In the last 9 years the loudest two games I’ve been to were Auburn 2014 and Ole Miss 2015. Basically revenge games. LSU 2013 was loud by Alabama standards, but nothing to compare to those two games. Granted I didn’t go to the 2011 LSU game, so that maybe up there.
I think the best comparison I can give is comparing a 6-6 Auburn team playing us at JHS to 2012, 2016, and 2018 Iron Bowls at bds. That trip to Auburn was one of the loudest and hostile trips I’ve ever been to, but those Auburn games I mentioned at BDS you couldn’t tell the difference if Arkansas was in town or Auburn. It was basically a dead atmosphere.
I think age demographics plays a role in it as well. Alabama has had this majority of older fans occupying TP seating and less 25-45 years olds there. Then there is this constant war between younger fans and older fans about stadium etiquette but at the same time this constant debate of why BDS is probably The quietist 100k + stadium in the country.
