The Fox Sports article cited here is just a clickbait list the object of which was to say the snarkiest thing possible about every NFL stadium. So the Advocate isn't helping to clarify matters by highlighting the snark in the headline they chose to run. Even within the context of the list, there are still 11 "worse" stadiums than the Superdome according to the article. By doing that the Advocate is helping to imply that we're supposed to pony up another billion dollars or so for Tom Benson (or his successor) sometime soon.
Anyway, the whole thing is dumb. The Superdome is a fantastic building and should be revered as such. It's the "last of the true domes" for a reason. It was the one that got done right.
