Pac-12 Pre-Season Positional Rankings: Offensive Line

1. David Yankey Sr. Stanford

Stanford has become an All-American offensive lineman factory and Yankey is the next guy in line. He's a big, tough, run blocker that will be on a lot of first team All-America teams and will likely be a first round draft pick after the season.

2. Hroniss Grasu Jr. Oregon

The Oregon offensive line is year after year one of the most underrated units in college football and Grasu is the best player on this season's version. Grasu made first team All-Pac-12 in 2012 as a sophomore and is a tough, athletic lineman that can run block and really move.

3. Xavier Su'a-Filo Jr. UCLA

Su'a-Filo came back from a mission and immediately made first team All-Pac-12 in 2012. Su'a-Filo paved the way for Johnathan Franklin to have one of the best seasons in Bruin history last season and also might be the best pass blocker in the conference.

4. Kevin Danser Sr. Stanford

Danser has great size for a guard at 6'6 300 and is a road grater that is a big part of the reason why the Cardinal have such a dominant run game. Danser is a savvy lineman that earned second team All-Pac-12 honors last season and has a good chance to make first team next season.

5. Cameron Fleming Sr. Stanford

Yet another beastly Stanford offensive lineman and Fleming might be the biggest of the bunch at 6'6 320. He's a monster in the run game at right tackle and earned honorable mention All-Pac-12 honors in 2012.

6. Jake Fisher Jr. Oregon

Fisher is a typical underrated Oregon offensive lineman that has size, speed, athleticism and knows how to work perfectly in their high-speed system.

7. Evan Finkenberg Sr. Arizona State

Finkenberg has started nearly every game of his career at Arizona State going into his senior year and earned honorable mention All-Pac-12 honors in 2012. Finkenberg is a great leader for the Sun Devils and paves the way for their dangerous run game.

8. John Martinez Sr. USC

The leader of USC's offensive line now with Khaled Holmes graduated, Martinez is going into his third season as a starter and was honorable mention All-Pac-12 as a junior.

9. Isaac Seumalo So. Oregon State

Seumalo was one of the most highly rated offensive linemen in the country coming out of high school and showed exactly why as a true freshman when he started for the Beavers at center last season. Seumalo has as much potential as any lineman in conference and I wouldn't be surprised if he leaves Oregon State as an All-American.

10. Grant Enger Sr. Oregon State

Enger teams with Seumalo and tackle Michael Philipp that is quietly one of the best in the conference. Enger made honorable mention All-Pac-12 last season, but is still one of the more underrated offensive linemen in the conference.

11. Daniel Munyer Jr. Colorado

Munyer is a bright spot on a Colorado line that has been relatively ineffective, especially in pass protection, but Munyer is a good run blocker who helped open up holes for Christian Powell and he earned honorable mention All-Pac-12 last season.

12. Tyler Johnstone So. Oregon

Johnstone blew up last season as a redshirt freshman and immediately became one of the best young offensive linemen in the conference. Like Fisher, Johnstone is a big, 6'6 guy who can really move and create holes in the running game.
