As laid out in my post, DA is pretty much just a rival league to ECNL made up mostly of non-ECNL clubs. There are some seemingly weaker ECNL clubs that decided to switch from ECNL to DA. And there were a select few that had illustrious histories with ECNL that decided to take on both DA and ECNL. But it is only in the SW region where a group of DA-only clubs seemed to believe forming the rival DA league wasn't enough to challenge ECNL so decided to try to put their B teams into a closed league. But that league is nothing like ECNL and has only hurt the top divisions of our two main local clubs (CSL and SCDSL), and conversely, the DPL teams themselves. Competitiveness has been debated by others previously. Let me just say that at the '02 level, which I'm most familiar with, there is no indication that a majority of the DPL teams would be particularly competitive in the Champions level of SCDSL. For example, - Beach FC has a winning record in DPL, but lost 1-0 to Legends FC West in the California Regional League back in August. Legends FC West, in turn, has a losing SCDSL record (currently in 8th place). - Real So Cal DPL is undefeated after its first five DPL games with a +13 goal differential, but lost 3-1 in California Regional League back in August to CSL Premier's Fullerton Rangers White. That Rangers team, in turn, tied its CRL game with CDA Slammers FC - HB G02 Elite, which is currently in 5th place of the Champions division. And so on. You get the idea. If DPL were anything close to ECNL the weakest of them should be able to crush Flight 1 and CSL Premier teams. My daughter has played against ECNL teams and the ECNL teams by and large have been at a completely different level than the Flight 1 and CSL Premier teams she's played against. That includes the former '02 So Cal Blues Holley Flight 1 team whose roster now makes up the bulk of the Blues 01/02 DA team (and which team currently has a winning record in DA ). It's great that sometimes DA coaches come and watch DPL games. But at the '02 level, I've seen ECNL head coaches (e.g., Strikers and Arsenal) that are also the full time head coaches of the ECNL Reserve teams. It's the same coach and the same system. The structure of DA/DPL makes that overlap harder, not easier, to ever pull off. And I'm delighted that your daughter is having a good experience DPL and is getting good training. But so are girls on Flight 1 teams. There are a lot of good soccer clubs outside of Southern California. If there were a compelling developmental reason for DA clubs to form secondary closed leagues others would have done it. My impression is that DPL has only been a detriment so far. But again, if there were some evidence that DPL clubs are investing MORE resources in coaching and facilities than they traditionally had invested in CSL Premier and Flight 1, then I'd be sold. Right now all I see is a new shiny logo, hidden rosters, and a disadvantageous change to scheduling.
