You dont need to have an account. Just go to this website https://www.reddit.com/r/nbastreams/ and find the Jazz game when its on. Inside will be a bunch of links to games. I would highly recommend having an ad blocker on your browser, otherwise the popups will be overwhelming. If you are only getting the chats still it might be because the streams tend to be flash. If you are using chrome browser you probably have to allow flash on the web page.
Thanks, got it figured out. Will be watching the Utah game in a few without cable. Jazz later tonight.
