Ollie missed a couple of cutbacks on inside zone in the 2nd quarter. It looks like an adjustment that was made was to emphasize that OL movement later in the game (see his third touchdown)
Dunn HAS to be able to find a way to run the ball effectively, and it will likely involve some window dressing and a lot of movement, and maybe something they haven't seen yet.
And as many have said, Bowman will have to pass to open up the run. BYU gradually moved their safety back a few steps in the 3rd and 4th quarters as Bowman continued to hit LJ3 on the skinny post right over them.
