Pac-12 2013 Preseason Positional Unit Rankings: Offensive Line

1. Stanford (G David Yankey, G Kevin Danser, T Cameron Fleming, C Khalil Wilkes T Andrus Peat)

Jim Harbaugh and David Shaw have turned Stanford into an offensive lineman factory and this year's version is as good as any they have ever had. Yankey could be the best lineman in the country and Danser and Fleming are sure fire All-Pac-12 guys. Throw in Wilkes who was a solid starter at center last year and a host of other young talented guys waiting in the wings and the Cardinal are going to keep running people over in 2013.

2. Oregon (C Hroniss Grasu, T Jake Fisher, T Tyler Johnstone, G Mana Greig, G Hamani Stevens)

Year-after-year, this is on the most underrated and overachieving units in college football. The Ducks' bunch up front that leads the way to all their record-breaking rushing yards is usually kind of an anonymous gang, but Grasu made first team All-Pac-12 last year as a sophomore and is a potential All-American candidate. Fisher and Johnstone are guys who could definitely join Grasu as All-Pac-12 and can really move and the Ducks also have a ton of really good experienced depth to fill out the roster.

3. Oregon State (C Isaac Seumalo, G Grant Enger, T Michael Philipp, G Josh Andrews, T Gavin Andrews)

The Beavers unit up front needs to add a little bit of nasty, but they have a great balance of talent and experience. Seumalo is the best young lineman in the conference and could end up being the best center in the country by the time he leaves Corvallis. Enger is a standout returning starter and Philipp is a four-year starter that always has a lot of potential and this could be the year that he completely fulfills it.

4. USC (G John Martinez, G Max Tuerk, T Kevin Graf, T Aundrey Walker, C Marcus Martin)

A nice mix of young talent and solid experience, the Trojans have a line loaded with former big time recruits who just quite haven't lived up to expectations. Martinez and Graf are good seniors that have been around for a while Tuerk is up there as one of the most promising young linemen in the conference. The group is finished off with two very good juniors in Walker and Martin.

5. Arizona (T Fabbians Ebbele, G Chris Putton, T Mickey Baucus, G Cayman Bundage, C Jacob Arzouman)

Ka'Deem Carey has a good line to run behind this year. Anchored by two massive, experienced tackles in Ebbele and Baucus, the Wildcats have great size up front and some experience, especially with senior standout Putton.

6. Arizona State (T Evan Finkenberg, C Kody Koebensky, T Jamil Douglas, G Sil Ajawara, G Vi Teofilo)

Finkenberg, who could sneak into first team All-Pac-12 is the senior leader here and the rest of the bunch are fairly experienced players who will be blocking for two good running backs in Marion Grice and D.J. Foster.

7. UCLA (G Xavier Su'a-Filo, C Jake Brendel, T Torian White, T Simon Goines, G Caleb Benenoch)

UCLA gave up a ton of sacks last season and lost a lot of experienced, but still have one of the best linemen in the conference in Su'a-Filo, who was All-Pac-12 as a sophomore last season. Brendel was great at center as a freshman, but this unit needs to shore up its pass blocking and will rely on a lot of very young players.

8. Utah (T Jeremiah Poutasi, C Vyncent Jones, G Jeremiah Tofeono, G Junior Salt, T Siaosi Aiono)

Poutasi had a great season as a freshman last season, but the rest of the unit here is unproven and the Utes don't have a good proven running back so they will need to open up some holes if they hope to have any kind of running game.

9. Cal (G Jordan Rigsbee, G Chris Adcock, T Bill Tyndall, T Freddie Tagaloa, C Matt Cochran)

The Bears always seemed to have good lines under Jeff Tedford and could reload whenever they graduated good players but we'll see if they will be able to do that under Sonny Dykes.

10. Washington (T Ben Riva, G Dexter Charles, T Micah Hatchie, G Mike Criste, C Erik Kohler)

The Huskies return four starters from last season here, but it seems like they return an experienced line every year, but it struggles. The Huskies have no particular standouts here and the unit really needs to improve their pass blocking from last season.

11. Washington State (C Elliott Bosch, T Gunnar Eklund, G John Fullington, T Rico Forbes)

Bosch is a good anchor at center, but the rest here is a mess and there is a good chance that the Cougars will have to rely on walk-ons heavily. Also, Mike Leach's offense may be all about passing, but these guys are going to have to find a way to get some kind of run game going in 2013.

12. Colorado (G Daniel Munyer, T Jack Harris, T Stephane Nembot, G Kaiwi Crabb, C Gus Handler)

Munyer made honorable mention All-Pac-12 last season and Harris and Nembot are returning starters too, but there's no other reason to think that Colorado's line will be anything but one of the worst in the conference yet again.
