During the mid-2000s, Fox utilized active or former players and managers as "guest analysts" on the network's League Championship Series telecasts. These included Bret Boone (2003 ALCS), Al Leiter (2003 NLCS and 2004 ALCS), Brenly (2004 and 2005 NLCS), Lou Piniella (2005 and 2006 ALCS), and Luis Gonzalez (2006 NLCS). Many fans accuse Fox of choosing announcers biased towards large market teams, citing some of these choices, including Boone, whose brother, Aaron Boone, was playing for the Yankees in the 2003 ALCS games covered by Bret Boone.
