DD has a pitching staff that needs improvement externally. He has a logjam of mediocre pitchers and rookies. He probably needs to give one of the rookies a path to the rotation and the others will be depth. If he adds two top of the rotation pitchers, he has a game of musical chairs with the mediocre choices and Buch: he will have Miley, Porcello, Kelly, and Buchholz vying for 2 rotation spots. He can probably move Kelly to the pen where he can also be a depth option. Porcello has an albatross of a contract, so he will be very difficult to move. I think he will be in the 2016 rotation. It will come down to Miley and Buch. Neither is a bullpen pitcher. One needs to go. It will come down to which one is the more tradeable commodity. Will it be Miley with a reasonable size contract for a reliable 200 innings and a 4+ ERA or Buch with a reasonable salary who can be outstanding for half season stretches? They need to pick up his option for additional flexibility in moving forward. My bet is that no one will offer much talent for a guy with a bad elbow until he proves that he is healthy. He will not be able to establish that he is healthy until Spring Training. Most teams have their pitching settled by then. My bet is that DD doesn't wait until Spring Training and trades Miley in the offseason.
