I was quite happy about this as well. Their coverage is far better than was the coverage provided by FOX and ESPN. On the down side, they have changed the interface and I could not figure out how to watch the game in full screen mode.
Fox sucked donkey balls. NBC is by far the best option for us, and for footy in the US as well. This deal will help the MLS too in terms of keeping up interest in the game as a whole.
