did not give up 40+ pts to anybody.
I look at trends. I'm not saying BYU is going to beat Arizona, but it's game 1. Their O will be rusty. All teams are on game 1.
It's game 1. BYU is not known for giving up 40+. Zona isn't known for scoring 40+ except on bad D's. If the bettors are thinking shootout, you'd probably be well served to take the under.
