Half the playoff bracket programming is based on the 16 playoff teams from last season. The other half is based on the 16 teams that didn't make it. With them, I structured it based on how they finished in the standings as I have done with my previous season ROMs. I think I made Seattle an 8th seed because they had to be included and it made sense.
Last season/playoffs was unique, to say the least. Thankfully, we get to return to a normal structure this season. I will update the playoff trees when I do a playoff version of this ROM, later this season. I'm not going to do it sooner unless you have a crystal ball.
