The best part about this is that replacing Inciarte with Miller makes Arizona worse. Pushing two of De La Rosa, Anderson, and Godley out of the rotation to make room for Miller is probably less than a 1-win boost, while removing Inciarte and his 6 fWAR over the last two years leaves them replacement-level in a corner OF spot with no CF backup. Also they lose two years of control. And an elite prospect. And another top-50 prospect.
This trade is hilarious.
