I'd like to hold onto Marshall as well, but if Wood and Prior come back healthy, we have the following pitchers: Zambrano, Maddux, Wood, Prior, Rusch, Marshall,Guzman, and Williams. If Miller returns healthy, that makes nine possible starters. It's from that depth the Cubs could add a bat. It's doubtful a contender is moving an impact bat. That means those teams are going to want a player for beyond this season. Guzman and Marshall make the most sense. I understand the idea to look toward next season's rotation. Zambrano and Prior will certainly be in the mix. The Cubs could pick up Wood's option, but if they let him walk they will also have 10-13 million to spend on a FA. The same is true with Maddux. If he walks, nine million is freed up for an acquisition. Having twenty million to spend on FA pitchers should be adequate to add two nice arms to the rotation if the Cubs had to or desired to go in that direction. Rusch will also be under team control if needed for depth. Williams, Hill, Marshall, and Guzman could also be options. Ryu should be ready to start at the major league level as well. So even with Maddux, Wood, and Miller not part of the 2007 picture, the Cubs have the depth to trade Marshall if the player they acquire is an impact player. At this point, it's hard to know who that will be.
