I don't know the stats on Maryland area, but Atlanta is home is the largest B1G alumni base outside of the midwest. I believe only Chicago and Indianapolis...maybe Cincy have a larger B1G alumni base than Atlanta.
Let's be honest, it's not like GT is killing it with attendence in the ACC anyhow. Even if we remain the same, we would be pocketing WAY more money from the B1G than staying in the ACC. Attendence is an excuse for those that just don't want to change when it really isn't an issue for us anyhow. We're not Clemson or UGA with fans that actually like to travel...heck, a lot of fans don't even go to home games.
The “Maryland area” is also know as Washington, D.C. Washington has tons more B1G alumni than Atlanta. ATL can’t even hold a candle to D.C. when it comes to that. Other cities with more B1G alumni than Atlanta include: San Francisco, Los Angeles, New York, and Denver.
As of now, GT relies on opposing fans to fill BDS. The only sellouts that occur nowadays are when the majority of seats are filled with the opposing team’s colors. If Maryland (the D.C. market) and Rutgers (the New York market) can’t rely on their large, local B1G alumni bases to fill seats, why do you think Georgia Tech can? As I pointed out in Maryland’s case, I’m sure ticket sells would skyrocket for a couple of years until every B1G team has rotated through Atlanta, but after that it’ll be the same old story.
Clemson is a local team, a conference rival, and a historical rival. There are plenty of Clemson fans who have friends, family, coworkers, and see strangers who are GT fans. Their campus is a little over 2 hours from Atlanta. Countless alumni live in the ATL, I’d be willing to bet my life more than any B1G team. I’m positive they would have more interest in attending a game at BDS than anyone from Ohio State, Michigan, Wisconsin, Penn State, etc. after the novelty of Atlanta wore off after a couple of trips. Same goes for Miami and Florida State.
