I'm gonna explain this level of Barner logic to y'all - no, it makes no sense, but oh well.
When football began shortly after Noah got off the boat, fans gravitated towards the flagship school of the state (for the most part) - Alabama, Mississippi, LSU, Texas, Oklahoma. Fans of the game who didn't have an NFL team back in the 30s and 40s gravitated towards interest in the state's 'big name,' which in the Heart of Dixie was the Crimson Tide, for better or worse.
A fan was more likely to pull for the 'lesser known' school (Auburn, Okie State, ATM) if he or she attended that school for obvious reasons. The problem, of course, is that that doesn't mean every single fan of Auburn or ATM has ever even set foot on campus - it's a regional thing. If you grew up in Lanett like my Mom did in the 50s, you primarily heard Auburn games on the radio (and her Dad was a Ga Tech fan going back to the days of John Heisman; her brother actually played streetball and tag and those games with Auburn's 1961 quarterback Bobby Hunt and lineman Dave Hill).
But it became a fallback argument when Alabama (in particular) was winning title after title using this kind of 'logic' - "anybody can pull for a perennial winner but you're a 'better or more loyal fan' if you pull for a team that loses a lot of games." So unlike Alabama fans - who are assumed to all be front-runners and can't be found when the Tide has a 3-9 season - Auburn fans (or in this case ATM as opposed to UT) are REAL fans because they're there either way. So goes the story....
go back and look at the empty seats at Jordan-Hare in 2012.
Those same seats were packed to the gills just a year later...oh, when Auburn had a pretty decent team on the field.
Now - I'm not criticizing Auburn or their fans IN ANY WAY by noting the empty seats......just let's quit the pretense that fans of the 'second school' in a state are somehow 'real fans' as opposed to those pulling for the favorite. It's true some are but that goes both ways.
It really doesn't matter. I've never been to an Atlanta Falcons game ever, but I still pull for them.
