I'm just wondering if anyone knows if there's any sort of program like MLB.tv for football games, since I'm going to college next year and still want to be able to watch as many football games as possible. Apparently DirecTV has their own system but you have to be a Sunday Ticket subscriber to get it. Is there another way, or has the DirecTV monopoly struck down my chances?

Last year there was a free NFL video streaming option.
I highly doubt that it's fully legal, so I won't link to it. The video quality was awful, the interface is clunky and I was happy just watching whatever was on while watching the nfl.com feeds. You can find it on Google, if you want to look.
Alternatively, if you'd be satisfied with just audio, nfl.com has Field Pass and Sirius radio carries the NFL.
