We don’t know everything about the makeup of Pac-12 rosters for the 2019-20 season — not even close to everything. But we know far more today than we did a week ago.

In fact, we know just about everything we can know until late May.

The top candidates to enter the NBA Draft have made their decisions. A few aren’t returning; many kept their options open and must finalize plans by the end of May.

The projections below are based largely on our best guesses and will be updated in early June. There’s a good chance the revisions will be significant.

And to clarify for readers: Under new rules, players can hire agents and still return to school.

1. Washington

Jaylen Nowell isn’t currently projected as a first rounder, so we’ll assume he returns for his junior season. Combine Nowell with 5-star big man Isaiah Stewart and incoming point guard Quade Green (a Kentucky transfer), and the Huskies would have a fabulous three-man core. Green isn’t eligible until the start of conference play, so UW’s performance in November and December could be lacking. But once the former 5-star settles in, watch out: UW will have the returning Pac-12 Player of the Year and two young mega-talents, plus complementary pieces like guard Nazhiah Carter. The Huskies should be the best team in the conference when it matters most.

2. Colorado

In contrast to the chaos elsewhere, the Buffaloes appear headed for a stable spring. All the key players are expected back for a program that was one of the hottest in the conference in the final month. McKinley Wright is one of the Pac-12’s top points guards and Tyler Bey one of the best big men. (And we know players improve from November to March under Tad Boyle.) If you’re looking for a comp for CU in 2020, consider Washington in ’19: The Huskies used all their returning production and experience as a catapult to the regular-season title. The Buffs just might do the same.

3. Oregon

The Ducks’ prospects dimmed a bit with the news that Kenny Wooten, Louis King and Payton Pritchard are testing the waters, for it’s unlikely that all three will return. We’re assuming Pritchard comes back but King and Wooten remain in the draft. (Jordan Bell’s success will boost Wooten’s stock, given the natural comparisons in skill and athleticism.) Pritchard is a fine foundation if he returns, but the Ducks will have to reload at multiple positions. They’re also in pursuit of several top uncommitted recruits; those decisions could alter this assessment.

4. USC

The Trojans lose their top talent (Kevin Porter) and their top scorer (Bennie Boatwright). But the mix of returning players, including big man Nick Rakocevic, top-20 recruits and transfers is impressive. In fact, this might be the deepest roster in the conference if Columbia transfer Quinton Adlesh is the impact player many expect. But the Trojans had all sorts of issues with consistency, chemistry and execution last season. Unless those get sorted out by coach Andy Enfield, the top-tier talent won’t be maximized.

5. Arizona

The toughest team in the conference to project because of the range of potential outcomes. In a best-case scenario, Sean Miller never takes the stand in the federal trial next week, the wiretap contents never become public, Miller remains as coach, the 5-star recruits (Nico Mannion and Josh Green) enroll as expected, other key pieces return, NCAA sanctions are limited or nonexistent, and the Wildcats return to the top of the conference. In a worst-case scenario, it all goes kaboom starting Monday: Miller gets fired, the recruits never set foot on campus, and the program is cast to the scrap heap for several seasons. We split the difference with this projection. It’s all TBD.

6. Arizona State

Th Sun Devils have several interesting pieces remaining but lose all-conference big man Zylan Cheatham and guard Luguentz Dort, creating significant holes in the lineup. Point guard Remy Martin’s progress as a steadying influence is vital, and the Sun Devils will need rising sophomore Taeshon Cherry to approach his potential. ASU’s range of landing spots in the standings is considerable, not because of their own roster turmoil but that of other contenders. If NBA decisions break poorly for Oregon and Washington, and if Arizona implodes, the Sun Devils could emerge from the wreckage as one of the teams to beat.

7. UCLA

We don’t know what the starting lineup or core rotation will look like, whether Moses Brown will return (and blossom), whether Tyger Campbell (knee) or Shareef O’Neal (heart surgery) will be top-tier contributors — few rosters in the conference pack as much uncertainty. But we know the Bruins will play better defense under new coach Mick Cronin than they have in many years. That alone should keep the program from free-falling until Cronin can rebuild the talent base. If a few returnees (for instance: guards Jules Bernard and David Singleton) emerge as impact players, the Bruins might improve on their seventh-place finish.

8. Utah

No program beats expectations more consistently than Utah, a testament to Larry Krystkowiak’s ability to fit his system around the modest talent. He’s facing the same challenge next season as the Utes lose top scorer Sedrick Barefield and zone-buster Parker Van Dyke. The forward tandem of Timmy Allen and Donnie Tillman will be one of the best in the conference — both were double-figure scorers — but help is required in the backcourt for the Utes to again make the Hotline look foolish.

9. Stanford

The Cardinal underachieved last season, finishing 10th in a bad league with a first-round pick on the roster. We’ll assume KZ Okpala stays in the draft, clouding the outlook for coach Jerod Haase’s fourth season. Count Stanford among the teams in dire need of better point guard play, thereby placing 4-star incoming freshman Tyrell Terry in the spotlight. If Terry helps settle the offense, the surrounding pieces (Daejon Davis, Oscar da Silva, Bryce Wills) might flourish, thus propelling Stanford into the middle of the pack.

10. Oregon State

Whither Tres Tinkle? One of the top players in the conference finished his fourth season and has entered the draft, albeit with the option to return for one last season with his father. We don’t pretend to have a sense for Tinkle’s lean, but if he departs, the Beavers will take a huge step toward the cellar. Guard Stephen Thompson is gone, and the three-man scoring machine will be reduced to one (Ethan Thompson). OSU’s fourth-place finish in ’19 might be as good as it gets in Corvallis for a long, long time.

11. Washington State

Kyle Smith inherits a ragtag roster that just might lose its top retuning player, C.J. Elleby, to the NBA Draft. We’re of the mindset that Elleby is (smartly) gauging his value at the next level but is likely to return. We’re also of the mindset that Smith’s analytics-based approach will make the most of the limited talent and avoid the cellar, thanks in large part to the presence of a program in even worse shape.

12. Cal

Lest we forget, the Bears were a No. 4 seed in the NCAAs just three years ago, then collapsed under the tenure of Wyking Jones. The man charged with clean-up duty, Mark Fox, is a sound coach will little to work with: Not a day passes, it seems, without another veteran entering the transfer portal. Alas, changing the culture — adding discipline and accountability and toughness — is just part of Fox’s considerable challenge. Check back in 2022 for an update on his progress.
