On the other hand, City's NYL > NL progression remains the worst of any team.
While its not "progression" do you know how many of the ACFC youth players have gone on to play NL or higher with other clubs?
A fair few, though I'd say that tells you more about Auckland's size as a city and the fact that so many players play NL than them doing anything special. The ACFC NYL team has always seemed fairly separate from the ACFC NL team.
