Here is my view. First, I don't think you understand the absurdity of your statement. I'm not attacking you, but the concept is akin to stating ... "it seams a number of Bloods are exiting the gang and moving to the Crip's JUNIOR/PRESCHOOL gang." The idea that a Club would exit the ECNL and move to the DPL is silly. If true (highly unlikely) the DOC/Admin group is lead by fools that fundamentally don't understand that the DPL simply allows the Girls DA teams to bring in more dollars by putting out a carrot of "someday your DPL daughter could make our Girls DA team." The DPL is a "B" league for the DA, just like the EGSL is the "B" league for ECNL teams (in the region).
Now, you might have a dual Girls DA and ECNL program that drops their ECNL team for the DPL, but that isn't the same as what you wrote. No Club Admin in their right mind would drop the ECNL (competes at the same level as the Girls DA) and move to a regional junior league (unless they were in a serious auto accident and suffered debilitating head trauma).
