I wouldn't trade him for Edward Cabrera, unless quite a bit more was coming back. I can't today slot Cabrera above Ryan or Ober, so that wouldn't work for me. He MIGHT get to his ceiling some day, but he isn't close yet.
Gilbert I could see, but I don't know how much more we would have to add. I'd be open to that.
Peralta I really like quite a lot, but even with the team control, his career high in innings came last year and that was 165. He threw 144 one other time, and other than that hasn't been over 80. If they believe he has the ability to push 180 innings per year or more, then I might go that route too.
I LOVE Arozarena, that thought is interesting.
How about someone like Framber Valdez? I don't know why Arizona would do it, but Zac Gallen is a name I've loved for years too.
