Yes, you get more views at the prime time slots on the best networks. Yes, you earn those spots by winning. The list changes over time. The Gators and Badgers need to shape up or they will fall off that list. Auburn, too. Even Clemson. Miami used to be near the top of that list with Nebraska in the nineties. Win and keep winning and great things happen.
