I would say a good development system has a player exceed their value. But yeah it is kind of objective and they do have a new team so they may not be bad. My apologies for overstating a gut feeling as a fact.What makes the Wizards a bad development team? Most of their picks have retained good value (outside of Johnny).
I'm pretty high on the Wizards future of being a competent team. They got new management and they are objectively making the right moves after previous management put them in a really bad position.
