I would like this to become a 3-team deal.
Yankees: Kluber
Padres: Gray, prospect
Indians: 3-4 prospects
Yankees have been adamant about getting top prospects back for Gray as they should be. But they can shift gears to alter this if they are getting Kluber back instead. Attach a top prospect or two to Gray and let the Padres use those prospects coupled with their prospects to go to Cleveland.
Maybe Andujar becomes involved, but that is only IF the Yankees have signed Machado. Andujar and Gray to the Padres. Padres use their top prospects to go to CLE.
