Do you have TMobile by any chance? They've given away MLB TV every year so you could use that for Sox and Directv Now for the majority of the rest.I've read good things about YouTube but the channel lineup seems limited. There are at least 3 or 4 that my wife and daughter love that aren't offered. I think the only way I can sell this plan to them is if I can convince them that they won't lose anything.
Can I assume that with any of these services I still couldn't get NESN since I live in NY?
Edit: I have Directv Now and like it. I haven't tried the others, so there may be a better option, but the DVR function works well, it has a traditional looking guide setup and gets me about 90% of what I need (no MLB, NBA, etc). For the VOD channels, I use an antenna and pickup CBS, FOX, NBC, ABC and a few others and the quality is as good, if not better than what you get streaming. It is a bit of a pain in the ass if reception is an issue and having to flip between video sources, but it gets the job done.
