Unfortunately your statement has little merit. I would agree that top to bottom ECNL has the the edge by a decent amount but to say "ECNL would wax all of the teams" is simply a stretch. Beach FC's '02 Academy tied Slammers ECNL 1-1 at the Thanksgiving College Showcase. My DD and I watched the game because our neighbors DD plays for the Slammers ECNL team (currently sit in 2nd place in the SW region). Both teams were only missing 1 player.ECNL would wax all of the teams. They could play their bench and beat almost all of them.
The youngers landscape has changed a lot since your DD played, I'm sure you can at least agree with that much.
