No one who lives, or is from, Louisiana can accuse anyone of being a "bandwagoner" fan of the Saints when they themselves support teams from elsewhere. From the moment the Saints were formed, announced on November 1, 1966, I have been nothing but a Saints' fan. Prior to that, and secondarily afterwards, I was a Baltimore Colts' fan....Johnny U!...I was also a Baltimore Orioles' fans for years for the same reason, every summer we went to Maryland to visit relatives and my Uncle Pat held season tix for both the Colts and O's. We would see a couple of O's games and at least one Colts' preseason game when up there. I was young, the Colts and O's were good, and I became a fan. But with the advent of the Saints, that was it for me, nothing but black & gold. I did, however keep the Colts as my second team and cheered them on as they beat a certain team 16-13 in the Super Bowl...even that completely faded away when the players I liked back then retired.
I have also been a Notre Dame fan for as long as I can remember. I am not passionate about them, but I do hold ND as a second team, mostly as a casual fan. Unless they play Tech, I will root for ND. But, I don't really care, don't get upset if they lose.
The only reason North Louisiana flocked to the Cowboys pre-Saints and even during the Saints' early years, is because they were good. If Dallas was a consistent 2-12 type team year after year, there would be no Cowboy fans to be found anywhere, let alone in Louisiana. By definition Louisiana Cowboy fans are the very epitome of bandwagoners.
So, for someone to criticize lifelong Saints' fans for being Saints' fans, and they themselves nothing but bandwagoners, is laughable.
