I said DD did not trade any top prospects after the Sale trade. If you want to count #6 Beeks for Nate in the summer of 2018, then he did not trade any after the summer of 2018, despite not signing anyone to take Kimbrell or Kelly's spots in the pen. I see this as an indication that a change had occurred in the team's top priority, even before Bloom arrived. It is a theory.
I feel DD probably wanted to trade for a closer.
Before the deadline in 2019, he apparently came close to trading Betts & Price, so yes, I think a change occurred during DD's last year or 1.5 years. You are free to disagree.
As for the farm vs the big club trade-off, it's not clear the big club has always been the top priority. Just because you think it should be, doesn't mean it was.
Note: I'm not saying the big club was priority #2 or #3. It's hard to know what the plan was, or if the plan changed over the years. I'm just saying, I think the farm and 40 man roster depth was the first priority under Blooms first 2-3 years, and maybe all years. I also think that priority became #1 during DD's last 1 to 1.5 years with the Sox. It may or may not have been a source in the friction between him and and Kennedy/JH- whoever, that ultimately led to his leaving.
It's my opinion, and I do think some events that happened and stopped happening support my theory.
