What a difference a week makes in college football. At this time last week, the juggernaut that is Wake Forest led the nation in total defense. One week later, though, the Demon Deacons have tumbled to No. 12 overall.

Our No. 1 defense last week, Alabama, had the week off. Where will they rank this week? They have a tough test this weekend against Johnny Manziel and Texas A&M in College Station.
