Players traded away from the Expos' farm system prior to moving to D.C. courtesy of Omar Minaya:
Jason Bay (2004 Rookie of the Year, All-Star in 2005, 2006, & 2009, Top 25 in MVP Voting 2005 & 2006)
Cliff Lee (2008 AL Cy Young Award, All-Star in 2008, Top 25 in MVP Voting 2008, 4th in AL Cy Young Voting 2005)
Grady Sizemore (All-Star in 2006, 2007, & 2008, Gold Glove in 2007 & 2008, Silver Slugger in 2008, Top 25 in MVP Voting 2005-2008)
Brandon Phillips (Gold Glove in 2008, Top 25 in MVP Voting 2007)
Chris Young (2007 All-Star)
... Wow, thanks a lot Omar! Remember back in 2002 and 2003 when he traded all those young players for Bartolo Colon and Cliff Floyd in some stupid run for the pennant?
Basically, Minaya mortgaged the entire future of the organization for almost a decade.
Then MLB hired Bowden and he made things significantly worse.
