There are highs and lows every week in college football. The winners and losers for Week 4 start with Southern California's loss to Michigan.

As a result, Michigan rose in the Week 5 US LBM Coaches Poll, moving from No. 17 to No. 12. Former opponent Texas is ranked No. 3, and future opponents also found themselves ranked: Illinois is No. 21, Oregon is No. 7, and Ohio State is No. 3.

Since opening the season ranked No. 9 in the Associated Press' Top 25 poll, Michigan had dropped for three consecutive weeks following unimpressive victories over Fresno State and Arkansas State, and a 31-12 loss to Texas.
