The GT idea sounds a bit out of character from what the B1G had been using as their strategy but if they've decided to alter their approach it could be plausible.
Their stance on the BTN had been to have it required as a basic channel, giving the B1G revenues for every household that has cable (Cablevision, Comcast, Time Warner, etc), telephone company fiber optic or similar (FIOS, U-Verse, etc.) or sattelite (DirecTV, Dish) while a pay tier would only give revenue for households purchasing that tier. By having a school located in an area (state) where enough of the population would demand the BTN (for the local school) on basic, this would assure the B1G basic access and therefore highest revenue. I don't see how GT can carry enough of Georgia to get the BTN placed on basic.
The B1G is either softening their stance or they have something else in mind. I still believe that this is a shot to the bow to convince one or both of UVA & UNC to leave the ACC before the ACC starts sinking and the B1G as a lifeboat has sailed. It could be someone (B-12?) trying to rattle some cages to strike at the better football assets (who to date hadn't been willing to jump from the ACC to the B-12).
I personally believe that with a better hire when Edsall left for UMD, we would have been at worst a tossup with Rutgers for the B1G and (if they did choose Rutty) that we would currently be deciding if the ACC would be a better move than waiting for when the B1G expanded further. I also believe that at the moment we are still on the B1G's radar, but nowhere near as high as we could or should be. My gut tells me that UVA is their prime next target and if they can get UVA & UNC as a package, they'll stop at sixteen for a while. I also believe however that if they get UVA but cannot get UNC, we will be in play (very seriously in play). One additional possibility (that I don't yet see as plausible as I still don't see the financial benefit to eighteen members but I have been wrong before) is that the B1G adds UVA, UNC, Ga Tech (and for the record, sw North Carolina borders northern Georgia) and UConn.
