Zion Williamson is a huge talent, but hardly the only intrigue or storyline in Thursday’s NBA draft at Barclays Center.

Will the Knicks hold onto the third pick, and if so, will they take RJ Barrett as expected or Darius Garland? After the Pelicans got the No. 4 pick in the Anthony Davis deal, do they trade it away for a veteran?

The Hawks and Celtics each have three first-rounders, and are looking to make a late deal, like Memphis did in unloading veteran Mike Conley on Wednesday. What moves will they make, and what will the Nets come away with picking at No. 27 and again at No. 31?

1. New Orleans Pelicans

Zion Williamson

Duke, F, 6-7, 272

A generational talent. The most-hyped prospect since Anthony Davis, the star he’ll replace as the face of the Pelicans. This no-brainer pick takes as long as it takes David Griffin to sprint over and hand in the envelope.

2. Memphis Grizzlies

Ja Morant

Murray State, PG, 6-3, 175

An electrifying talent with legit star potential. Bouncy, with great vision and tons of upside, he allowed the Grizzlies to go out and turbo-charge their rebuild by trading Conley to Utah for a king’s ransom.

3. New York Knicks

RJ Barrett

Duke, SG/SF, 6-7, 202

After reports that the Knicks turned down Atlanta’s offer of picks No. 8 and 10 for this spot, expect them to stand pat. They hosted Garland in a last-minute workout Wednesday, but expect them to take Barrett, a prototypical wing who seems born for the Garden spotlight, with a dad who played at St. John’s and a mom from Brooklyn.

4. New Orleans Pelicans

De’Andre Hunter

Virginia, SF/PF, 6-7, 225

Griffin has been shopping this pick since he got it, with the Timberwolves, Celtics and Bulls reportedly interested. But if they don’t move it for a veteran, Hunter is a good pick with his versatile defense and 43.8 percent shooting from deep.

5. Cleveland Cavaliers

Darius Garland

Vanderbilt, PG, 6-2, 175

He can create, he can shoot off the dribble … but can he co-exist with Collin Sexton? That’s the job of John Beilein, who’ll have a host of young players and has to get them in sync with his system.

6. Phoenix Suns

Jarrett Culver

Texas Tech, SG, 6-6, 195

Phoenix is still searching for a veteran point guard, either via trade or free agency. They could deal the pick for one, but if they stand pat, Culver could be the best-available.

7. Chicago Bulls

Coby White

North Carolina, PG/SG, 6-5, 185

Chicago has a solid frontcourt, and is probably a point guard away from making the playoffs. White could be that player, if he learns to distribute and play under control. Roy Williams gushes over him.

8. Atlanta Hawks

Cam Reddish

Duke, SF, 6-8, 218

The Hawks tried to package this and move up to the Knicks’ No. 3 pick. If they don’t find a trade partner, Reddish looks like a nice wing replacement for Taurean Prince, whom they traded to the Nets.

9. Washington Wizards

Brandon Clarke

Gonzaga, PF, 6-8, 215

Even if the Wizards are intent on holding onto Bradley Beal — ESPN reported they could mull a three-year, $111 million extension — this is a long rebuild after John Wall’s injury. Sekou Doumbouya would be bold, but Clarke is safer and a proven defender for a team that needs that.

10. Atlanta Hawks

Goga Bitadze

Georgia, C, 6-11, 245

Despite John Collins’ presence, Atlanta can use more big men. Bitadze can play center and also hit from outside, so they should give the Hawks some flexibility if they can’t move up to No. 3 or 4.

11. Minnesota Timberwolves

Sekou Doumbouya

France, PF, 6-9, 230

Doumbouya could have top-10 talent. He’s raw — expected for a French prospect who didn’t start playing until he was 12 — but the upside is tantalizing for a Timberwolves team with a brand-new regime.

12. Charlotte Hornets

Jaxson Hayes

Texas, C, 6-11, 220

The Hornets’ offseason is all about whether Michael Jordan can open up the vault enough to keep Kemba Walker. But the Big 12 Freshman of the Year would be a great piece to add, with or without Walker.

13. Miami Heat

Darius Bazley

Princeton HS (Ohio), SF, 6-9, 205

Miami banks on its culture and player development. Kevin Porter Jr. could be tempting here, but the Heat go for Bazley, who skipped college to spend last year training on the advice of agent Rich Paul. He worked out Tuesday for the 76ers, raising questions of a first-round promise.

