I'm surprised there's so many fans on the site. I figured everyone in Carolina hated Atl
Well for a very long time Atlanta was the one in only team in the entire southeastern united states.
The Marlins first season was '93, Tampa was '98, and Washington was '05. Before those teams the next closest city with a MLB team was either Cincinnati, Baltimore, or Houston. So the braves were the closest team for most people in GA, FL, NC, SC, AL, MS, TN.
My braves fandom pre-dates the existence of the Carolina panthers and their rivalry with the falcons. It used to be that Atlanta sports teams represented a huge chunk of the nation due to the lack of big metropolitan areas in the south. I think it's safe to say that most true southerners are braves fans.
Plus, the other teams in the "southeast", the Marlins, Rays, and Nats aren't really in the south at all because we all know the south stops at Richmond going north and at Gainesville going south.
