The reality is nothing about the Phillies changed in 2015. Monty only stepped aside due to his illness, Gillick was no longer a progressive or transformational figure, and both of them were fully in support of hiring MacPhail, who was both unsuited for (and seemingly uninterested in) running a baseball operations department in need of change but also picked a protege who looked good on paper (young, analytics-minded) but turned out to be unsuited for both aspects of his job (new ideas and traditional GM stuff) as well (especially since MacPhail actually let him run the team, unlike the current structure). Once the rake hit Middleton in the face a couple of times he began to be hands-on, which wasn't always ideal either, but it led to all the changes that finally got us to the present-day.
Still gonna be a challenge to sustain success for five-six years (rather than the next two-three) given the failure to reap much from the period between trading Hamels until drafting Haseley but money and much better people certainly will help!
It's ironic that Fuld is the only real survivor/asset from that era. And I guess Velandia from the Amaro era.
