Just one week left in the Pac-12 football regular season and only four teams remain in contention for the conference championship. Below is a look at the penultimate Pac-12 Power Rankings for 2016:
1. USC Trojans (8-3, 7-2)
Last week: def. UCLA, 36-14
Previous ranking: 1
From a horrendous 1-3 start to seven straight wins for the Trojans, who followed up their upset of Washington with a second consecutive win over rival UCLA. USC still has a shot at a Pac-12 title game berth, if Utah can upset Colorado.
