The Latest: Get ready for a new top 5 in college football's AP Top 25

No. 4 Alabama should take the greatest hit after a 23-21 loss to No. 11 Oklahoma.

The upset crushed not only the Crimson Tide’s eight-game winning streak, but also narrowed its path to the Southeastern Conference championship game and the College Football Playoff.

No. 3 Texas A&M nearly faced the same fate as the Tide. The Aggies had to pull off their biggest comeback in program history to beat South Carolina 31-30 and stay on track to play in the SEC title game.

No. 5 Georgia, meanwhile, is in for a promotion after its 35-10 win over No. 10 Texas.

Still solid are No. 1 Ohio State, which breezed through a victory over UCLA, and a still-undefeated No. 2 Indiana.

Who votes in the poll, and how does it work?

No organization has been ranking teams and naming a major college football national champion longer than The Associated Press, since 1936.

AP employees don’t vote themselves, but they do choose the voters. AP Top 25 voters comprise around 60 writers and broadcasters who cover college football for AP members and other select outlets. The goal is to have every state with a Football Bowl Subdivision school represented by at least one voter.

There is a 1-to-25 point system, with a team voted No. 1 receiving 25 points down to 1 point for a 25th-place vote. After that, it’s simple: The poll lists the teams with the most points from 1 to 25, and others receiving votes are also noted.

Voting is done online, and the tabulation is automated.
