Official online stream
To get the official stream from WatchESPN, just enter your cable provider (or your parents' cable provider) and information. If you have the ESPN app, you'll have access to all the aforementioned alternate productions of the game.
Other live streams
Facebook Live and YouTube should have live streams of the event. These are, however, notoriously unreliable, so you may have to jump from stream to stream. Google will be your friend in finding these and other live streams.
Head over to the College Football Streams subreddit to find more streams of the game. Know that this could be on the shadier end, so it's hard to vouch for your computer's safety if you embrace these dark arts (aka potential viruses and spyware and whatnot). Be cautious and smart.
