Those high picks did help, but they also had their share of hic-ups in drafting, including losing several picks over the cheating incident and picking Mark Appel & Brady Aiken with two of the 4 straight number one picks they had from 2012-2015. No doubt these first round picks nailed it:
2011 Springer 11th
2012 Correa 1st
2015 Bregman 1st
2016 Tucker 5th
They also traded for Yordan Alvarez before he even played one game in the minors. IFAs include Altuve, Framber Valdez, Luis Garcia and Urguidy. Javier was a minor league FA signing in 2015. Hunter Brown a 5th round pick in '19, and Jeremy Pena a 3rd round pick in '18.
The current Astros GM, James Click, who became their GM in 2020 got his first MLB job with the Rays thanks to a recommendation from Chaim Bloom. He has made some key moves, but much of what the Astros have now was inherited.
Bloom inherited a much different team, farm and system.
