In the 2021/22 season there was a sanctioned 2nd tier MLS league in the Northeast. https://www.mlssoccer.com/news/mls-next-creates-strategic-relationship-with-northeast-academy-league. This league was operated by USYS like CalNorth is today. Most of those clubs in that NE League are now committed to the National Academy League. Maybe CalNorth did not have MLS support for the branding/naming. Seems inevitable that the NAL will have some sort of MLS agreement and that’s where most MLS clubs with have tier 2 teams.
Do you know if the NAL is shaping up to be a closed or open circuit? Meaning can non-MLS Next Clubs compete in the NAL or is it only MLS Next second teams and pre MLS youngers teams? If the former, it's just a replacement for the EA...especially since the academy teams (excluding affiliates like LAFC or Houston) have decided they pretty much don't want to get into the administration of anything outside their academies. If it's the latter, it would seem to insulate the 2nd teams from those rogue upstarts that can put their best players into the 1st teams because they don't have MLS Next squads taking the first pick of players, and can implement some roster flexibility to get non dressing MLS Next players play time, which was one of the justifications cited for all this. The biggest obstacle, however, is that the MLS itself and the academies don't seem to care very much about anything under the academy level.
