players like J-Up dont come up for trade often so you gotta pony up. And yes he's the type of player that murders the ball so it'd have the be Teheran and Bethancourt together plus more to even get the D-Backs to stay on the line.
But I doubt the D-backs will deal him regardless. They have zero reason to move him. Only way I can see him being moved is if he's fallen out of grace with the team.
