I found this in the comments on MLBTR during their monthly Brob-to-Cubs post:
The Orioles get a solid 1B in Lee to keep their offense churning from the previous season, as well as a solid young 4/5 lefty to slot into hte rotation. On top of that they get a great pure hitting prospect in Vitters, a potential lockdown closer, a potential quality replacement for Roberts and a good OF prospect. The Orioles would have a good offensive core with Markakis, Jones, Wieters, Rowell, Vitters, Snyder, Thomas, Colvin and Reimold.
The obvious Cubs fan got wood over the lineup they would get. I could go for Lee, although he ain't cheap, $13M until 2010. Marshall needs work, and the others are all highly touted A to AA prospects that might be ready in 2-3 years. We would need to find a whole middle infield and a DH. Good idea? Bad idea?
