Before the days of HDH and an impenetrable Royals bullpen that would carry them to back-to-back World Series’, there was Greg Holland. From 2011-2013, the Royals bullpen was worth 15.7 fWAR and Holland was worth 46% of that total. During that span, Holland was more valuable than every reliever in baseball not named Craig Kimbrel and made that Royals bullpen the best in baseball virtually on his own. He was similarly dominant in 2014, and this time with the help of prime Herrera and newly-developed cyborg Wade Davis, Kansas City formed arguably the most dominant three-headed reliever monster baseball had ever seen.
