playing situation is really not comparable to utah's....its like they're in different tiers or leagues.
utah is playing varsity and byu is playing JV. you might go watch the JV games, but if you want to see the varsity, utah is the closest.
people can switch. i have seen people switch. nobody on cb wants to believe it could happen, but it can and does. byu is literally not in the same game utah is. so if you want to cheer for a local team playing big time football, you cheer for utah.
