Its too complicated this year, but in a regular season, 16 teams are in, bottom 6 teams play a round robin, winner gets #1 OA and then seeding continues #2-6, takes the total tank out of it. It leaves 9 teams in limbo (they would fall into pts as current system is, but makes it exciting.The top seven would also get shafted as well, because they'd have literally zero ability to trade down or out since they're making picks a day later, granted there hasn't been a lot of top ten picks traded in recent years but still.
This year I think the way that would work is Det gets 1OA automatically. 2-6 are RR playoff.
