WOW!
To be clear, the pyramid explains "INDIVIDUAL PLAYER PATHWAYS" @ LA Premier. And is used to educate parents on the levels a player may be placed into if they have interest in the LA Premier Program. Nothing to do with any other club or a statement on other league levels. However, LA Premier believes DA will be the highest level of play in the country.
Here is the verbiage that accompanies the pyramid... pretty simple stuff.
"These pyramids represent an insight into how our DA staff process initial requests to join our Academy structure and are designed to be a guideline to the selection process and not a rule.
Exceptions are made for players that possess a Defining Quality that the coach believes the squad is in need of, at any specific age group. More information can be sought by discussing your child directly with a member of our LA Premier Academy Staff. "
LA Premier doesn't have ECNL, some clubs have both DA and ECNL.
EACH Clubs pyramid may be different...
There are a few more graphics on the same page, with more information that clearly defines ECNL as a prominent National League.
