Given the QO process, I don’t see that as necessary. The draft pick loss only applies to QO'ed FAs, and a player can only be QO'ed once. So if a player is QO'ed this fall, after a non-season or mini-season, the obvious strategy is to accept the offer, take the guaranteed salary, and go FA again after 2021, with no QO.
The complication here is the pending change to the CBA after 2021. But I’m not convinced there won’t be a fairly quick settlement of that; the 2020 season is already partially lost, and not withstanding optimistic hopes about “reopening,” more of the season is at risk if premature “opening” leads to a midsummer surge in CV-19 cases. Does MLB really want to risk losing the 2022 season as well?
