My recollection is they stay away from those spots a lot because they know that college football has a huge following. I do not see the Red River Rivalry being played in prime time. And most often it is an 11 AM CT kick off.
ABC has not failed to take that game in the last 12 years on their main channel. It still doesn't make sense to me that FOX would pass up a middle of the day game like that...
