What Houston shows is you need developmental "luck" and good trades.
Phillies have actually done a good job of getting talent out of trading veterans, not as much or as fast if they had started after the 2012 season, still a deep stable of young starting pitcher prospects.
Altuve is the kind of luck you need, $10K signing was no different than all those guys Sal signs, you hope you hit on a couple lottery tickets.
Houston actually didn't draft well, outside of Correa (#1-2012), Springer (#11-2011), Bregman (#2-2015). McCullers (#41-2012) and Fisher (#37-2014) they didn't hit on a lot of draft picks. Not much from rds 2-8. It was three picks in 2011-12 that set the stage for 2017. It takes time from the draft to the ring.
Kuechel was 7th rd (2009).
Nor did they sign a lot of LA players, Altuve, Feliz, Martes and Gurriel as a 32 year old Cuban
Josh Reddick, 4yr/$52M is their only "major" free agent, they traded for Verlander, but only have 2 years of exposure.
Most of this team was built on trades, which is why I don't think they're a potential dynasty, McCan (33), Gurriel (33), Aoki (35), Reddick (30), Beltran (40), Fiers (32), Morton (33), Gregerson (33), Harris (32) - while they have a solid young core, they also have a lot of age on this roster.
Lessons learned?
1) good trades, especially for other teams' prospects which they undervalue
2) get lucky, find some hidden gems (Sixto? Kilome?)
3) be patient and build the core
One advantage Phillies have is better drafting, Altherr (8th rd), Hoskins (5th rd), Kingery (2nd rd), Herrera (Rule 5), they're not dependent on just 1st rd picks in their rebuild.
