In hockey it's definitely more scouting, especially since you don't even get to actively develop most of the guys you draft for very long. I dont think anyone blames the Phantoms staff for failing to bring some of these guys to fruition. In theory Hakstol was supposed to nurture a young core but he was also expected to win with the old core.
Nolan Patrick is definitely Mickey Moniak though, except Patrick actually was considered a no-brainer top 2 pick at the time, not one just one guy in a weak Top 8.
The thing is the Flyers used to be pretty good at drafting, and over multiple eras and often with late picks (unlike the Phillies who only got good at it for that one notable stretch by also picking really high).
