Editor's note (April 13): This Big Board has been updated with the news that Michigan State's Miles Bridges will not enter the 2017 draft.
As the NBA season comes to an end and teams look forward to the lottery, how do the top prospects in the 2017 draft rank?
I spoke with a number of NBA GMs and scouts to compile this updated ranking of the 30 best players.
Here's our first Big Board since the completion of the college season.
Note that this board projects every player who has either officially declared himself for the draft or is still considering the draft. You can check here for our complete list of who is in, who is out and who is on the fence for the 2017 draft.
We'll update this Big Board if any players listed here decide to return to school for another season. The deadline to declare for the draft is April 23.
1. Markelle Fultz

Previous rank: No. 1
Washington
Freshman
Guard
Fultz continues to hold a slight lead over Ball for the No. 1 pick.
Last week,
2. Lonzo Ball

Previous rank: No. 2
UCLA
Freshman
Guard
Fultz might have the edge on Ball, but it's a small one, and Ball's fans are pretty adamant that he holds more upside than Fultz. His ability to make plays for others stands out as his strongest attribute for scouts.
"Put Fultz on the floor with the same UCLA teammates, and I don't think they're nearly as successful," one GM said.
Still, Ball's porous defense causes many who prefer Fultz to wonder whether Ball can have the same impact on both ends of the floor.
3. Josh Jackson

Previous rank: No. 3
Kansas
Freshman
Forward
Every team in the lottery I spoke with had Fultz or Ball No. 1, but several did mention that Jackson is still in the mix.
He's the best two-way player in the draft, competes harder than anyone else and has a versatility that many teams covet.
The big question: Can he keep hitting jumpers at the same clip he did this season? Some scouts remain skeptical.
4. Jayson Tatum

Previous rank: No. 8
Duke
Freshman
Forward
Tatum's late surge up draft boards has also put him in position to be a dark horse for the No. 1 pick. He's widely regarded by scouts as having the most NBA-ready game right now.
He is strong, scores from both the post and on the perimeter and plays with aggression. However, his ceiling is lower than that of the prospects ahead of him.
5. De'Aaron Fox

Previous rank: No. 9
Kentucky
Freshman
Guard
Fox's stellar play in the SEC and NCAA tournaments really helped his draft stock among teams.
While they are still concerned about his jump shot, he has the rest of the package for a point guard, including speed, toughness, court vision, leadership and the ability to finish at the rim.
6. Jonathan Isaac

Previous rank: No. 5
FSU
Freshman
Forward
Isaac didn't put up the numbers the rest of the elite freshmen did, but a number of scouts think that he might have as much upside as anyone on the board.
He needs to get stronger, but his length, athleticism and skill set for a player his size are intriguing. He's the biggest project in the top 10, but the risk might be worth the reward.
7. Malik Monk

Previous rank: No. 6
Kentucky
Freshman
Guard
Monk was often streaky, but when hitting shots he was unstoppable.
For a league that worships the 3 and has gotten away from traditional point guards and 2-guards, he would be a great fit on a team looking to space the floor.
8. Dennis Smith

Previous rank: No. 4
NC State
Freshman
Guard
Smith's draft stock has slipped a little bit lately as teams questioned his effort and attitude when the Wolfpack's season slipped into the abyss.
There's no question he has elite athleticism and finishing ability at the rim. And he can shoot the 3 and pass the ball. I expect he might climb a bit in workouts once the memory of the college season fades.
9. Lauri Markkanen

Previous rank: No. 7
Arizona
Freshman
Forward
Markkanen is a prototypical 4 in the NBA because of his elite shooting ability from 3-point territory. He also has great size and a great frame for a fluid athlete.
Still, scouts worry a bit about toughness and his pedestrian work on the boards.
10. Frank Ntilikina

Previous rank: No. 11
France
Age: 18
Guard
Ntilikina is averaging nearly 6.0 PPG and 1.5 APG for Strasbourg in France this year.
Those numbers might not wow you, but a number of scouts think his feel, competitiveness and versatile skill set should put him in the mix with Fox and Smith.
11. Zach Collins

