- Stanford (T Walker Little So. G Nate Herbig Jr. C Jesse Burkett Sr. G Brandon Fanaika Sr. T A.T. Hall Sr. G Foster Sarell So.) This isn’t the level of the great offensive lines of yesteryear in Palo Alto, but it’s a very good one. This group came together last year and returns almost every starter, including first-team All-Pac-12 guard Herbig and 6’8 future All-American Little.
- Washington (T Trey Adams Sr. G Luke Wattenberg So. C Nick Harris Jr. G Henry Roberts Jr. T Kaleb McGary Sr.) The Huskies are right there with Stanford led by two 6’8 tackles who are the best at their position in the conference. The interior of the line is a slight question, but Harris is a veteran and one of the best run blockers in the conference.
- Oregon (T Brady Aiello Jr. G Calvin Throckmorton Jr. C Jake Hanson Jr. G Shane Lemieux Jr. T Jacob Capra So.) The Duck offensive line has grown up in two years from when the starting unit was almost entirely freshman. Starting those youngsters has paid off as the Ducks now have a seasoned offensive line filled with players who could be All-Pac-12 in 2018.
- USC (T Chuma Edoga Sr. G Andrew Voorhees So. C Toa Lobendahn Sr. G Chris Brown Sr. T Clayton Johnson Jr.) This group is talented and experienced at a few spots with Brown, Edoga, and Lobendahn being multi-year starters. Lobendahn could be the key as he has star potential if he can stay healthy, but has just always been hurt throughout his career.
- Utah (T Jackson Barton Sr. G Alani Havili-Katoa Sr. C Lo Falemaka Sr. G Jordan Agasiva Sr. T Darrin Paulo Jr.) The Utes have a lot of size and talent up front. Barton and Paulo is one of the best tackle combos in the conference and the interior group isn’t far behind.
- Washington State (T Andre Dillard Sr. G Noah Osur-Myers Jr. C Frederick Mauigoa Jr. G Robert Valencia Sr. Liam Ryan So.) Dillard is one of the best linemen in the conference, but the rest of the group has to do a little reloading after losing a group of starters including Cody O’Connell and Cole Madison.
- Colorado (T Isaac Miller Jr. G Josh Kaiser Sr. C Tim Lynott Jr. G Brett Tonz Jr. T Aaron Haigler Jr.) Lynott is quickly becoming one of the conference’s best offensive linemen and the talent around him is a lot better than it was a few years ago. This is a solid unit.
- UCLA (T Jake Burton So. G Michael Alves So. C Josh Wariboko-Alali Jr. So. T Andre James Jr.) This is probably one of the most-talented groups in the conference, but the Bruins have been a massive disappointment on the offensive line the past couple of years. This group could easily be in the top four, but they have a lot to prove.
- Arizona State (T Cohl Cabral Jr. G Steven Miller Jr. C Quinn Bailey Sr. G Connor Humphreys Sr. T Zach Robertson Jr.) This is a pretty good group for being ranked ninth. There’s plenty of talent and experience, it just needs to prove itself in 2018.
- Arizona (T Layth Friekh Sr. G Alex Kosinski Jr. C Nathan Eldridge Jr. G Michael Eletise So. T Cody Creason Jr.) Eldridge has All-Pac-12 talent in the middle and Friekh has a ton of experience. The Wildcats aren’t loaded with talent on the offensive line, but they might not need to be with Khalil Tate’s ability to make plays on his own.
- Cal (T Patrick Mekari Sr. G Kamryn Bennett Sr. C Addison Ooms Sr. G Valentino Daltoso So. T Jake Curhan So.) Justin Wilcox has quickly improved Cal, but he still has some work to do on the offensive line where they have one of the least-impressive units in the conference going into the season.
- Oregon State (T Blake Brandel Jr. G Gus Lavaka Jr. C Sumner Houston Sr. G Trent Moore Sr. T Clay Cordasco Jr.) The Beavers need to improve at pretty much every position across the board. I will say they have a decent amount of potential here though, especially at guard with Lavaka.
