PACIFIC - Vancouver, Seattle, Portland, Sacramento, San Jose, Los Angeles FC, LA Galaxy
MOUNTAIN - Salt Lake, Colorado, Minnesota, Kansas City, Dallas, Austin, Houston
CENTRAL - Chicago, Detroit, Cincinnati, Nashville, Atlanta, Orlando, Miami
EAST - Toronto, Montreal, New England, New York City, NY Red Bulls, Philadelphia, DC United
Twice against your division, once against everyone else, and one additional rivalry game gives a 34-game schedule.
