I have spoken with multiple head coaches on this topic. They simply don't care about your team or club if the player can do the business. They care about the player.
In regards to your specific list, please note that GA Southern and Wake were both at USYS GA State Cup in June 2012.
It just isn't true that all the good players are at ECNL clubs. Coaches know this and will go where they need to go to see the players they want. You can tell yourself and others the contrary, but it doesn't make it true.
