How Week 4 Shook Up the NCAA Football Rankings
Week 4 of the college football season did more than produce a fresh set of scores. It reshaped the major rankings. Three systems moved in different ways, but the broad picture was clear: losses punished, wins rewarded, and Texas stayed at No. 1.
One loss can be costly
The Coaches Poll, released through CBS Sports, showed how quickly a single defeat can change a team's standing. USC plummeted after losing to Oregon. The report did not give an exact drop, but the direction was unmistakable. Iowa, by contrast, rose in the latest Coaches Poll.
At this point in the season, rankings are built on resumes. Week 4 is early enough that one result can carry unusual weight. A loss to a strong opponent can push a team down several spots, while a win over a credible opponent can boost a team just as quickly.
The AP Top 25 holds its line at No. 1
The Associated Press poll was steadier at the top. Texas stayed at No. 1 in the AP Top 25 after Week 4, according to Dallas News. The same report showed Texas A&M falling out of the rankings.
That contrast is a reminder that voters weigh more than wins and losses. They weigh who was beaten, how the game looked and what it means for the rest of the season. One team can hold the top spot while another drops out completely after a difficult week.
A computer's view of Week 4
ESPN's Football Power Index, covered by Yahoo Sports, also showed teams rising and falling after Week 4. FPI is not a human poll. It is a formula-driven ratings system, so its moves can look different from the AP and Coaches Polls.
FPI tends to respond to how a team plays, not just whether it wins. That makes it a useful counterweight to the subjective polls and a separate source of movement in the same week.
Together, these rankings show how fluid the college football picture is after the first month. Texas looks secure at the top. USC has to rebuild its case. Iowa has a reason to feel better about its position. Texas A&M has to work its way back. The week's results did not settle the season, but they set the terms for the next one.
