Speculation is that if there is a traditional ACC network (there will be one of some form, just don't know if it's a traditional type), that they would share a lot of the same facilities the SECN is using in Charlotte so there would be a lot of shared cost.
Second, I don't know why people keep thinking a potential ACC Network means that ESPN has to shell out money like it's a right's fee. It would be totally different. It would be a totally different partnership where it would create it's own revenue and generate it's own expenses. It is completely different and separate from the rights fees the BIG just got paid. I don't know why people don't get that.
If it would lose money, they won't go forward. If they feel it would make money, it will go forward. But it is not a rights fee negotiation or where ESPN is paying additional money on top of what they already do.
ESPN leases space in a suburban Charlotte business park for SECN, ESPNU, and ESPN Regional syndication. It would be very simple for that location to be the hub of ACCN.
Also, Raycom has their own building in Charlotte (dont know if they own or lease) and if that building could become part of the deal of acquiring Raycom Sports.
