Right now it is playoff season, so there aren't really any standings.
But there still are favorites to win. I wil give two viewpoints, myself, and a website called 538.
538 is a website that has chances for political races, and the latest sports games.
They also have tons of articles on sports and politics.
Toronto FC vs. The NY Red Bulls
Leg 1 is already done, with Toronto having a 2-1 lead over NY. 538 gives Toronto the win, with and 87% chance. I agree with Toronto getting the win. They broke the MLS record for most points in a season, and they have Sebastian Giovinco.
NYC FC vs Columbus Crew
The first leg is already done, with Columbus having a 4-1 lead!
538 gives Columbus the win, with a 90% chance, and I agree,
you can't come back from a 4-1 loss against Columbus.
Seattle Sounders vs. Vancouver Whitecaps
The classic Cascadia rivalry.
In case you want it her is a link to 538.
