As far as upgrading the starting pitching goes, I think guys like Cueto, Hamels and even Kazmir are going to command too much in return to really be good for the team. However, a guy like Dillon Gee could be an interesting trade target as a back end rotation guy. 29 years old, sub 4 ERA guy who just got moved to the long rotation spot in New York. He's not terribly expensive, and isn't a FA until 2017
