That two year period 2017 and 2018 set them back a fair amount. Wasted money on Bautista, Morales. Botched the Donaldson thing. Made some bad trades like bringing in Grichuk, trading Edward Olivarez, screwed up the Happ return, lost Berti (useful player) for nothing, traded Urshela for nothing, in hindsight didn't get much for Osuna or Seung-hwan Oh or Aaron Loup...
They did a couple good things like land Espinal and Teoscar and sign Gurriel but for the most part their execution and decision making sucked for two years.
I guess to be fair it's almost to be expected when you take over an organization. Your systems and decision making channels will not be as fine tuned.
