Adams collected a sack in his eighth consecutive game Saturday to regain his status as the No. 1 defensive lineman in the power rankings, which measure the nation's best players and coaches at each position.
The Clemson senior had taken over the top spot two weeks ago after recording a sack in the Tigers' 31-7 victory over Georgia Tech. Woodley replaced him last week when he compiled a pair of sacks for the third consecutive game.
Woodley's streak ended last weekend when he made just one solo tackle and failed to deliver a sack in Michigan's 34-26 triumph over Ball State. That allowed Adams to move back in front, even though his team fell 13-12 to Maryland for its second consecutive loss.
This also marked the second week in a row that a Pac-10 player zoomed to the top of the special-teams charts.
Last week, Oregon State's Sammie Stroughter took over the No. 1 spot after scoring on a 70-yard punt return in a 33-31 upset of Southern Cal. California's DeSean Jackson moved atop the list this week following a 72-yard punt return in the Golden Bears' 38-24 victory over UCLA.
Jackson and Stroughter both have returned three punts for touchdowns this season. Jackson is averaging 17.2 yards per return, while Stroughter is gaining 16.9 yards per return.
Peterson remains atop the power rankings despite breaking his collarbone because of the possibility that he could return in time for a bowl game. Players who suffer season-ending injuries are automatically removed from consideration.
The rating of a player and coach can fluctuate each week depending on how they fared the previous Saturday, but the power rankings measure their overall careers as well as their most recent performances.
For example, Smith threw for just 108 yards and an interception in Ohio State's 17-10 victory over Illinois last weekend. Notre Dame's Brady Quinn threw for 346 yards and four touchdowns in a 45-26 win over North Carolina.
Quinn certainly had the better game Saturday, but Smith remains atop our quarterback rankings because we feel the Ohio State senior is having the better year.
By the end of the season, our power rankings should provide an accurate indicator of which players and coaches were the best at their respective positions.
