BYU just needs to play their game. Play a solid defense and avoid huge mistakes. I'm hoping to see a little more from the offense — mainly third down conversions and keeping the drive alive (if for no other reason than to give the D a rest and flip the field).
I've watched Kalani's BYU teams beat Michigan State, USC, Wisconsin, Tennessee, Baylor - day games. And get blown out by ISU and OK St. in night games last year. The OU game was at 10 and BYU was in the driver's seat until the 100 yard pick six.
