JD is fine in the OF defensively because his offense more than makes up for his shortcomings defensively, sort of the opposite of JBJ, (although JBJ is starting to come on offensively). Of course any team would take JD.
JD does not make any glaring mistakes in the outfield, which makes it seem like he is doing just fine out there. However, to date, he has been below average defensively. FACT
