Did this a week ago for ChiCitySports.com, decided to come to a more active soccer forum to garner opinions. I tried to keep most regional rivalries together, unfortunately couldn't manage things like Fire-DC or Fire-Revolution. Eastern Conference Atlantic Division D.C. United New England Revolution New York Cosmos New York Red Bulls Philadelphia Union Central Division Chicago Fire Columbus Crew Montreal Impact Sporting Kansas City Toronto FC Western Conference Northwestern Division Colorado Rapids Portland Timbers Real Salt Lake Seattle Sounders FC Vancouver Whitecaps FC Southwestern Division C.D. Chivas USA FC Dallas Houston Dynamo Los Angeles Galaxy San Jose Earthquakes Top three teams in each division make playoffs, seeded one through three. Second place plays Third Place in single game (I know this doesn't give all teams a playoff game, but other leagues have this too, MLB Wild Card game, and NFL). Winner plays division winner in two-game aggregate Division Finals Series. Winners of Division Finals play the other Division Finals winner in their conference in single game in Conference Championship Game. Winners play in MLS Cup.
