If you were to really ask who the true New England Revolution rival is, the Chicago Fire will be on the list, perhaps still at the top for many.
Multiple playoff series from the 2000s combined with both teams being perennial powers in the East and MLS made it easy for these two teams and their fanbases to dislike each other.
Then 2010 rolled around, the dark ages as it were. Chicago is still mired in a streak of woefulness with just one playoff appearance in the last seven seasons. New England has been resurgent of late thanks to a solid rebuilt roster but took a big step backwards last year on the field and missed the playoffs.
