Jackson has atleast shown some poise on the mound, to prove he deserves a chance at a spot. My guess is that that Sheets, Capuano, Bush, Villaneuva, Vargas will be the starting 5 as of right now, but that can change in spring training. My personal opinion is that we should go after an arm in the pen instead, because the rotation because the FA options are not as good as what we got.
