The Royals have been a dictatorship for years. After being a complete laughingstock of an organization, they needed a strong executive to right the ship, and they found Dayton Moore in 2006 and vested him the power he needed to clean up this organization. His work culminated in two pennants and a title, and he was a benevolent king, doing right by people, showing loyalty, and enriching the community.
The major weakness with dictatorships is once the dictator is not making good decisions, the whole thing goes to pot. Dayton Moore was unwilling on unable to adapt to modern baseball.
