It's definitely more than 200k a year. You need people to staff cameras, set up equipment, tear down, work the stat booth, broadcast the game, etc. Even a small scale production is going to need at least 3 or 4 salaried individuals to do it - football & basketball could easily have dozens of people. Maybe some are low paid students, but with the price of the cameras there will be at least a few full time salaried employees on a broadcast.
