You CAN but only if you have a cable login. So if you aren’t paying for cable NBC won’t let you stream anything.

NBC should eat 20 dicks and die for their coverage in general, but the one upshot is that you can stream anything when it’s live. Like I know in Canada you can’t stream women’s field hockey games only men’s. The Canadian men made it to the games and the women didn’t, but my friends there are sneakily watching BBC coverage to get the women’s games. American men didn’t make it into the olympic field hockey but at least I am able to watch all of the men’s matches.
