Offense. I'd watched every game except their first and I never saw that sort of motion until Friday night. They looked more like a Pro-Style offense but over the bye week morphed into a spread/west coast motion heavy offense. Every single play they killed us on outside of the read option was a heavy dose of motion.
I believe the defense and Jay Hill were surprised by that. And there's no team who can replicate that sort of success the rest of the way.
I don't expect UCF to be moving three lineman in a pre-snap motion. Defense will be ready, offense is going to have a field day. 42-21 BYU
