Queue the 'it's the drink company's fault' comments.
There are way too many people in all 3 sections who just don't sing or even bother to clap their hands. I don't blame the supporters groups for this, you can't make people participate when they don't want to.
We are honestly bottom half of the league in terms of atmosphere these days. Of the top of my head we edge out Houston, Dallas, Columbus, New England, San Jose, and maybe DC. Our attendance has been flat for a long time and the Southward seems less energetic each year.
Say what you want but when people think MLS they will think of Seattle, Portland, Orlando, Minnesota, LAG. Atlanta looks to have buzz, Toronto enhanced their stadium and can draw. DC is building a new stadium and I think that will help their atmosphere.
This team has a great arena, has been at the top of the table for several seasons, and is in the world capital.* When you consider those things, its pathetic how some of these markets are totally outclassing us. I haven't personally driven to all of these markets but on the outside looking in, people seem to care. With us, no one seems to care. I still have to explain to people who the Red Bulls are. Don't know if things would be better without the drink or not, honestly. I don't have any suggestions either. NJD won three cups and still no one cares about them. Maybe its a NJ thing...lacking a nucleus/hub. Many sports teams all play in same area in a city. RBNY and NJD sit outside the action and get forgotten about. Philly has the same issue. Basketball/hockey/football/baseball are all right there and they get to play the red headed stepchild and play in Chester. I think it hurts you.
*Queue the NJ is not NY crowd
