I always have to preface the next statement with "The FO needs to have scouts examining all of the following bargain bin options, and pick the ones that appear healthy and actually have a chance to make a comeback" or less I tend to get hammered.
Every time I look, it seems like there are more and more quality buy-low candidates for starting pitching. Johnson, Halladay, Anderson, Marcum, Johann Sanatana are all on the pile. Several guys with very good pasts -- one or two might actually turn it around.
