It would be interesting to see if those 17 average out to specific channels, or categories of channels. i.e. Sports Broadcasts.
Honestly, I'd be a cord cutter and I know a lot of other people who would as well, if there were *reliable* alternate way to get the sporting events I want to watch. Baseball, Hockey, Soccer, Auto Racing, just to name a few that you can't really get outside of a cable subscription. Football *could* be piled in there as well, mostly because there are relatively few games on the broadcast channels on any given weekend for a given region. However, NFL is probably the *most* available of any sport.
I never watch anything else that can't be reliably streamed from Netflix, Prime, Hulu, etc. But I have to pay for all of it to get the sports. ):
