I'll second the Slingbox recommendation. I've been using my Slingbox Pro-HD for five (5) seasons now with an initial cost of $75, so $15/yr by now - and it's been great. Honestly people who come over to watch can't tell the difference between the antenna and the Slingbox. I recommend the Slingbox Pro-HD (older model) as it is available now on eBay for $40 shipped and can have an antenna plugged in (it has an ATSC tuner built-in). Just make sure it is set up for internet viewing before you leave for the year!
Reddit NFL streams have been about 80% for me, sometimes they get taken down during the game which is frustrating. Slingbox, once set up, is pretty much 100%.
