Boys ECNL either hasn't cared or hasn't had the same leverage as Girls ECNL to force the issue in the past. Even before MLS Next, Boys ECNL had a number of clubs nationwide with both DA and ECNL (although in some cases there wasn't an overlap in all age groups) and they continue to permit that currently. In the Socal/Southwest area, LA Surf, Phoenix Rising, and RSL-AZ all have both, and nationally there a bunch of top clubs with both, including Vardar, Real Colorado, PDA, Orlando City Youth, FC Delco, and Boston Bolts. That may change, but I suspect that right now Boys ECNL would rather have the additional clubs and wait to see how things shakeout with elite boys leagues over time than to cut ties with them altogether.
