With or without an affiliate league they will still get the best talent in the area to tryouts.
Also, the Academy is adding a younger tier next year - this year's youngest Academy teams are 2004, next year's will be 2006 -- making the affiliate league even less important.
Sure, but is it not a far better thing to have these talented youngsters playing week-in week-out at a league competition where they can be assessed and brought up within the system rather than relying on a try-out session, which everyone knows is subject to circumstance? How many players miss their big shot because they have an off day on trial? Not likely to happen to a player who is essentially having a trial every Saturday for six months a year.
Of course, if NYCFC aren't sending coaches to assess the players then that's another matter, but still better to have the resource available.
