Pac-12 still fourth in conference rankings

ESPN Stats & Information still ranks the Pac-12 fourth in its Conference Power Rankings.

The Big 12 increased its lead over the SEC in the top spot. Six Big 12 teams are ranked in the AP Top 25 for the second-straight week. For the first time this season, the Big 12 has more teams ranked in the AP Top 25 (6) than the SEC (5) despite having two fewer teams in the conference.

The system used here equally weighs the rankings from The Associated Press Poll and a compilation of available BCS computer rankings in order to determine which conference is the strongest and weakest from top to bottom.

The Pac-12 gained a little ground ahead of the fifth-place ACC -- the margin increased to 5.9 points from 5.3 -- but lost ground to the No. 3 Big Ten, which increased its lead to nearly 13 points.
