A pair of top-10 teams from the SEC lost to unranked teams on Saturday, part of a day of upsets up and down the AP Top 25 poll that will reshape the new rankings on Sunday.

Chaos has arrived not only for college football down the stretch but also the outlook for the new top 25 rankings as well as the College Football Playoff picture could not be more unclear heading into the final week of the regular season.

Week 13 of the college football season continued to show that the Big 12 remains as compelling as any other conference in college football. And as a result, the Big 12's chances of having multiple bids to the 12-team College Football Playoff are in serious jeopardy after both of the conference's two top-ranked teams were upset on Saturday.
