I think some people are taking wanting antoher pitcher the wrong way. Sure, Marshall, Gallagher, Hart, etc. are all capable of being slotted in the rotation. The problem is not all those guys can be slotted in the rotation, because 4 spots are taken by Zambrano, Lilly, Hill, Marquis. It basically becomes a preference of sitting 3-4 guys down in AAA, when you can trade 1-2 of them and improve your major league team. The Cubs have several prospects, although not great, who are ready to be on a 25-man roster somewhere. Why not trade some of that depth, that won't have a spot on the Cubs veteran laden roster anyway?
