The AP Top 25 College Football Poll is about to finally be rendered utterly useless when the College Football Playoff rankings show kicks off Tuesday, Nov. 4, but even with its final breaths of relevance it still found a way to be embarrassingly inaccurate.

The SEC and Big Ten both offered "College GameDay" an appetizing option or two for its Week 10 destination. In the SEC, the Oklahoma Sooners are in Knoxville to face the Tennessee Volunteers in a de facto College Football Playoff elimination game at Neyland Stadium (6:30 p.m. CT, ABC).

Memphis could also jump back into the top 25 after beating No. 20 USF, one of the top Group of Five contenders for the College Football Playoff. The Tigers fell out of the poll after Week 8 due to being upset by UAB. Illinois and Arizona State are also set to fall out of the rankings, after falling to Washington and Houston, respectively.

The top four seeds remain unchanged on the College Football Playoff bracket based on The Top 25 released Sunday, but three of the four first-round matchups would change and Memphis returned as the Group of Five representative.

Alabama heads into its second open week on a seven-game winning streak. Here's where the Crimson Tide sits in the latest college football rankings.

BYU remained unbeaten after defeating Iowa State 41-27. The No. 11-ranked Cougars improved to 8-0 and are still tied atop the Big 12 standings (5-0) with Cincinnati after overcoming a 14-point deficit in the first half.
