Please read this and mentally replace the word Royals with the word Nationals.
The Nationals have made fewer developmental mistakes than the Royals I will grant you that. But in terms of leveraging their greatest asset; time, they have been just as bad if not worse.
I would add that the Royals don't have the resources the Nationals command. Even so, the Royals have paid above slot in the draft for multiple players over the past few years AND they have been active internationally. This despite the fact they gave former Nat Jose Guillen $30m+.
2011, 2012, 2013 those are the years to be aiming at.
