Garland does not have the ability to win 20 games. To win 20 games you have to be consistent, and he's never shown the ability to do so in his entire career. He's got decent stuff, but doesn't have what it takes between the ears. If the RJ trade still might go through, the Sox should jump at the chance to give away Garland for either RJ or Vasquez, just so long as they don't give up too much else.