Previous rank: No. 14
Gonzaga
Freshman
Center
Collins quietly put together one of the best freshman seasons in college basketball. That he did it coming off the bench at Gonzaga kept him under the radar for a while, but by mid-February, scouts began to fall in love with him as a potential lottery pick.
His strong play in the NCAA tournament didn't raise his draft stock a lot -- he was ranked No. 13 before the tournament and No. 12 after it on our Big Board -- but it did solidify his placement.
12. Harry Giles

Previous rank: No. 13
Duke
Freshman
Forward
Teams still aren't sure where to put Giles. Once their doctors get a look at his medicals, we'll have a clearer picture.
If they think he's healthy, he'll be a likely lottery pick. Many scouts still believe he's one of the best two or three prospects in the draft.
If the medical reports are sketchy, he could slide into the mid-to-late first round.
13. OG Anunoby

Previous rank: No. 21
Indiana
Sophomore
Forward
Anunoby has all the physical tools NBA scouts are looking for in an NBA wing. He's long and athletic, he guards multiple positions and he stretches the floor.
His ACL tear in January means he might miss his rookie season in the NBA; teams will know more when they get to see the medicals in Chicago at the combine. Still, given the major drop-off at this point in the draft, he should be an attractive prospect based on upside alone.
As long as team doctors are happy with his progress, he should go somewhere in the top 20.
14. Jarrett Allen

Previous rank: No. 16
Texas
Freshman
Center
Allen is a raw prospect, but his combination of length, athleticism and impact on the defensive end of the floor makes him appealing.
His offense is still coming along but showed promise as well. He'll compete with Collins and Patton to be the first big man off the board.
15. Justin Patton

Previous rank: No. 15
Creighton
Freshman
Center
Patton is another upside pick in a draft short on big-time center prospects.
He, too, has a way to go to reach his ceiling, but his size and efficiency in the post are both really attractive to teams looking for bigs.
16. TJ Leaf

Previous rank: No. 17
UCLA
Freshman
Forward
Leaf is one of the most skilled forwards in the draft. He can score from everywhere on the floor, rebounds and shows toughness. And his basketball IQ is really high.
Teams worry a bit about his lack of size (6-foot-9). While he's a good athlete, he sometimes struggles to score over length.
17. Luke Kennard

Previous rank: N/A
Duke
Sophomore
Guard
Kennard is testing the waters, but it seems likely that he'll keep his name in the draft.
He is the highest riser on our draft board, despite the fact he really struggled in the NCAA tournament, shooting just 4-for-18 from the field.
Teams are in desperate need of elite shooters, and virtually every scout I spoke with in Portland said they had him in their top 20, and a few had him in the lottery. His toughness and ability to run the point make him more valuable than just a sharpshooter.
18. Terrance Ferguson

Previous rank: No. 22
Australia
Age: 19
Guard
Ferguson's shot didn't fall in Australia the way it did last year at the Nike Hoop Summit, but again, teams are looking for athletic wings who can stretch the floor.
Ferguson lacks the poise and production of Kennard, but he's a better athlete. It will be interesting to see which player gets his name called first. I think these two will meet in a lot of workouts.
19. Ike Anigbogu

Previous rank: No. 29
UCLA
Freshman
Center
Anigbogu is testing the draft waters and will have an interesting decision ahead of him. He averaged just 13 MPG for UCLA as a freshman, but his 4.0 RPG and 1.2 BPG in those short minutes speak to his defensive potential. He's very raw offensively, but scouts see lots of potential growth there, too.
It's a little tough to gauge his draft range at the moment. Teams are all over the board with him, but I think he'll be closer to No. 20 than No. 30. However, another year at UCLA could move him into the top 10 in 2018.
20. Edrice Adebayo

Previous rank: No. 25
Kentucky
Freshman
Forward
Adebayo is also testing the waters, and it's unclear which way he should lean. Scouts weren't enamored with his play for much of the season. The NBA body and athleticism are clearly there, but the production, especially on the boards, didn't come until the last month of the season.
If he stays in the draft, he's projected to go in the mid-to-late first round. If he were to return to Kentucky, dominate as a rebounder and show off his perimeter game, he could become a top-10 pick in 2018.
21. John Collins

