Some points:
1) the recent "success" was all due to trades, once those players graduated (Pivetta, Eflin, Velasquez, Arano, etc.) there was a big hole at the top of the farm system. The rot has been in place for a decade.
2011: Quinn #66, Morgan #120, Rios 12th rd
2012: Anderson 21st rd
2013: Crawford #16, Knapp #53,
2014: Nola #7, Hoskins #142, Davis 12th rd
2015: Kingery #48 [Falter, Leftwich, Gilbert best prospects left]
2016: too early to tell, Moniak, Gowdy, Irvin, Dyer probably best shots at ML career
2017: Haseley, Howard, Seabold, Warren, Dohy, Jones
2) Klentak has made significant changes the last couple years, 2 GCL teams, hiring additional coaches, a new emphasis on video and analytics, but this shift in organizational philosophy takes years to implement and probably won't pay off for a couple seasons.
3) LA is complicated b/c of the Venezuela situation, Phillies are one of the few teams still active there, and to credit them, it seems to be as much about taking care of their own as striving for a competitive advantage (every dollar you can funnel to your people may be the difference between eating and starvation).
Players are starting to turn it around on the farm after a really shaky start up and down the organization.
Because so many players got off to slow starts, it makes you wonder if they've been making a lot of changes, and players are struggling to adjust.
