A lot of that "restocking" was just maturation from the previous rebuild phase.
Examples:
Daniel Norris was a 2011 pick that matured in 2014
Franklin Barreto was signed in 2012, in the old international prospect process, before international bonus slots, for $2M.
Osuna signed before 2011
Castro signed in 2012
Pompey was a 2010 pick
Labourt was signed before 2011
Tinoco signed before 2012
Cordero signed before 2012
Sean Nolin was a 2010 pick
Alex Anthopoulos didn't do the Marlins and Dickey trades and then "restock" the farm system before spending a bunch of it this year. That's a myth. It's not possible to rebuild a farm system in a year or two without doing an MLB level tear down.
In fact, to build the 2015 playoff team he very much dipped into the same prospect capital that he dipped into to get Dickey and the Marlins guys. He went to the same well in 2015.
A legitimate farm system has 50+ notable prospects. In any given MLB draft + international signing period, a team is probably lucky (or has done well) to get 10 notable prospects. It takes half a decade or a string of very good drafts to rebuild a s***** system.
There's a very real chance that Anthopoulos was mis-managing the team's farm system and young talent, and it just hadn't caught up to the organization yet.
(Rogers, I need an advance on that next paycheque).
