With Masa still on the squad, it wasn't a perfect fit for the next few years. JD was still valuable enough that you could have spun him in a trade prior to '22 and fit Schwarber just fine. Or just faked Schwarber for a year at 1B before letting him DH for 23-25. Once he signed with DD in PHI, I don't think he was ever going to come back to BOS. It would have been cool, but not an option I took seriously.
