It's stupid as fuck and all MLS fans fucking hate it, that I assure you.
Top 3 in the West are seeded 1,2,3 in the West conference, same goes for East.
Next best 4 overall are the "wildcard clubs"
In the wildcard round these 4 clubs play. 7 hosting 10 and 8 hosting 9. The lowest remaining seed after these 1 game playoffs goes to play the top club from the season (LA Galaxy) and the higher seed plays the other conference winner (Sporting KC).
NYRB being the 10th seed and beating 7th seeded Dallas is why they play LA.
3 of the 4 quarterfinal teams on each conference bracket are the top 3 as mentioned before, the other two remaining spots can go to any team through the wildcard stage.
Quarter finals are 2 legs, Semi finals are 1 and the Final is 1.
Fucking TERRIBLE. Die in a fire Don Garber.
