In the early part of the season, the rankings are based mostly on conjecture. Who is in and who is out when the preseason and Week 1 polls come out is based mostly on who has left the programs, who is replacing those who left and reputation.
As such, the rankings early in the season are quite volatile, and this season is no exception.
With five losses in the top 25 this week, these three teams could take the leap into the AP top 25.
Last week, Michigan was the leading vote-getter not to be ranked in the top 25. Coming off of a dramatic victory over Notre Dame, the Wolverines were the clear No. 26, finishing 27 points ahead of Southern Cal and 24 points behind Mississippi State, who is now 1-2 on the young season.
Michigan took care of business this week, knocking off Eastern Michigan 31-3 at home.
Their win over Notre Dame looks better now that Notre Dame has a win—a 31-13 upset over the No. 15 Michigan State Spartans.
Led by first-year coach Brady Hoke (pictured), U. Mich. could finally find itself back in the AP top 25.
The Trojans are banned from postseason play due to improper recruiting tactics and benefits given to players, but they can still be ranked in the top 25.
USC was No. 27 in the AP poll last week, finishing a step behind Michigan. They beat the Syracuse Orange, who earlier in the day filed the paperwork necessary to abandon the Big East, impressively, 38-17.
The Trojans moved to 3-0, and their three wins are all against FBS teams. Their Week 2 win over Utah is now more impressive, as Utah moved to 2-1 after pasting BYU 54-10.
Their Week 1 struggle with Minnesota did not seem to bother voters last week, so it should not effect them this week after USC's win over Syracuse. Finally blowing out a team will help USC in the eyes of voters, and should land USC in the top 25.
Clemson is a bit of a dark horse to reach the top 25 this week, but the Tigers should find themselves in the top 25 after their performance against No. 21, defending champion Auburn.
Although Auburn is a shell of what it was last year, they were still impressive in taking down a ranked Mississippi State team last week.
What was most impressive for Clemson, and should help them in the eyes of voters, was the way this week's game against Auburn played out.
Not only did Clemson pull out the upset, but the Tigers looked the better team much of the afternoon, and won going away, 38-24.
After Auburn jumped out to a 14-0 first quarter lead, Clemson outscored the Auburn Tigers 38-10, ending the 17-game win streak of Auburn.
Sophomore quarterback Tajh Boyd threw for 386 yards and four touchdowns, torching the Auburn secondary.
Clemson picked up a staggering 32 first downs while holding Auburn to 19 first downs.
Clemson may not be in the top 25 this week, but they should be.
