Maybe I'm nuts, but with Desmond, Espinosa, and Kobernus in the system, Harris and Guzman under contract for another year, I'm just not sure signing a second baseman at $8m+ that Hudson is likely to get makes that much sense. If he goes much cheaper than that, I'd expect Minnesota or possibly Seattle to grab him.
As for his defense, while UZR has not been kind to him since he left Toronto, how have other measures, like +/- or PMR been (the stuff that requires a BP subscription)? do they also show a decline?
Tom - is VORP just an offense stat? WAR is both O and D.
