How about the non-call in the first half when the NC player (Noel?) got hit in the eye and the ball came loose? I know NC recovered and it had little bearing on the game, but smacking someone in the face is hardly incidental contact. I was surprised this wasn't called, since the player still had the ball. Usually you see this type of thing missed after the player gets rid of the ball.
I guess they figured the Illinois player hit the ball.
Either that or the face is part of ball.
