Yes, before we got Mayer, most would have viewed the Sox rise in the rankings, yes, we were rising in the ranking before the draft, as being depth- orientated.
It's not like Casas and Downs were lighting the world on fire and lifting our ranking on their shoulders. Far from it.
Bloom used last year's trade deadline, the Betts & Beni trade, IFA and the rule 5 draft to build some serious depth. The Beni trade, alone netted us 5 players, only one of which was not technically a prospect (Cordero). Now, Whitlock, Houck and Duran have or will graduate soon, so maybe we'll see a slight dip inn the rankings, but that Whitlock move was pure genius. I still count that as building farm depth, even though rule 5 players, by definition, are no longer on the farm.
Many of the additions Bloom made have not done all that well this year, and some have fallen in the rankings, but look at this list and tell me it's top heavy. Just because you have a super player at the top, it shouldn't devalue the rest of the farm.
Here is the youth Bloom has added, besides Whitlock, Verdugo and Arauz:
Downs
Seabold
Yorke
Jordan
Winckowski
Wong
Ro. Hernandez C
Miguel Bleis
Nathan Hickey
Tyler McDonough
Eduard Bazardo
Jeisson Rosario
Hudson Potts
Shane Drohan
Victor Santoz
Freddy Valdez
Grant Gambrell
and several others
