And away we go ... starting, of course, with quarterback.
Oregon: Junior Marcus Mariota is -- again -- a leading Heisman Trophy candidate and a two-time first-team All-Pac-12 performer. He would have been an early-round NFL draft pick this spring if he'd opted not to return. The Ducks have some questions at receiver though.
UCLA: Junior Brett Hundley is the conference's No. 2 Heisman Trophy candidate. While Arizona State's Taylor Kelly eclipsed him for second-team All-Pac-12 last fall, Hundley's tremendous upside is why he has NFL scouts eagerly awaiting his entering the draft.
Arizona State: As noted, Kelly was the Pac-12's No. 2 QB last season, which means he was one of the nation's best at the position. It also helps his cause that he's got WR Jaelen Strong, an All-American candidate. However, Kelly does need to take fewer sacks -- you could say the same for Hundley -- and throw fewer interceptions.
Oregon State: Sean Mannion ranked second in the nation with 358.6 yards passing per game in 2013 and is also an NFL prospect. Life might be just a bit harder in the passing game without Brandin Cooks.
Stanford: Kevin Hogan, a third-year starter, had a good but not great sophomore season while leading the Cardinal to the Pac-12 championship. He was mostly efficient and showed a good touch downfield, but he made some surprisingly bad decisions and needs work with his intermediate passing game. He's got a good crew of veteran receivers coming back, which bodes well for him.
Washington State: Connor Halliday threw for a bunch of yards (4,597) and TDs (34) last season, but he also tossed way too many interceptions (22). Part of that was an inconsistent O-line and a neglected running game. The good news is he's in his third year under Mike Leach and has a strong crew of returning receivers. Of all the Pac-12 QBs, he might make the biggest climb this season.
USC: Cody Kessler didn't put up big numbers last season and didn't beat Notre Dame or UCLA but significantly improved after Lane Kiffin was fired. Like Kelly, he's got an A-list target coming back in WR Nelson Agholor. We expect Kessler to thrive with a new, up-tempo scheme under Steve Sarkisian.
Utah: Utah received good news yesterday when 16-game starter Travis Wilson was medically cleared to play. When healthy, Wilson has been a solid performer with good upside. He'll have to fight off a challenge this preseason from Oklahoma transfer Kendal Thompson though.
California: Jared Goff averaged 292 yards passing per game as a true freshman. That's good. But the Cal offense struggled to do much else but throw the ball between the 20s -- hence a conference-worst 23 points per game. He had just 18 TD passes on 531 attempts. Still, he flashed potential and has a very good crew of receivers coming back.
Colorado: Sefo Liufau became the Buffaloes' starter at midseason and often played like the true freshman he was. Furthermore, he won't have Paul Richardson serving as a safety blanket and making big plays for him. Still, Liufau's baptism by Pac-12 fire provided some seasoning that was evident this spring. The Buffs feel pretty good about having a returning starter behind center.
