UCF used much more finesse to run the ball including the QB and wildcat. The did many off tackle.
Utah is not about finesse. Third or fourth and short they don't hide it. They're going to run straight dive between the tackles. This has been a problem for BYU DL. BYU 3-4 is out muscled in the box especially if they use 12 or 22 personnel. This will be a very tough task. I expect Utah to play jumbo ball to ram the ball down BYU like Stanford did with Harbaugh. BYU hasn't faced an offense like Utah. This is the biggest game of the year for them
