Why? Is it the New Orleans thing that makes you a fan? You're from NYC, so I'm just curious as to why a Saints move would turn you off the team.
I became a fan because my family is from the South, so I was raised to be a Saints fan, it's part of the geography. I love the city of New Orleans, the fleur-de-lis and all that. If they moved, it just wouldn't be the same team to me, even if they kept the colours and the name. I just couldn't root for the Los Angeles Saints.
I can relate to this...I've never once been to New York, yet all my favorite teams are NY based. Family is from there. I have no real explanation why I like the Bills rather than the Giants and Jets though.
