The population is overstated. PA doesn't give a crap about Pitt except in Pittsburgh or WPA. An ACCN isn't going to get coverage in all of PA or even SU in NY State or BC in the state of MA.I get your points but the ACC has one thing the others do not: more people! The BTN is not getting $1/HHD in NYC as they projected, even in most of Jersey they are not getting that much, assuming what I have read is correct, I have not seen official numbers.
Having a larger pool to draw from allows the price to be lower while making the same or more. Personally, I am not concerned about making as much immediately as the BTN or SECN, so long as the ACCN gets up and running with quality productions. Once people realize what is available, then we will see where the true value lies. If advertising for hoops, lacrosse and baseball on the ACCN jumps to levels the BTN can only dream of post football season, then we will know the ACCN will be successful.
Population only matters if you have the flagship programs in those states. The ACC owns Virginia and North Carolina, FSU/Miami have less fans combined than Florida, but they get the ACCN into Florida, Clemson/South Carolina are pretty close, but USCe has more fans in SC, but Clemson gets you in SC, Louisville is second fiddle to Kentucky, but they get you in Kentucky, Georgia Tech IS WAY BEHIND Georgia, but we gotta hope they get the ACCN in Georgia.
The population argument is a Swofford talking point its helpful, but unless the FB continues improving the ACCN will be like what OmniOrange said the Pac-12 network,but with ESPN's backing.
