Just to play devils advocate, they trade him because they have had extension discussions with him and they know he’s not going to re-sign.
To me, the better question is do we want the current FO making trades like this? If the Pohlads eventually complete a sale, then it’s likely that the new ownership will bring in their own FO/coaching staff to make decisions like this. I don’t know if I want a potential lame duck FO making moves like this.
