They dominated the total yards stat, but lets not act like they were moving downfield 10 yards at a time. Over a 120 rushing yards, but just 2.8 YPC. They were forced to throw it and we saw what happened there.
The "total yards" domination is a bit deceiving. At least 60 of their 200 yard margin over UM was in garbage time-- when the score was 21-9 with 3:30 to play. They marched right down the field and scored a td when the UM had 10 players on the field. I'm not saying that they didn't significantly outgain UM, but it wasn't by as much as they want you to believe.
