I totally agree with everything but the last sentence, although to some extent we do have to "sell high" like the Rays do, but just not to that extent.
I've said all along, we need to find the best scouts and talent developers and spotters, or at least top 5.
There is no evidence we have anywhere near that, now. What we did from 2003-2012 is behind us. We've had a pretty bad record drafting and signing IFAs since about 2012. I know the system has changed, but other winning teams find ways, and with the Yanks and Dodgers, it was by selling some top assets for prospects here and there.
It's time to trade JD & JBJ, try to hope others like Eovaldi, Price, Sale and Barnes build up value to either help us rebuild or to become future trade assets to further our rebuilding efforts. None of that will matter, if we can't score some top prospects through the draft and IFA market.
