Update (April 24): The Big Board has been updated to reflect the news that Ivan Rabb, Grayson Allen and Thomas Bryant will not be entering the 2016 draft.
The NCAA tournament rearranged the draft rankings, with explosive performances from Buddy Hield and the news that Thon Maker is declaring for the draft. So it's time for a new Big Board.
Our board has the latest intel on how NBA teams see the top NBA prospects, based on conversations with general managers and NBA scouts.
1. Ben Simmons
Previous rank: No. 1
LSU
Freshman
Forward
Simmons' lack of NCAA tournament play certainly didn't help his cause. It's rare to see a potential No. 1 pick not in the tourney.
Simmons still remains on top of most NBA draft boards, but he has some serious questions to answer when he goes into workouts.
His lack of a jump shot has been on the minds of scouts all year. But now the bigger question appears to be: Does Simmons have the drive it takes to be superstar? His uninspired play down the stretch left room for doubt.
To remain the top pick, he's going to have to provide some persuasive answers.
2. Brandon Ingram
Previous rank: No. 2
Duke
Freshman
Forward
Ingram's strong play in the tournament strengthened his claim that he, not Simmons, is the best prospect in the draft.
He was Duke's best player during the tourney until the last 11:50 of the Oregon game, when he didn't score another field goal. Concerns about Ingram's strength -- and some questions about exactly how good a 3-point shooter and athlete he is -- are the biggest reasons he hasn't overtaken Simmons for No. 1 in the rankings for most NBA teams.
3. Dragan Bender
Previous rank: No. 3
Croatia
Age: 18
Forward/center
Bender has been getting more minutes of late for Maccabi Tel Aviv, and he's made the most of them.
For the season Bender is shooting 45 percent from the 3-point line. That's extremely appealing for team looking for bigs who can both stretch the floor and protect the rim.
While the jury's still out on just how good he is, the consensus among most NBA front offices is that after Simmons and Ingram are gone, he's the guy.
4. Jamal Murray
Previous rank: No. 8
Kentucky
Freshman
Guard
Murray started out at No. 5 when Big Board 1.0 was released in July, and now he moves up to his highest spot ever.
There are concerns about his athletic explosiveness and whether he can make the transition to point guard. But his shooting, basketball IQ and leadership on the court have most scouts convinced he'll have a shot at being an All-Star someday.
5. Buddy Hield
Previous rank: No. 9
Oklahoma
Senior
Guard
After Hield lit up Oregon for 37 points in the Elite Eight, the question became, "Is Buddy a top-five pick?" Some went further to ask about the top three.
For the most part, he had a scintillating tournament. But his poor performance against Villanova in the Final Four brought some reality back into the equation.
He's an outstanding shooter, but he isn't Stephen Curry. That said, with the Celtics, Timberwolves, Pelicans and Kings all looking for shooting, he's looking more and more like a lock to go in the No. 4 to No. 7 range.
6. Henry Ellenson
Previous rank: No. 4
Marquette
Freshman
Forward/center
Ellenson's team missed the tournament, keeping him from showing off his considerable skills. He's a good athlete who can shoot, rebound and score in the paint.
While his jump shot was streaky, Ellenson and Bender are the players most NBA scouts see as the top stretch-4s in this draft.
7. Kris Dunn
Previous rank: No. 5
Providence
Junior
Guard
Dunn played two strong games in the tournament and a hot shooting streak (he was 7-for-10 from deep against USC and North Carolina) boosted his 3-point shooting percentage to 37 percent on the year. Turnovers remained a weakness for him.
8. Marquese Chriss
Previous rank: No. 14
Washington
Freshman
Forward
Chriss continues to rocket up our board. After Washington missed the NCAA tournament, Chriss put up several strong games in the NIT, including a 27-point, 11-rebound performance against Long Beach State and 19 points against San Diego State.
He's a high-risk, high-reward player, but after Simmons and Ingram (and possibly Bender), I'm not sure there's a player in the draft with more long-term upside.
9. Jaylen Brown
Previous rank: No. 6
Cal
Freshman
Forward
Brown looks the part of an NBA lottery pick, but a horrific slump during the last five games of the season had him shooting 10-for-48 from the field and 2-for-12 from 3.
