I think the top 6 in the east are set, we just have to wait on the order. We'll beat Montreal twice more and even if we split those points, the game in hand and easier schedules for the other teams puts them at a disadvantage.
Here's the remaining schedule
Columbus, 42pts/6 games: SKC, Vancouver, NYRB, DCU, Orlando, NYCFC... 3 away
Chicago, 41pts/8 games: Montreal, NYRB, DCU, Philly, SJ, NYCFC, Philly, Houston... 4 away
New York Drink, 39pts/10 games: FCD, Chicago, Philly, SKC, Columbus, DCU, TFC, Vancouver, Atlanta, DCU... 6 away games
Atlanta, 36pts/10 games: FCD, Revs, Orlando, LAG, Montreal, Philly, Revs, Minnesota, NYRB, TFC... only 2 away
Montreal, 36pts/9 games: Chicago, Revs, Minnesota, TFC, Atlanta, NYCFC, Colorado, TFC, Revs... 5 away
Montreal look to have the hardest schedule there in both fixtures, and number of away games. I know anything can happen in MLS, but the odds are really stacked against them here.
