
Inciarte is a weird one for me. Offensively, his contact rate has taken a nose dive the past two years. Same with his defense. I don't see the appeal.
I don't know what to think about Kingery. Seems to be more of a super utility guy than someone you just slot in for CF. There was a lot of hype for him a few years ago, but he really floundered in 2020. His contract isn't really a killer though and he has the highest upside of any of the guys you mentioned.
