Yeah, it also has to do with a lot of people in Atlanta are not really from Atlanta.
Atlanta also have many people who are bandwagon fans of the Lakers, Celtics, Bulls, Spurs, and most recently Heat fans.
I can't tell you how many people that I know in the state of Georgia who are Laker fans but have never been to LA or even California because there are so many. They are only fans because of their history.
