His bat is in decline, and almost all of his assumed value comes from his defense. The prices being paid this offseason -- by sophisticated front offices with access to significantly more and better data than anyone here (or at FanGraphs) -- seem to evince some skepticism about the value of defense (at least to the extent valued by FanGraph's WAR calculations). There is no way that one can look at FanGraphs WAR numbers and come to Sandoval 5/$95 MM and Headley 4/$50 MM. But that's what the market of 30 sophisticated front offices (some better than others, obviously), with at least two really good front offices (Red Sox, Giants) valuing Sandoval at 5/$95 MM. At a minimum, it's interesting.
