Essentially any teams that have qualified for the playoffs should submit their playoff rosters (list of players playing in IRL playoffs).
Teams that have missed the playoffs have their team sheets adjusted to plan for next season (contract years shifted to reflect updated cap space for next season, etc).
By Sunday, the official standings should be completed by pickup and the dispersal draft will begin (order and dispersal list on first post of page 154). Not sure when draft lottery phase 1 begins, but it's to somewhat prevent tanking in GML where all lottery teams have a pre-lottery here that could shift around the order of which team we are tied to when the real draft lottery happens (so our current standings don't fully determine which team we are associated with IRL).
I hope I explained as best as I can. Feel free to ask for further details if needed.
