I just think that it is D.D. 's job to set the roster , and Cora's job to manage the roster . I don't want Cora deciding who should be called up or who should be demoted , traded or DFA'd . I don't want D.D. deciding who should play and where in the order they should hit . The job descriptions should be well defined . When there is disconnect it leads to problems. And it doesn't look good when the manager says that a guy is not ready , and two days later he is starting.
