And don't forget that Giolito, along with the guy after Kieboom, Dunning, got us Adam Eaton, who had his injury struggles in Washington but still is a .288/.377/.425 hitter here and had a pretty good World Series performance.
Since (A) the Nats just beat them and (B) everyone praises their analytical approach, for comparison below are the Astros first round picks over the same period, though I'm not sure when Houston truly began their "modern" approach. They went to the World Series in 2005 and their stretch of last place 100-loss seasons was 2011-13.
2005 (34) - Brian Bogusevic
2005 (38) - Eli Iorg
2006 (23) - Maxwell Sapp
2007 - no pick
2008 (10) - Jason Castro
2008 (38) - Jordan Lyles
2009 (21) - Jiovanni Mier
2010 (8 ) - Delino DeShields
2010 (19) - Mike Foltynewicz
2010 (33) - Mike Kvasnicka
2011 (11) - George Springer
2012 (1) - Carlos Correa
2012 (41) - Lance McCullers Jr.
2013 (1) - Mark Appel
2014 (1) - Brady Aiken - did not sign
2014 (37) - Derek Fisher
2015 (2) - Alex Bregman
2016 (17) - Forrest Whitley
2017 (15) - J.B. Bukauskas
2018 (28) - Seth Beer
2019 (32) - Korey Lee
Eli Iorg (2005-09, highest level AAA), Maxwell Sapp (2006-08, A), Jiovanni Mier (2009-18, AAA), Mike Kvasnicka (2010-15, AA) and Mark Appel (2013-17, AAA, traded to Phillies in the 2015 Ken Giles trade) never made it to the Major League. Bukauskas and Beer were part of the package sent to the Diamondbacks for Zach Greinke.
So they had some stand-out picks, but also quite a few busts.
