I disagree about Maddux. As a pitcher who relies almost entirely on pitching strategy rather than 'stuff', there really isn't anything for him to turn on. I'm sure he takes the same philosophy out to the mound now that he did in Atlanta ten years ago, but his fastball is simply much more hittable than it used to be and he's being hit harder now than at any point in his career. He still has the control to get it over the plate (a consistant BB rate with respect to his career), but his pitches don't have the late movement they once did.
Annnnnd... I don't think he'd waive his no trade clause to pitch here anyway
Rumor has it he turned down a chance to go back to Atlanta, so I'm thinking Maddux is done and just wants to wrap the year in Chicago before calling it a day.
