So growing up a packers fan in Virginia I have thought about this very topic many times and found many options.
1. Get direct tv, not a big fan since I have Verizon Fios(fiber to my house) and being a satellite communications engineer I would hate for my ability to watch tv be reliant upon the weather(rain fade on Ku band is very noticeable, but C band is to expensive for directv and X band is reserved in the US)
2. Buy a play station, and direct tv offers the Sunday ticket on that(not a bad idea since the play station can also be DVD/ blu-ray player, but I would like to hold out for an apple tv option since I can put that in my pocket and take it to a friends house)
3. Directv will allow you to pay for the Sunday ticket and get online only if you can prove that you are unable to use a antenna to get direct tv service I tried it last year and they are huge pains in the butt about this they were going to come and check the view angles and if you say your HOA doesn't allow it they will send a technician to see if neighbors have satellite antennas.
4. This one takes some work but seems like the coolest option, get a slingbox pro-hd(
