Here's what to keep an eye on Saturday when the Irish host the Owls.
1. Running backs: William Mahone is out with an ankle sprain, but five other backs will get the chance to make plays Saturday, starting with George Atkinson III. Seeing how often, and how well, the offense runs the pistol is also noteworthy.
2. Jaylon Smith: The five-star freshman will likely start from Day 1, giving all a glimpse of what made him such a prized prospect and what allowed him to ascend up the depth chart so quickly in camp.
3. Defensive depth: If there were ever a game on Notre Dame's schedule to figure out what it has down the depth chart, especially on the increasingly thin defensive line, this is it. And not just because of the expected heat. Keep an eye on fresh faces Cole Luke and Max Redfield in the secondary.
