U12 = 2006 next year in the DA league. If clubs only have one DA team, the 2005's in those clubs will have to look elsewhere if they want to stay in the DA league.
135 clubs in u12, 90 in u13, 75 in u15/16.
The clubs with the 3 dev teams this year will most likely have the following in 17-18'
U12 = 2006
U13 = 2005
U14 = 2004
Full DA clubs the above plus:
U15 - 2003
U16 - 2002
U17 - 2001
U18 - 2000
Some new clubs might be added or get elevated to full DA or DEV (3 teams) status but unless things change when the apps come out next month don't expect much change in 17-18' beside the single age groups with the U15/16 & U17/18.
The new LAFC MLS club only has U12 in 16-17' what will they apply for in 17-18'? I would think for sure at least 3 dev teams and maybe full DA but will they partner with somebody such as LAUFA or Slammers again like they did with the Girls DA?
