I'm highly conflicted. Clearly, if his side says they won't sign here long term, you deal him, and I think you deal him this year. If there is a chance to realistically keep him, I try to sign him by July. If that doesn't get done, I likely deal him. This team looks very far away right now. ZERO starting pitchers in AAA that look like even number 4/5 types. Who knows about AA and health......
The big issue is their unwillingness to pay top dollar for great pitching, so Berrios might be the best they can hope for anytime soon (and, so far, their inability to develop even a decent starter). If you deal him, where does pitching come from?
