I think we already are looking at a .500 season - we got that when we signed Percival. We had something like 30 blown leads in the 8th inning or later last yr, so having Percy and Uggey as one of the best setup/closer tandems in baseball already bought us those 10 extra wins.
My sights are higher. If we sign Maggs and he's able to contribute immediately, I see us giving the AL Central a run for the money. Of course it all depend on injuries, but on paper, our lineup is as good as anyone and arguably much deeper. If our young pitchers develop the way they should - specifically the MR guys like Colyer, Rodney, Spurling, etc... - we can be right in the thick of things come September.
Hows that for optimism?
