It's true. Yeah, I've been annoyed that USU has beaten BYU badly the last two years, but I don't really think of them. It's like when BYU was in the MWC, I never considered TCU a rival. I considered them one of the better teams to beat. When Hawaii has beating BYU in the WAC days, they weren't a rival, but I did want to beat them when the game arrived.
I'm a BYU fan that casually follows BSU, USU, WSU and UVA — very casually follows and roots them. I hope each does well. I used to casually root for uu, but the grief from uu fans have turned me off. I usually don't even know when/who they are playing. It's nice.
