The DVHL is fine. It sucks losing two quality organizations.
The DVHL has plenty of options. Right now it has an "American" and "National" division at almost every level. That can be merged. Maybe not ideal, but AHF has its own competitive balance issues.
Or they can supplement with the EJEPL. Like every body else did in the past before the AHF sucked up all those games.
Or they can play in multiple tournaments. Like every body else did in the past before the AHF made you play in Defender.
Lots of ways to get to 40 games.
Or they can merge with the NJ teams.
