It is a generational thing but not in the way you might think.
Old Saints fans remember the pre-Payton and Brees era Saints.
It is 2025. It's been 19 years since the era of "aints". Nationally, the Saints are more successful to most young adults who watch football than the Cowboys.
A lot of people are simply not used to the Saints being a bad football team. Even outside of Saints forums, I saw countless comments from people who are fans of other teams going "the Saints used to be feared, what happened?"
A lot of people have simply forgotten what being a genuinely bad football team looked and felt like, and are desperate to get back to no longer having that feeling.
