Notre Dame's defense let up in the 4th quarter which is why we needed Kizer's heroics in the first place. Zaire's first half was rough, but the drive before he left the game Zaire hit Fuller with the bomb TD and he had ND on the move at the time of his injury too. If he doesn't get hurt there, Notre Dame probably keeps its foot on the gas and even with BVG calling the defense it likely doesn't get close enough to matter.
