I think they do, and are actually pretty good at building up a formidable 40 man roster and farm on a restricted budget.
Brez has made some major gambles that did not pay off- most notably the Sale trade and Buehler signing, but he's done a lot of savvy moves. (To me, the Priester deal is still pending.)
I was very bummed, last winter when "all we did" was sign Chapman & Wilson for the pen, yet our pen was a major part of us making the playoffs. The Crochet deal and extension looks to outshine the Sale deal and more so with the extension part. Locking up 4 kids, long term is something we haven't seen much of, and I'm glad we joined that line of thinking.
Brez has almost totally remade the roster and farm in just a couple short years. There are only 13 players on the 40 man roster that were on it, when Bloom left. (Yes, some were in the system, but still- many more of those 27 were added by Brez.)
7 of the top 10 prospects are Brez adds.
11 of the top 20 are, too. I'd put Watson, Delzine, Ramos & Rivas above Cespedes, Bleis and Castro, making my top 21 with 14 Brez prospects.
It's been a stunning turnover without calling it a rebuild.
