I think the issue is a lack of overall fanbase. People who are truly interested in GT football is probably far and few between within driving distance of Atlanta.
While there are thousands of Tennessee, Clemson, uga, Bama fans who will drive hours (4+) on a Friday/Saturday to see their team play. We are lucky to grab 20-35k of the people who live within 1-2 hours of Bobby Dodd. Have to remember most of our grads leave the state. Then on top of that most of todays students at GT have zero interest in football being from different cultures.
GT has to gain the hype of the city by WINNING to land sidewalk fans more than anything. We need the casual 30-50yr old who enjoys watching football to come to a GT game. Maybe after a couple winning seasons they become true fans. Our alumni alone will never cut it. I'd say for every 1 GT alumni that has serious football interest, there are 15 uga grads that have serious football interest. We have to gain sidewalk fans. Which means winning, and offering things that are different to other places. Sadly we can't make something like the braves have around Bobby Dodd, but GT needs to come up with something.