The development of that jump shot will be a key. If he shoots better in workouts, teams will be tempted to take him high because of all the elite physical tools.
10. Jakob Poeltl
Previous rank: No. 7
Utah
Sophomore
Center
Poeltl was having a terrific sophomore season before Domantas Sabonis & Co. carved him up in the tournament. Poeltl is big and fluid, rebounds and protects the rim. He also has great hands.
He struggles with physical players, but there's hope that he'll put on the strength necessary to overcome that problem.
11. Deyonta Davis
Previous rank: No. 17
Michigan State
Freshman
Forward
Davis and Ivan Rabb are neck and neck. Who is ahead depends on which team you ask.
They have about the same size and length. Rabb is a bit more advanced offensively. Davis is a more explosive athlete and better shot blocker.
Davis may have the slight edge in upside, especially with the midrange jumper he's developing.
12. Furkan Korkmaz
Previous rank: No. 10
Turkey
Age: 18
Guard
Korkmaz has been getting a few minutes in Euroleague play lately, and on March 25 he posted eight points in 13 minutes for Efes against Unicaja.
He's shooting 44 percent from 3 in Euroleague play and 49 percent in the Turkish league.
That's his major appeal in a draft without a lot of depth at the 2-guard position.
13. Denzel Valentine
Previous rank: No. 24
Michigan State
Senior
Forward/guard
Valentine's season ended prematurely with a first-round loss to Middle Tennessee. But he did his part with 13 points, 12 assists and six rebounds.
The concerns about his pedestrian athleticism seem to be overshadowed by his playmaking and shooting ability.
Is he the wing version of former MSU forward Draymond Green?
14. Domantas Sabonis
Previous rank: No. 23
Gonzaga
Sophomore
Forward
Sabonis was dominant for Gonzaga in the tourney and looks like he may have boosted his draft stock more than anyone else.
He was especially impressive against Utah's Jakob Poeltl, scoring 19 points, grabbing 10 boards and shutting down Poeltl on the offensive end.
He's not a great athlete and he doesn't stretch the floor, but his rebounding, basketball IQ and toughness should allow him to make it in the NBA.
15. Skal Labissiere
Previous rank: No. 13
Kentucky
Freshman
Center/forward
Labissiere is still a mystery to most NBA scouts.
The appeal is clear -- he is big and athletic and can shoot and block shots. But his production at Kentucky was poor, he appeared to lose confidence and he still lacks strength and a great feel for the game.
Most NBA scouts would prefer that he return to Kentucky for another season. But if he doesn't, a team will likely grab Labissiere in the middle of the first round and hope to develop him, given his raw talent.
16. Tyler Ulis
Previous rank: N/A
Kentucky
Sophomore
Guard
Ulis' major leap up our board has less to do with late-season heroics and more to do with the fact that scouts seem to have made peace with his height (5-foot-9).
Ulis does just about everything you'd want from a point guard. He's the best pure point prospect in this draft, and while his size might keep him from becoming a high-level starter in the NBA, he could have a major impact on the right team.
17. Diamond Stone
Previous rank: No. 12
Maryland
Freshman
Center
Stone's old-school game in the paint would've landed him in the top 10 a decade ago.
He's a skilled low-post player, but his lack of elite athleticism and some defensive issues lower his value in the modern NBA.
Any team that drafts him hopes he has some Al Jefferson in him.
18. Timothe Luwawu
Previous rank: No. 16
France
Age: 20
Guard/forward
Luwawu has steadily shined for Mega Vizura all season, averaging nearly 15 points per game and shooting 37 percent from 3.
While those numbers don't necessarily wow you, when you consider Luwawu's defensive potential and athletic profile, he looks like a good 3-and-D player at the next level.
19. Thon Maker
Previous rank: N/A
Australia
Age: 19
Forward
No one's sure exactly where to rank Maker right now.
His decision to declare for the draft took everyone by surprise. If the NBA agrees that he's eligible, a lot will depend on his play at the combine and workouts.
Right now, scouts are all over the place about his value -- ranging from lottery to second round.
