I do not think the Dodgers are a player now that they have signed Blake and Loretta. They have needs at 2nd and short, and they have Hu, Dewitt, and Loretta to fill them. Granted Loretta and Dewitt are basically only suited to play 2nd.
POPS
Blake and Loretta have no bearing on the SS position. The Dodgers are in the same boat as they were before signing 3B Blake and backup 2B/3B Loretta. They have Hu at SS.
