I won't advance through the playoffs until we have a plan in place for how we will handle the offseason. Right now my thought is we will have a roll call for a couple of days to see who is still active and then decide how we will handle GM-less teams. I need one GM to add to a fake league I am going to make where I will sim the first season and playoffs and see what teams without a GM do come offseason. I would think they will qualify their RFAs (the biggest issue last time) but I want to see for sure before we advance to re-signing.
I believe that teams that have no user and are CPU controlled will attempt to sign their FA's and qualify RFAs.
I also know from multiple experiences that teams with users that are not actively participating will obviously forget to sign and qualify and as a result those teams get gutted of their valuable players.
