- Justin Herbert Sr. Oregon - It’s time for Herbert to fulfill his potential and become the Heisman candidate, game changer he has the potential to be. Well, he’s still probably the conference’s best QB going in even if he doesn’t progress into that.
- KJ Costello Sr. Stanford - You could easily make a case that Costello was better than Herbert in 2018 so don’t be shocked if he’s better in 2019. Costello puts up decent stats for a good team and is a gamer with major NFL potential.
- Jacob Eason Jr. Washington - Eason is one of the hardest to peg players in the nation coming into 2019. He has the arm and potential of a top overall draft pick for 2020, but he hasn’t even fully won the job at Washington yet. I think he does and is at least pretty good in 2019.
- Gage Gubrud Sr. Washington State - Speaking of impossible to peg transfer signal callers in the Evergreen State, a lot of signs point to the Eastern Washington grad transfer picking up where Gardner Minshew left off. When was the last time a Mike Leach quarterback wasn’t pretty effective?
- Tyler Huntley Sr. Utah - Huntley looked like the difference maker at QB Utah needed to win the conference before he got hurt in 2018. He’s a game that doesn’t have the raw tools the guys ahead of him have on this list so it limits his preseason hype, especially as he overcomes an injury.
- Khalil Tate Sr. Arizona - Tate’s fall from grace has been well-documented by Pac-12 fans and maybe a bit exaggerated at this point. He’s still a dangerous QB and one that should frustrate Pac-12 defenses in 2019.
- Steven Montez Sr. Colorado - Like Sefo Liufau before him, Montez is a multi-year starter at Colorado who is big and mobile with a big arm that hasn’t pushed the Buffs, or himself to the next level. He’s still a dark horse candidate to have a breakout as a senior just like Liufau did.
- JT Daniels So. USC - USC’s new golden boy actually has a lot of potential in my opinion, it’s just the conference is loaded with good, proven seniors, so he’s going to have to have a very big year to jump over them. He’s capable of it though in USC’s new offense.
- Dorian Thompson-Robinson So. UCLA - I might like DTR more than Daniels actually. He’s mobile, accurate, and should only continue to grow in Chip Kelly’s system. I could see him moving up this list as the season goes on.
- Chase Garbers So. Cal - Garbers had a rough 2018 as he and the Cal offense held back a scary good Cal defense and he split some time with another quarterback that seemed to specialize in back-breaking interceptions. The good news is sounds like held off UCLA transfer Devon Modster in Spring and might be taking a step forward.
- Jake Luton Sr. Oregon State - The Pac-12’s biggest quarterback with one of its biggest arms should win the job again in Corvallis. I see him being at least solid as long as he’s healthy in 2019.
- Dillon Sterling-Cole Jr. Arizona State - It sounded like DSC beat out Jayden Daniels in Spring and I think has a great shot to start at least at the start of the season. He has massive potential and could quickly get to Manny Wilkins’ level.
