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. But have the Cubs even mentioned that they might try DeRosa @ SS? I've been wondering why I keep hearing it every once in awhile on nsbb. The Cubs had ample opportunity to try Mark out @ SS last year, yet he played 1 game at the position. The Cubs didn't exactly have a second baseman last year either to plug in if DeRosa was there for most of the year either. The Cubs do value Theriot's defense at short over DeRosa's, we know that (otherwise they would have played DeRosa at SS and Theriot at 2nd). Do they hate DeRosa's defense enough to know if they would play Theriot there even when the other one would sit on the bench? I don't think anybody knows that, and what we do know is that Lou is willing to try almost anything if the starter is struggling. Lou was willing to play Ward in RF in small ballparks because he needed more offense. If Theriot is struggling and DeRosa is just sitting there on the bench, Lou might go to him. That all falls under the cateory of "highly speculative" in terms of what would actually happen. Which means planning out any proposed trades or other moves based on a DeRosa move to SS is also highly dubious.
