I've been to Eagles games in Philly as well as about 6 other NFL stadiums. The Eagles fans are, and this is by a dramatic margin, the harshest and worst crowd in any pro sports stadium I've ever been in. More drunks, more fights, more booing of injured players, more throwing crap, more of everything that makes such an event dangerous. I couldn't wait to get out of that stadium.
If it was 30 fans that did that, how exactly did they do it every game over the course of many years from most parts of the stadium?
