Here's the problem with the current offerings because of the alignments we have.
Now that C-USA has signed the NFL network deal, only three of those give you that. Sling, Playstation Vue, or Fubo.
Then you begin to parse those out, because we are also on CBS Sports Network. Sling doesn't offer CBSSN. Fubo does include it, but Fubo doesn't have any of the ESPN channels making it a non-starter. PS Vue offers CBSSN as part of a higher package which is the same package the NFL Network is in.
That said, the package with CBS Sports Network and NFL is $55, which is in line with the cost of the other services. But it also gives you access to the ESPNs as well as FS1 and FS2.
If you're looking at it purely from where C-USA is carried PS Vue Core package and above is really about the only option that's going to give you everything you need.
Hulu and You Tube TV are good options too as both give you everything but the NFL Network. But if you want NFL Network too, PS Vue is it.
