I would disagree- we have Celestino already on the 40 man, raking at AAA. Where does he fit? Then you have Royce Lewis and Austin Martin, who will be MLB ready in 2022 and both play SS and CF. Then there's Nick Gordon, also on the 40 man, who also plays 2B, CF, and played SS in the minors but hasn't in MLB.
Honestly, trading Polo at his peak or trading Arraez, who doesn't really have a position, seem possible.
