After a one-year lull, the collective might of the Pac-12 North returned to grab the league's balance of the power from the Pac-12 South.
The North finished 2015 with a 15-10 record in its head-to-head matchups with the South, marking the fourth time in five years since expansion that the division has held the final advantage. The South won the head-to-head by a 15-10 tally last season, but the tumbles of both Arizona schools -- coupled with the resurgence of Stanford and the rise of Washington State in the North -- shifted the advantage back the other way.
