Twitch has announced a couple of new features that aim to make Thursday Night Football an even more exciting -- and worthy -- watch. First up is the TNF Live Extension, where you can make your armchair coaching heard. Predict how drives will end, who will win and more, and if you call the right shots, you'll end up on the leaderboard, which you can gleefully flaunt in front of your friends next time they make a lousy call.
