I was thinking the same, I have sky but just being tight lol, my uncle is visiting from Canada and has got rid of their equivalent of sky as he streams a lot like the English football etc, apparently it's big over there and the cable companies have lost a lot of customers in recent years because of it.
The only problem that might occur with the fight is the amount of money envoy end and pumped into it they will probably block the signal somehow it's the same with the nfl you get a few mins then it's gone.
