NCAA Football Power Rankings, Week 5

I've still got Auburn up at #1 after their win over Mississippi State, now #31. Last week's #2, California, lost to #9 Arizona State, and falls all the way to #11, and Boise State fell out of the #3 spot on bye. Ohio State enters playoff position, rising to #2 by beating Nebraska. SMU jumps up one spot to #3, winning against lowly South Florida. The last new playoff team this week is Clemson, up from #6 to #4, and notably still ahead of Alabama in my rankings.

18 undefeated teams remain as just 5 lost this week.

Missouri was on bye this week, but lost 13 spots because of other teams winning.

Akron took over the bottom spot by losing to otherwise-winless UMass, and Vanderbilt also won their first game, so we're down to 3 winless teams.
