I have already Nathan, Julio, Kolb and Graves. Wickmans been added on Yahoo, a FA in my league and Im thinking Wickman over Graves...sound right? Still crappy overall for closers but best I can do now.
i would say wickman is the worst of the bunch you mentioned. not only hasnt he pitched in a year but he has both david riske and jose jiminez to contend with. (jiminez's sinkerball has supposedly looked great now that he is out of the thin air) graves has to worry about wagner but i think he will still get a fair amount of saves.
you dont have great closers but four decent ones should be enough.
