This. It's something I've been talking about for years in regards to GT in the B1G. GT fans, for all of our faults, will show up for "brand" names. How many "brand" names are there in the ACC? Clemson, FSU, and arguably UNC in football. VT was a popular ticket when they were good. When Notre Dame is here, BDS is full. Miami is a shell of its former self, and you can make an argument that so is FSU. Our ACC football attendance is predicated on how good a team is.
In the B1G, there's Michigan, Ohio State, Penn State, Michigan State, Nebraska, Wisconsin, Iowa...and now there's USC and UCLA. I'd argue that it doesn't really matter how good those teams are, fans will show up to watch those teams play. They're "brand names" which draw watchers on their history and name. Of course, when they're good, even more fans show up. The other thing is Atlanta is home to a HUGE population of B1G alums. It's one time a year that will probably not only draw a big alumni crowd in the state, but surrounding states.
Now imagine if GT is good to very good. Playing those teams, and winning, catapaults GT's brand higher on a national level than it would if we were beating NC State/Duke/Wake Forest/Syracuse/BC/whatever mediocre ACC team is on our schedule. It's a rising tide lifts all boats situation that made the SEC what it is today.
GT stands to gain A LOT from the move to the B1G.
