Lets talk about the players you're calling "B" level: Let take the 02's, specifically Eagles and Real So Cal '02 ECNL teams. Both clubs will not compete in ECNL after this season and both clubs roster approx. 21 players including duals. 97% of those '02 players will not make '01 DA and it's certainly not because they are "B level players." It's simple math. Hypothetically speaking, lets say, there are 18 "A" Level" '01s and 18 "A level" '02s equally skilled in their respective age groups. How many players will be rostered on one 01 DA team? Simple math.
So, whether the '02 ECNL players competed in SCDSL, CSL or the new DPL, why would you consider them "B players" Furthermore, how many "A" players are there really in this ginormous soccer landscape? Development is what's most important. I would hope all youth players and their parents, despite the players skill set, are more interested in development than a badge on their arm or a made up bracket.
Lsat but not least, isn't it ironic DPL's founding members are the same DOC's whose clubs have never been accepted into ECNL - all these years they've been screaming about "exclusivity" and yet they created the DPL - a similar two headed monster and here we are yet again, closing the open market.
