The Saints, always popular, have transcended, now lumped in with New Orleans’ institutions – Mardi Gras, Louis Armstrong and red beans on Monday. They’re woven into the fabric of the town … because they stayed. Private girls schools now let the students wear Saints jerseys to class on special days. A friend of mine, who lives in Uptown and grew up going to games, says the feeling about the team has changed. He’s an oil-and-gas man, a Republican, not prone to fits of hippieness. “The last four years have been very special in the city’s attachment to the Saints,” he told me. “I am not one to do a lot of reflecting back on Katrina, but there is clearly a line of demarcation there.”
