Today, Rivals.com completes its 2008 countdown, releasing the preseason ranking of the Division I-A teams from No. 120 to No. 1.

We started at the bottom in groups of 10, then moved to a daily countdown from 50th to first, with our No. 1 team - Southern California - unveiled July 31.

Now, you won't see any college team rankings from Rivals until early October. The reason: We will wait until enough games have been played so we can legitimately rank the teams.

The rankings were compiled by football writers Olin Buchanan, Tom Dienhart, David Fox, Mike Huguenin and Steve Megargee. They look forward to your e-mails and your comments on the message boards.

Auburn hasn't won the SEC West since its undefeated season of 2004, but that could change in '08. Despite a new QB and two new coordinators, the Tigers the talent. Read the full preview
