Fairly easy! You usually show up a couple hours before the game begins. You'll set up your camera while the Director sets up their station. You work with your other team members to uncoil your lengthy SDI cables and make sure the connection from camera to the Director's station is functioning properly.
Then you'll take a break until game time.
During the game, you'll have your assigned job as a cam op.
After the game ends, you'll wrap up your station, assist in getting other stingers and SDI cords coiled and wrangled and you'll bring your tools back to the office.
