rivalry. It means that BYU now won't overlook Arizona. Prior to the UU-AZ game, many people were assuming a BYU win against AZ. That could have been a serious mistake.
I have been a fan long enough to know that BYU is most successful when they are underdogs and when they take the other team seriously. Overconfidence is the bane of BYU sports.
To the mods: this is the correct category 😀.
