I don't think any GM, in their right mind, trades a good young controllable pitcher for Casas, unless the team is cheap and the pitchers is about to begin his first or second of 4 arbs.
No, I have nobody in mind.
If we decide to move Devers to 1B and extend him, I'd think about trading Casas. Right now, I'm thinking of keeping all our best prospects and maybe making trades to get more.