Previous rank: No. 18
Wake Forest
Sophomore
Forward
Collins' efficiency as a scorer combined with length and athleticism make him a solid choice in the second half of the first round.
None of the scouts I spoke with see a super-high ceiling for him. But his work ethic and physical tools also point to someone who should be able to carve out a long career in the NBA.
22. Tony Bradley

Previous rank: No. 30
UNC
Freshman
Center
Bradley is also testing the draft waters and, like Anigbogu and Adebayo, will have a tough decision to make. He averaged just 15 MPG off the bench for North Carolina but was very productive in that limited role, especially as a rebounder.
If he returns to school, he'll have the starting center position all to himself and could go 10 spots higher next year. But as Cal's Ivan Rabb shows, there's an inherit risk in coming back to school.
23. Ivan Rabb

Previous rank: No. 19
Cal
Sophomore
Forward
Rabb passed on the chance to be a lottery pick to return to Cal for his sophomore season. While he gained strength and experience on the court, he had a hard time impressing scouts, and his stock has slipped about 10 spots.
His rebounding is his strongest attribute right now, but scouts are still trying to figure out what his contribution will be on the offensive end.
24. Moritz Wagner

Previous rank: N/A
Michigan
Sophomore
Forward
Wagner is also testing the waters after a coming-out party against Louisville in the NCAA tournament helped raise his draft stock. The scouts who were on him all along saw a skilled 7-footer who can stretch the floor and rebound. And he's still just 19 years old.
He was up-and-down all season, but there's a lot of upside here. I think he could really rise in workouts and end up staying in the draft.
25. Justin Jackson

Previous rank: N/A
UNC
Junior
Forward
Jackson's improved shooting stroke from 3-point land this season was the main reason for his rise into the first round, and an NCAA championship adds luster.
But he struggled with his shot a bit down the stretch. He went just 15-for-45 from 3 in the tournament, including 0-for-9 in the championship game. Looking at his shooting numbers from his freshman and sophomore seasons gives scouts pause.
26. D.J. Wilson

Previous rank: N/A
Michigan
Junior
Forward
Wilson is testing the waters after a strong junior season. A terrific run in the NCAA tournament showed off his strengths, including shooting and protecting the rim. That he doesn't turn 21 until December helps as well.
His lack of toughness and his inconsistency during the season seem to be his biggest obstacles to cracking the first round.
27. Jawun Evans

Previous rank: N/A
Oklahoma State
Sophomore
Guard
The draft has five terrific point guards at the top, and then there's a pretty big drop-off.
Evans began the season on fire before cooling off a bit in Big 12 play. Nevertheless, Evans ticks a lot of boxes.
He's a scoring guard who can get his shot from anywhere on the floor. His ability to set up the pass with his shot fits the direction the league is going. But his lack of size and elite athleticism limits his ceiling somewhat.
28. Andrew Jones

Previous rank: No. 27
Texas
Freshman
Guard
Jones is an upside pick with great athleticism, an NBA body, length and some basketball skills. But he's still figuring out how to play the game.
Some scouts love him. Some hate him. He's testing the waters, and he could probably go much higher with another year at Texas.
29. Isaiah Hartenstein

Previous rank: No. 20
Germany
Age: 18
Forward
Hartenstein played at the Nike Hoop Summit last week and was perhaps the most impressive international player overall. He has size, he's bouncy and he's really aggressive on both ends of the floor.
His odd jumper and lack of length raised some concerns among scouts. He's clearly not ready for the NBA but might make a nice draft-and-stash prospect.
30. Caleb Swanigan

Previous rank: N/A
Purdue
Sophomore
Forward
Swanigan had a terrific sophomore season. He has length, strength and an inside-outside game that teams are looking for in a forward. He's a great rebounder and has a high basketball IQ as well. His biggest issue is conditioning. He got in great shape as a sophomore, but teams worry that he might not be able to maintain the weight loss.
