Putting on a 4-hour or so broadcast of playoff football takes a monstrous effort of hundreds of people and massive amounts of equipment.
"We try to make it look easy," said senior operations producer Matthew Kwok. "That's why we do a lot of preparation before the show."
We got a behind-the-scenes look at Saturday's production: all 10 trucks that bring in cameras and cable, but also things like generators for back-up power.
"In the event of a stadium failure, we are still able to document what's going on," Kwok said.
There are miles of cables connecting the some 40 cameras to the production trucks - and the hundreds monitoring those cameras. (Don't forget the four pylon cams)
To get you those replays? There are 19 separate machines -- just to play back that one play you know the refs missed.
And once the game is over? It takes just about 160 minutes to pack it all up and be out of there.
