Isn't that counterintuitive, though? Perennial Cup contenders will be drafting near the end of the rounds and often are trading away their picks to load up for the playoffs. On one hand, they have more of a justification for keeping prospects on their affiliates longer, but could it also be that they are more likely to get the tweeners who star in the AHL but wouldn't get more than bottom line/pairing minutes in the NHL?
I think it is in part a reflection of drafting, developing and signing well tbh.
As:
1. Top talent rarely spends much time in the AHL.
2. The time from drafting your top talent to competing is usually like ~4-6 years.
3. Depth players who are good NHL depth guys are usually great AHL players... so having 4-5 such players on an AHL team usually elevates them to AHL contenders.
4. Younger guys doing well in AHL/able to play NHL can also be used as add-ins in trades to improve team.
5. Those guys they keep then a few years down the line can slot in on NHL team.
But yeh, I also think top to bottom good management means that a FO is also able to build a good AHL team alongside starting to get NHL team ready to win.
For example take Tampa... they had their AHL constantly be good, and lost in AHL finals in 2013 and 2017.
2013 team had: Johnson, Palat, Killorn
But also had Connolly, Namestnikov, Gudas, Brown, Panik, Sustr
2017 team had: Gourde, Erne, Cirelli, Stephens
and a few other guys who became NHLers on other teams.
None ever became real "right at the top of a line-up" guys... but were all on deals signed before age 27 when they won first cup.
