Been to seven NFL venues.
What stood out is the lack of college feel. OP might recognize as soccer songs. I’m accustomed to Bills home game.
Other NFL venues often pipe out stupidly loud, poorly timed music. Fans get effectively “cut off” from building group energy. Commander's game this year, crowd couldn’t help the home team because the music cut them off.
Sure, concourses are all better than BUF. But, I have been shocked at atmosphere bland.
Like going to an indoor movie (IND DC DET MIA) vs. U2 outdoor rainy summer concert (BUF GB). Both venue types are technically entertainment but the later is an exciting entire group experience.
P.S. my 20s yr old kids love BUF and thought DET sucked but they do now understand why I brought them only to quiet preseason games as youth!
