re: All of this talk about Notre Dame's rushing defense

Notre Dames opponents averaged 158 yds per game. Notre dame held them to 92 yds. Thats a difference of -66. Alabama's opp averaged 163 yds per game. Bama gave 80 per game. A difference of -83 under their average. So no, Notre Dame did not do a better job of holding their opponents under their average.
