The Arizona Cardinals and Dallas Cowboys are currently playing (preseason) Sunday Night Football at AT&T Stadium, and NBC introduced a new feature for their broadcasts.
It’s called the “Green Zone,” and it’s used on third downs to show viewers how far a team has to go to get a first down.
Wait, isn’t that what the yellow line is already for? Yes, but this shows the space — highlighted in green, so, greener grass — an offense needs to cover in order to get a first down. Or… to reach the yellow line.
