If TFC can score just one goal today - they will have a HUGE advantage. That would mean NYC would have to score 4 to win. If NYC wins 3-1 today TFC advances based on the road goals tiebreaker.
If NYC wins 2 - 0 in regulation - the game goes to overtime with next goal wins.
With Montreal - with their 1 - 0 win in Game 1 - if they can score a goal then the Red Bulls will need to score 3 to eliminate them. a 2-1 Red Bulls score would mean the Impact advance. A Red Bulls 2 - 0 win advances the Red Bulls, a 1 - 0 regulation score for Red Bulls means overtime.
It was huge that both Montreal and Toronto did not allow a road goal last week.
