I tried mapping out all the playoff seeding scenarios below
Great 8
Visionaries is the 1 seed with a win vs Mill City or a Flashover loss. Otherwise they are 2
Flashover can move up to 1 if they beat Beware and Mill City beats Visionaries. Otherwise they are 2.
Mill City clinches the 3 seed with a win or a Beware loss, otherwise is the 4 seed (as long as they don't lose by 100+)
Beware can get as high as the 3 seed with a win and Mill City loss. Most likely they will be the 4 seed which requires a win with Mill City also winning OR Tar Team winning a close game vs Pressure. If they lose and Pressure wins OR Tar Team wins by a large margin, they will drop to 5.
Loser of Tar Team vs Pressure will be the 6 seed. Winner has a chance to move to 4 but most likely will slot in at 5 pending PD and Beware's game
Big 8
Big Gulp clinches the 3 seed with a win or if WW and 10inch both lose. They are the 4 seed if they lose and either WW or 10inch also loses, and the 5 seed if they lose and WW and 10inch both win.
The final playoff spot could come down to a PD tiebreaker between White Walkers and 10inch Vert. Both play tanking teams their last game and racking up a large victory could be the difference of playoffs vs a relegation series. Either could move as high as 3 with a Big Gulp loss.
