I don't know about Cox but with Comcast they kill you the Internet rate if you don't have a TV package. We currently pay $67/mo for our Internet with Comcast. The wife has Hulu Plus ($8/mo). If you add on Sling TV that's $95/mo. You can get a great cable TV package (sports channels, HD, etc) on a 2-year deal with Comcast for $90. It reaches a point where it's not worth the hassle to cut the cord. The good thing with Sling TV is that you can start and stop it whenever you want. So if you only want it for college hoops, you pay the $25 Nov-March and then cancel it.
The wife and I have been cord-cutters for a year and a half. I cancelled Comcast after my 2-year deal ended and my bill shot up to $120/mo. They wouldn't give me a deal even close to what I was paying during my 2-year contract so that was the end of that. My solution was to put a Slingbox (NOT Sling TV and not related in any way, shape or form) at my folks' place which gives me full access to my old man's DirecTV. This has worked out great for me, it's "place-shifting", not streaming like Sling TV, Netflix, Hulu, etc. You attach the Slingbox to a STB and you have full control over the box remotely (use the guide, access the DVR, change channels, etc) It's $300 to buy the hardware but there are no subscriptions or monthly fees and the device pays for itself in a few months. To date, we've saved nearly $1,000 thanks to Slingbox.
I have a cheap HTPC I built for Slingbox connected to my 55" Panasonic Plasma but it's also great that I can put whatever I want on my laptop or phone while the wife is watching some trashy show on Hulu. We have an agreement that I get to watch UConn & Knicks (and Jets, blah) games on the TV but all the other games I'll watch on my laptop. It's worked out well, there really isn't much compromising anymore and I get to watch every game I want to watch, just some are on a laptop instead of a bigger screen. The one thing that really pissed me off is that the mobile app is $15 (per device, which is absurd considering you just bought a $300 piece of hardware). I wound up buying it, and it's been worth it, but still doesn't justify those bastards being greedy!
