Despite having a mediocre year last year, Utah averaged 2.62M viewers per game. BYU averaged 1.08. Utah had 4 games that drew more viewers than BYU's game against Texas (which was BYU's most viewed game and it had a 3:30 eastern start on ABC).
So far this year, with comparable schedules, Utah is averaging 1.71M viewers per game. BYU is averaging 0.95M viewers per game.
I know this is a board of Utah haters more than BYU fans, but viewership smack really isn't a road that you want to go down.
