I've never used Roku, but I do have Hulu. I say all the time that we have hundreds of channels and nothing on TV fit to watch. I have watched more shows on Hulu recently than on satellite. They have a lot of reruns that you can watch whenever you want. They also have some new shows a few days after they come on TV. But I don't ever watch those. I think it costs about $8 per month, or $15 without commercials. You can watch on your computer and I think they have a free trial so you can see if it has any shows that you like. You will need a pretty good internet connection though.
Also, most everything on ESPN can be watched either live or as a replay over the internet. I watched a lot of baseball games that way this season. As long as you don't find out the score before you watch it later that night you really don't notice that it is a replay. Sometimes I would find out the score on purpose before I watched so I could see if I was going to be wasting my time watching them lose.
I have watched the football games on CBS live from my iPad before when I wasn't able to be home on a Saturday afternoon. So I know that works. There are lots of ways you can watch TV over the internet now a days, and a lot of them also happen to be free.
Maybe you can get it all figured out before football season starts. Try this link for CBS and see what happens:

The rest will probably be on ESPN, so you might be able to still watch all of the football games.
You can try most of it out on your computer, and if it works then you can see about buying something to hook it up to your TV. Those little boxes you buy at Wal-mart just make it so you can watch it on your TV screen instead of your computer screen.
