MLS Decision Day 2019 is all about seeding for the Seattle Sounders. The quick version is that if they beat the San Jose Earthquakes and FC Dallas does not win on the road to the Colorado Rapids then Seattle takes the two seed. Fifth is only available if the Sounders lose and the Portland Timbers beat the Vancouver Whitecaps on the road. There are many combinations that result in the three or four seed (and a home game).
San Jose is a broken side. They’ve hired their 2019 coach (Matias Almeyda), but he’s not actually coaching right now.
