Well, they said that GT will have control of the tickets in all of the games except the Clemson game, and will have more control of the Clemson tickets than was had for Tenn. For ND 2020, I am assuming that ND will not have access to lower level tickets between the 20s, so the good seats available to GT season ticket holders should be double what it was for Tenn. They also said that GT would have access to the suites (except for Clemson I assume). That means that people who sit in 106 or CL1 at BDS should have access to seats close to the middle. People who have suites should be in suites instead of on the 50 yard line.
If it is treated as a home game, then the visiting fans should get customary "visiting" fan locations.
