Rendon would be the answer at second, but we might have a problem on the left side of the infield, way too many ground balls passed in between Zimmm and Desi. If we can add an outfielder with range and a bat we might have the best OF in the league. Obviously we need a starter, although I wouldn't be too upset if we went back to Lannan as our #5 for one more year. HRod coming back might be the equivalent of a free agent signing, like LaRoche and Werth this year, that plus Garcia gives me confidence in the pen as is.
I think Rizzo will bring in a guy like Madson to do the same thing he tried to do with Lidge. While I think it'd be interesting to bring Bourn in we have Goodwin coming up in the minors and Eury/Harper can serve as a stop gap until Goodwin is ready. Rizzo like power pitchers he's not gonna want a soft tossing lefty in his rotation he should that this year when he picked up Jackson and how long he hung onto Wang.
