Pac-12 Top 25 for 2013: No. 10

Our countdown of the Pac-12’s Top 25 players from the 2013 season continues.

You can review our 2013 preseason Top 25 here.

No. 10: Leonard Williams, DE, USC

2013 numbers: Williams was second on the Trojans with 74 tackles, tied with Devon Kennard for the team-lead with 13.5 tackles for loss and forced two fumbles.

Preseason ranking: unranked

Making the case for Williams: Then interim coach Ed Orgeron thought enough of Williams to predict the defensive end would eventually become a first-round pick and called him the best defensive lineman he's ever coached. On the list of semifinalists for the Chuck Bednarik Award, given to the nation's top defensive player, Williams was the lone sophomore. The Florida native was one of three Pac-12 players named to ESPN.com's All-America Team.
