Lots of schools have similar problems and don't have these problems because their fans and alumni support athletics disproportionally to Tech's fans and alumni. Stanford, UCLA, Michigan - I'll exclude Notre Dame thanks to their TV contract - Cal... all schools more difficult to get into than Tech, all schools that have world-renowned engineering programs, etc.
Personally I get really tired of the "engineers don't waste money" argument to rationalize poor support of Tech athletics.
The facts are, even during the "pre-internet, before everything-is-on-TV-anyway" years we struggled to sell out BDS@HGF, and then we learned that it wasn't even 50,000 seats like we thought it was.
In my 22 years since becoming a Tech freshman, I've seen countless gimmicks to "improve the gameday experience" and they are all terrible because they are all manufactured. Our best gameday experiences are the ones that have stayed the same - The band, buzz and wreck visiting various tailgates before the game, coming down the hill together to enter the stadium, our fight songs and the budweiser song.
Just win. And everything changes. Fans come back. College Gameday comes back. The entire world is not against Georgia Tech. In fact ESPN, the AJC, everyone would love a contender in Atlanta.
But a bad program will be poorly supported, especially in major markets. We saw it at blue blood USC this past year, despite their fake attendance figures:
You guys will laugh at me for this but there's nothing keeping us from being the Stanford of college athletics if the academic school wanted to make the athletic department part of its mission and make a real investment in it. And I've laid out here before that I think there's a strong case to do so. It's certainly capable of doing so, financially, I'm just not sure of the governance issues.
