Pac-12 Top 25 for 2013: No. 9

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. 9: David Yankey, OG, Stanford

2013 numbers: Yankey was the leader of an offensive line that ranked No. 7 in the country in allowing just 4.14 tackles for loss per game and No. 11 for fewest sacks per game (1.14).

Preseason ranking: No. 9

Making the case for Yankey: The eighth unanimous All-American in Stanford history, Yankey was was three-year fixture on the Cardinal offensive line. He rotated between left tackle and left guard a year ago, but lining up at guard full time this season Yankey solidified his reputation as one of the nation's top pulling guards. He helped pave the way for 1,700-yard back Tyler Gaffney and decided to forgo his final year of eligibility to enter the NFL draft. ESPN Scouts Inc. ranks Yankey as the draft's fourth-best offensive guard.
