I was wondering if there are any multiplayer leagues for PB19, I saw the forum for PB18, but I don't even see a section for that in these forums. I'd be open to making one / making a discord for it. Is anyone interested? I've also never done this so it'll be a learning experience.

Currently, the CSL http://www.championshipleague.com is DDS 3, but the league is transitioning over to DDS 19 in a couple of seasons.

Like Tim said above, we will be transitioning from DDS3 to DDS19 in the very near future. The league right now doesn't require you to own DDS3 to be a part of the league and many members are more than willing to input depth charts and sub rotations for those who don't own the game. We have an open team and if you're interested I would highly suggest getting in now and being a part of the transition to DDS19 with us.
