Sorry, let me be more clear. The GPS girls should already be in ECNL. That league and all leagues that seek to keep kids from playing at whatever level they can are anathema to decency.
As is apparent from their actions, USAMP isn't run with that in mind and therefore votes/deals to keep children from being able to play at whatever level they can. SCUFC and CESA having girls ECNL teams has no bearing on USAMPs activities.
