AA drafted or acquired via trade 5 of the 8 players you listed. Most of the players listed above wouldn't have contributed much in 2013 and 2014. So, given the state of the team at the time of the trades, they would've likely been expected to lose between 90-100 games in 2013. Losing that many games in 2013 would've likely given them a top 5 pick in 2014 and possibly another top pick after the 2014 season which may not have been much better.
I think we can see that the team was being rebuilt relatively well. The big thing is, why change course and go "all-in" after 2012?
AA must bear full responsibility for negotiating the Marlins and Mets trades. I am, however, leery of the way this franchise is run from the very top to the point of suspecting the change of direction coming from the top in an attempt to avoid a huge drop in attendance and tv ratings.
Even during this past off season, why not just make the management changes and get it over with? Instead, ownership fumbled the Duquette courtship and ended up with a lame-duck F/O which must see clearly that it is not wanted long term.
Anyway, it's early...