14. Boston Celtics

Nassir Little

North Carolina, SF, 6-6, 220

The Celtics pick No. 14, 20 and 22, and don’t want to make them all. But if they stand pat, a good choice could be Bol Bol or Little, who was inconsistent at UNC but was the MVP of both the McDonald’s All-American and Jordan Brand games.

15. Detroit Pistons

Rui Hachimura

Gonzaga, SF/PF, 6-8, 230

He’s got the production, the experience and the wingspan at 7 feet 2 to slot in as part of an imposing frontcourt.

16. Orlando Magic

Tyler Herro

Kentucky, SG, 6-5, 195

He can shoot off the dribble and hit over 40 percent from deep. If Markelle Fultz can get right, they can give the Magic much-needed perimeter help, especially if they lose Terrence Ross.

17. Atlanta Hawks

PJ Washington

Kentucky, PF, 6-8, 228

It seems unlikely the Hawks make all three of their first-round picks. But if they keep this one — received from the Nets — Washington is a solid as a stretch four.

18. Indiana Pacers

Keldon Johnson

Kentucky, SG, 6-6, 211

The Pacers could use a point guard, but with Victor Oladipo out for much of next season, an off-guard of Johnson’s ability could provide some valuable minutes.

19. San Antonio Spurs

Kevin Porter Jr.

USC, SG, 6-6, 218

If there’s a team that can rely on its culture to help Porter, it’s San Antonio. Despite a questionable approach and off-court issues, that lottery-worthy talent is worth a flier at this point in the draft.

20. Boston Celtics

Romeo Langford

Indiana, SG, 6-6, 215

The latest Indiana schoolboy legend shot poorly last season, but he played through a torn thumb ligament. Toughness, a 7-foot wingspan and rebounding ability could make him attractive.

21. Oklahoma City Thunder

Cam Johnson

North Carolina, SF, 6-9, 210

A savvy offensive player who might be the best shooter in the whole draft, at over 45 percent from deep.

22. Boston Celtics

Bol Bol

Oregon, C, 7-2, 208

If the Celtics make this pick, Bol is too good to pass up, with a 7-2 wingspan and hitting 52 percent from deep. If he can pack on some pounds, he’s a top-10 talent.

23. Memphis Grizzlies

KZ Okpala

Stanford, SG, 6-9, 215

Oozes upside. Could make a nice running mate for Morant in an athletic young backcourt.

24. Philadelphia 76ers

Matisse Thybulle

Washington, SG, 6-5, 200

The Sixers already needed shooting and guard depth, and Jimmy Butler and JJ Redick are free agents. Thybulle brings defense, athleticism and some insurance at off-guard.

25. Portland Trail Blazers

Mfiondu Kabengele

Florida State, F/C, 6-10, 250

Portland center Jusuf Nurkic sustained compound fractures to his left tibia and fibula against the Nets on March 25, and there’s no telling when he’ll be 100 percent. Any early minutes Kabengele gets will help accelerate his growth into a viable backup.

26. Cleveland Cavaliers

Nickeil Alexander-Walker

Virginia Tech, SG, 6-6, 205

With a second first-round pick, the Cavs could go for a wing like Louis King or a rim protector like Tacko Fall. But Alexander-Walker is the best available. Think of him as a young Spencer Dinwiddie type.

27. Brooklyn Nets

Luka Samanic

Croatia, PF, 6-10, 215

The Nets’ last three draft picks have been Europeans 6-9 or taller. Expect them to stay on brand, especially considering their need at stretch-four. The Croatian is skilled, versatile, coming off a great game at the NBA combine and — like Dzanan Musa last year — wants no part of being a stash and plans to come over next year.

28. Golden State Warriors

Luguentz Dort

Arizona State, SG, 6-4, 215

Let’s be fair: Right now Warriors fans are thinking about keeping Kevin Durant and Klay Thompson. But with both injured, even if they re-sign, the Warriors can use perimeter help like Dort.

29. San Antonio Spurs

Louis King

Oregon, SF, 6-9, 205

San Antonio could use another wing, and King is the best on the board.

30. Milwaukee Bucks

Ty Jerome

Virginia, PG/SG, 6-5, 195

The Bucks are all about length and athleticism, but Jerome is a smart winner who gets buckets.
