Truth be told, Schuerholz was not the reason the Royals were good. They were good well before he arrived in 1981 with 4 division titles under managers like Jack McKeon, Whitey Herzog and Jim Frey. Kudos to him for hiring Dick Howser, but he also had some pretty boneheaded moves like doling out wheelbarrows of cash for Mark Davis and turning the team over to managerial mediocrities Mike Ferraro and Billy Gardner.
His Atlanta success is likewise largely attributable to other people who laid the groundwork for him like Bobby Cox, Paul Snyder and Bill Clark. They are the ones who were entirely responsible for their tremendous farm system during the 90s.
