Pac-12 still fourth in conference rankings

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

The Big 12 remains No. 1 over the SEC, even though LSU eclipsed Oklahoma in the AP poll.

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

Last week, the No. 3 Big Ten, Pac-12 and No. 5 ACC were separated by just 2.4 points. This week, the Big Ten increased its margin ahead of the Pac-12 by nearly eight points.

In fact, the Mountain West is gaining on both the Pac-12 and ACC. It's just 0.6 points behind the ACC and 3.6 points behind the Pac-12.
