Road Games:
2013 - Montréal , 2014 - Orlando (Disney Classic), Montréal
2015 - Columbus, New England, Montréal
2016 - NYCFC (Leg 2 Conference Semis), Montréal (Leg 1 Conference Final)
2017 - Ottawa (Leg 1 Canadian Championship Semi), DCU, Red Bulls (Leg 1 Conference Final), Columbus (Leg 2 Conference Final)
2019 - Montréal, NYCFC (Eastern Conference Semi @ Citi Field), Seattle (MLS Cup Final)
I think it is because of the East/West divisions. At a certain point, only NYCFC can catch us, so they get 1st, we get 3rd and someone from the West gets 2nd.
The first chart is for playoffs in our division (only 11 postions), the last is the race for the supporters shield (22 positions).
