Can't see how much it helped last year except for the game in NJ against the RedBull 2, but here it is... http://www.wilmingtonhammerheads.com/hammerheads-announce-mls-affiliation-2/
I think this year you may be getting more players from NYCFC. Harrison (1 pick form the superdraft) I think is going to play mostly with your team as he needs to rehab and I don't see him playing much with the first team. Same can be said for Brandt, Tony Taylor and a few other players so you may see more out of this partnership then last year.
Keep in mind that the Hammers got Fran Martinez and Andre Rawls through their connection with NYCFC last year. But I certainly wouldn't mind more this year. Like DanGerman I would expect more this year simply because they've been on the ground longer as an organization.
