If its true, I don't follow the rationale on the boys side for the MLS teams. With the opening up of training fees when selling on players, boys DA could be a lucrative revenue stream, plus developing your own players is cheaper than having to buy. They (MLS) also need a funnel system or at least a development system which has a high level of play to help them scout. For US Soccer to abandon DA on the boys side … well they might as well just resign on mass as they are clearly giving up on any long term plan for the USMNT.
As far as GDA vs ECNL, there was never that much wrong with ECNL that US Soccer couldn't have worked with ECNL to resolve IMV. Their heavy handed approach was stupid from the start. Assuming GDA goes away, we'll end up with a worse situation than before as both have become watered down and now you'll have clubs out of GDA, but better than most ECNL teams, looking in. On the bright side the 4 day mandatory, no HS and play time restrictions go away … my biggest complaints on GDA.
IMV, ECNL would be best served to take the moral high road, take all the GDA teams, but split into 2 divisions, with clear promotion/relegation for teams (not clubs), and also with clear criteria for clubs to retain status. The top divisions would have the best teams (not clubs) from ECNL/GDA and ditto for the second. That would solve the 2-team clubs also. Very unlikely it'll ever happen though I'd imagine.
