Like hybrid said, you should definitely move Patterson, though his value is pretty low at the moment. He is a good pitcher, but has trouble staying healthy. Finding a guy willing to take him could be difficult, but a guy with few keepers may not have a choice. He may have better prospects - try and get one of them. If not, Miller is a potential stud. I'm not sure where he'll rank, but I'm sure we'll get a good idea of how good he is with that "September Call-Up Guarantee" in his contract.