We split the difference here at No. 20 given his elite size, motor and emerging skill set. But his lack of strength and feel for the game give scouts pause.
We'll have a much better read on his stock in six weeks, after the combine.
20. Dejounte Murray
Previous rank: No. 28
Washington
Freshman
Guard
Murray had big games in the NIT, putting up 30 points (albeit with seven turnovers) against Long Beach State and 20 points, nine rebounds and five assists versus San Diego State.
He can be wild, but his size, athleticism and toughness -- combined with a real knack for passing the ball -- have scouts very intrigued.
He's got the sort of talent to jump 10 more spots in the draft if he's great in workouts.
21. Ante Zizic
Previous rank: No. 25
Croatia
Age: 19
Center
Zizic's dominance on the boards has been impressive all year. In his last game he collected 12 points and 15 rebounds for Cibona.
His size, athletic ability and rebounding make him a player that a number of teams think could contribute right away.
22. Wade Baldwin IV
Previous rank: No. 15
Vanderbilt
Sophomore
Guard
Baldwin continues to generate significant debate among scouts. His shooting ability and strength are big pluses.
But the surprising losses for Vanderbilt, his lack of explosiveness and his inconsistent play raise issues.
If he went nine or 10 spots earlier in the draft, I wouldn't be shocked. There's a lot of mixed opinion after our top 13.
23. Demetrius Jackson
Previous rank: No. 19
Notre Dame
Junior
Guard
Jackson finished his career at Notre Dame with a 26-point outing against UNC in the Elite Eight.
His explosiveness, shooting, penetration skills and ballhandling were all on display.
A shooting slump this season hurt his stock, but he's one of the few guards in this draft with the sort of elite physical tools to thrive at the next level.
24. DeAndre Bembry
Previous rank: N/A
St. Joseph's
Junior
Guard/forward
Bembry is one of my sleepers for the draft. He is athletic, passes the ball like a point guard and finished the season with some of his strongest games of the year.
He's a jump shot away from being a lottery pick. Unfortunately, he shot just 27 percent from beyond the arc this year, which means he's still pretty far away.
25. Jonathan Jeanne
Previous rank: No. 20
France
Age: 18
Center/forward
Jeanne is a draft-and-stash candidate who could go anywhere outside the lottery to a team willing to wait a few years to see him develop.
The upside -- thanks to a freakish 7-foot-6 wingspan -- is clearly there. He's just a major work in progress.
26. Ben Bentil
Previous rank: N/A
Providence
Sophomore
Forward
Bentil is testing the draft waters, and with teammate Kris Dunn heading to the NBA, it's probably good timing. At times Bentil looked more the NBA star than Dunn did.
He can score from everywhere and plays really hard.
His measurements will be key. If he's 6-foot-8 with a 7-foot-2 wingspan, then he's probably too low. If he's shorter, he might be ranked too high.
27. Brice Johnson
Previous rank: N/a
North Carolina
Senior
Forward
It's tough in any draft for seniors to get love, and Johnson, after three so-so years, still needs to convince some scouts he's a better player now.
Teams have always loved his athleticism and how hard he plays, and now he looks like a rebounder and scorer, too.
Besides his age, his lack of strength continues to be his biggest problem.
28. Stephen Zimmerman
Previous rank: N/A
UNLV
Freshman
Center
Zimmerman's appeal is a unique combination of size and skill set. He has a nice jump shot, runs the floor well and can be a skilled passer. He's also proven to be a good rebounder and shot-blocker. He struggled a bit as a freshman, but there's enough upside here to take him in the first round.
29. Cheick Diallo
Previous rank: N/A
Kansas
Freshman
Forward
Diallo didn't have much of an impact on the court for the Jayhawks this year, but scouts still love his athleticism and toughness. He also has one of the best motors in the draft. His offensive skill set is pretty weak, but his ability to defend multiple positions should help him get drafted somewhere in the first round.
30. Malik Beasley
Previous rank: N/A
Florida State
Freshman
Guard
Beasley is more than just a shooter. He's a terrific athlete who finished nearly 70 percent of his shots at the rim last year. There aren't a lot of shooters in this draft, which means Beasley's stock could rise as the draft goes on.
Next five in
