I'm not entirely sure that no network is a good thing, even if there is a decent check coming in to "shelve" it.
Big Ten and SEC schools have had to capitalize their networks, yes. But they now have an infrastructure to create content - staff, video facilities, multimedia production for recruiting and exposure - that virtually no ACC schools currently have. And many wouldn't have the stomach to invest in that area unless they had to.
BIG and SEC schools had to do so as a condition of their networks. Yes, their content is housed primarily on those networks but the secondary content they're now able to create and monetize indepently, or utilize for recruiting is highly impressive. Many of them had the money to begin with possibly, but they weren't investing in that area.
If you poke around the internet it's unreal what some of the SEC schools in particular are doing now that they have the pieces in place to create content.
My long-winded point simply is that everything from facilities to training table is an arms race now. This is no different. The ACC should think hard about the benefits of being tied to a network rather than just trying to cash a check. SEC schools are already and likely always going to be ahead in revenue generation. You can't allow them to dominate the content wars as well if you truly hope to compete with them.
The PAC12 is what it is, and will remain so because it's landlocked. It's not a coincidence that the Big 12 is now starting to whisper about the Long Horn Network and whether they should be trying to flip that to a conference network. The ACC and the Big 12 are locked in a death struggle to be brutally honest. A locked in, ESPN based network with a good payout and a longer grant of rights that gave schools a built in production arm would be beneficial to the conference in many ways given the changes to the digital landscape.
