If he makes the jump into the top 3 in the conference, I think we can expect great things next year.
He's top 3 in the conference almost guaranteed, at least to start the year. Just listing the QB's that either started last year or are projected to start puts him in the top 3 pretty much by default.
Stanford: KJ Costello - Imo 2nd best QB in the conference
Oregon: Justin Herbert - Obvious top QB in the conference
Oregon State: Conor Blount (most likely) - not even remotely close to a top 3 QB
Washington: Jacob Eason - did ok his Frosh year at Georgia but nothing that to me says top 3 quarterback. I'd maybe project him at 4 or 5
Wazzu: Anthony Gordon (no idea, just based on this years depth chart) - Unproven/unknown, statistically will probably be top 3 due to Leach offense, doubt he's true top 3
Cal: Chase Garbers - We all saw that offense, not a top 3 QB.
Colorado: Montez - my pick for 3rd QB in league
Utah: Huntley - dual threat guy, can throw but nothing stand out about him as a passer. #4 or 5 to me, interchangeable with Eason at this point.
UCLA: Thompson-Robinson - Athlete playing QB, not a 2017 Khalil Tate type player either, solid but not top 3.
USC: JT Daniels - the king of playing real life 500 with his receivers in games is not a top 3 QB by any means
Arizona: Khalil Tate - when he's not playing the Buffs, he's nothing special and he's probably going to be gone by next year any way.
Arizona State: Jayden Daniels or Joey Yellen - neither one is Trevor Lawrence special, not top 3.
If anything I'd move him to 4th but that's as low as he goes. PAC12 not a strong QB league next year.
