about 200,000 BYU fans throughout the United States.
BUT that doesn't mean that more than 10 people from each Ward will be watching BYU now that it's on a real channel.
Plus, I have no ties to Boise State, but if Boise State was playing Ohio State, or Nebraska, or Wisconsin, I would watch. I think people will watch a BYU game that features BYU and Nebraska whether they are a fan of either team or not.
Also, when BYU goes to Mississippi or Chicago or Washington DC, more than ten people from those wards out there will go to the game and cheer for the Cougs.
