PSA: DirecTV is offering Sunday Ticket for certain non-subscribers this year. They have different plans depending on what devices you'd like to stream on (and for the record PS3, PS4, and Xbox One are all supported). Basically if you're in an apartment, university, or a city that can't get DirecTV. You can check at the link to see if you qualify.
If you don't qualify I'm sure you could try bugging them to see if they'll let you do it anyway.
