Most of the games and especially the big ones, these days, are on CBS or ESPN so should be pretty easy to catch on any TV provider. Especially with the SEC's new TV contract, you might have to try to miss games. Some of the lower profile games may end up on ESPN Gameplan, but I think all of the above give you access to that package now. I think DirecTV does have exclusive rights to the NFL's big PPV package.
