I doubt that the Cubs will start DeRosa at SS. More than likely, DeRosa goes into the supersub role. He would be a huge upgrade to the bench, while Roberts would be a small upgrade at 2B, but given the rumors, it will cost us Cedeno. With the emergence of Geovany Soto, the signing of Fukudome, and the apparent determination that Pie will be the CF, Theriot at SS is the Cubs' worst position. Therefore, it's the place the Cubs should seek to upgrade, internally or externally -- whatever is possible. Now, if getting Roberts means that DeRosa plays SS (again, I doubt it), that would be good. Otherwise, let Cedeno and Theriot compete or acquire a SS. One of Greene, Peralta, Wilson, or Lopez could be available. The key here is upgrading from last season's production at SS.
