He's no longer part of the Sox long term plans, IMO. He's going to hit the FA market regardless, given that Boras is his agent. The Sox need to prepare for 2020 without him. They can stretch him out in 2021 if they want to, but for 2020 they need to have that spot occupied by a competent, semi durable starter. Maybe they can give him starts when they have to shut down Kopech toward the end of the season, but they should work him for longer stints out of the bullpen to start, until he needs to replace either Kopech or Cease.
