2020 NBA mock draft: New top three prospects, latest intel

Editor's note (May 20): This mock draft has been updated with the latest intel.

Three months have passed since we previously updated our 2020 mock, and quite a bit has changed in the world of high school, college and international basketball.

We got a chance to evaluate all of the top high school seniors competing with one another in practices and games the past few weeks at the Geico Nationals, the McDonald's All-American Game, the Nike Hoop Summit and the Jordan Brand Classic, learning plenty of new intel.

We'll continue to find out more about the 2020 draft class at the NBA Global Camp in Monaco, the Nike Basketball Academy, the CP3 camp and numerous FIBA competitions over the next few months, but here's how we currently see things, with plenty still to be determined 14 months out.

We used the same projected standing from ESPN's Basketball Power Index for the 2019 draft in this 2020 edition. Although the 2020 draft is too far away to reasonably predict the team order, this gives a sense of picks owed and owned.

RJ Hampton | 6-5 | PG | New Zealand Breakers

Update: Hampton has decided to play in the Australian National Basketball League

We've watched Hampton go up against the top players in high school basketball twice over the past few weeks -- first at the USA Basketball mini-camp at the NCAA Final Four, and then again at the opening session of Nike EYBL.

Hampton was arguably the most impressive player we saw at USA Basketball, as he completely dominated the scrimmages there with his improved frame, passing ability and more consistent jumper. Then he went out this past weekend at the Nike EYBL and scored 29 points per game (the leader among players with complete box scores for all games) by getting to the line 49 times in four games. He finished second in PER behind Cade Cunningham, averaging 5 rebounds and 5 assists for good measure.

Hampton now stands over 6-foot-5 in shoes, with a terrific 188-pound frame that will fill out in time and a 6-8 wingspan. He's a smooth and fluid athlete who changes speeds effortlessly, gets low to the ground with his shifty ball-handling skills and sees both sides of the floor from his high vantage point operating out of pick-and-roll. Hampton knocked down seven 3-pointers in Atlanta, many of which came off the dribble, something that wasn't always a strength of his in the past. He needs to continue to add consistency to this part of his game -- he only shot 27 percent from 3 overall -- but the fact that he has excellent shooting mechanics is a good sign. He's also hitting 74 percent of his free throw attempts.

Not always known for his toughness, Hampton impressed by playing hard consistently and not being afraid to put a body on stronger players in the post on switches, including 6-9 power forwards Jaylen Johnson and Jonathan Kuminga. He also played through contact better than he had in the past. Continuing to add bulk to his frame will be a priority moving forward, as will doing a better job of finishing around the basket in the half-court, an area in which he showed impressive creativity and potential at times.

With measurements similar to the likes of Derrick White, D'Angelo Russell and Jrue Holiday -- while possibly still growing -- Hampton has elite potential at the point guard position thanks to his physical tools, court vision, basketball IQ, budding shot-making prowess and defensive versatility. In what is considered a fairly weak guard class, Hampton could very well have the highest upside. NBA decision-makers have barely gotten a live glance at him, as they haven't been allowed to evaluate him in almost any setting he's participated in due to the age limit, which will likely make him a major focal point of their scouting operations wherever he ends up playing this fall. -- Givony

James Wiseman | 7-1 | C | Memphis

Rank: No. 1 (previously No. 3)

Long considered the most physically gifted prospect in the 2019 high school class, Wiseman has finally turned the corner with his energy and effort, looking every bit like the No. 1 overall pick in 2020. For years, the often-subdued Wiseman left much to be desired in terms of consistency and overall impact, tantalizing with his incredible fluidity, ideal basketball frame and budding skills, yet struggling to find an elite skill or two to hang his hat on. But Wiseman has looked like a different player over these past few weeks, competing during McDonald's All-American practices, putting a lid on the rim at Nike Hoop Summit with six blocks in 22 minutes and winning co-MVP of the Jordan Brand Classic in Las Vegas with 22 points, 6 rebounds and 2 blocks in 24 minutes, featuring a variety of eye-popping plays on both ends.

"Really just getting my conditioning up and making sure I have a consistent motor on a daily basis," Wiseman told ESPN of his improvement. "Studying a lot of film on great bigs in this era. Really going out there and just playing hard because usually in the summertime I always used to be patient. I used to not be involved as well, not running the floor that much even though I had the ability to. So really just doing that on a consistent basis."

Although the NBA certainly isn't clamoring for more centers, Wiseman checks most every box that teams are looking for in a franchise big man, starting with his ability to protect the rim. While not a prolific shot-blocker at the FIBA or Nike EYBL level, Wiseman brings a 7-foot-5 wingspan, 9-3 standing reach, agility and steadily improving instincts that should allow him to anchor a defense at the next level. His measurables rival Joel Embiid's at the same age.

"Timing is everything [with shot-blocking]," Wiseman said. "I've been studying a lot of David Robinson highlights. A lot of Hakeem Olajuwon highlights. So really just studying my timing and really just being there, being alert, improving myself awareness and just be active on both ends of the floor."

While he needs to improve his fundamentals and discipline defending ball screens, Wiseman is also more than comfortable stepping out and sliding with point guards on switches. He stonewalled Jaden McDaniels during the Nike Hoop Summit scrimmage and moves with impressive grace for a player his size. His aggressiveness on the defensive glass is underwhelming at times, but he's really rounding out into a defensive weapon (à la Jaren Jackson Jr.).

Offensively, Wiseman has proved he can add value as a rim runner, lob catcher and even an occasional bust-out ball handler, as he's extremely agile and slithery with unique ball skills. In the half court, though, he's still finding himself, often shying away from contact and opting for finesse over physicality. He's not the most instinctual passer at this stage and lives off a lot of step-back, long 2-pointers in search of earning the unicorn tag. But the fact that he even has the footwork to get to those shots is encouraging, along with his touch to step out and make an occasional 3, a right-shoulder jump hook or a goofy-foot finish.

Although Georgia's Anthony Edwards still poses a major threat at the No. 1 spot given his shot creation at a more coveted position, NBA scouts were wowed by Wiseman's tools and upside, and teams will spend no shortage of time in Memphis next season evaluating the 18-year-old hometown kid on his chase toward becoming the No. 1 pick in 2020. -- Schmitz

Anthony Edwards | 6-3 | SG | Georgia

Rank: No. 2 (previously No. 2)

Edwards was up-and-down at times in his two all-star events -- McDonald's and Jordan Brand -- but vividly showed his talent, and he has a real opportunity to be the No. 1 pick in the draft. Edwards came into McDonald's practices noticeably out of shape but had already trimmed down by the time Jordan Brand rolled around, as he has the type of frame that can get heavy in time if he's not careful about his diet and work habits.

Edwards is a prototype for a modern NBA guard prospect with his ideal combination of size, length, body control, explosiveness, shot-making ability and defensive versatility. His ability to play at different speeds in pick-and-roll, his strength to get his own shot rising up off the dribble, and the scoring instincts he displays finishing through contact are exactly what teams are looking for.

With that said, Edwards is still a bit of an unknown commodity, as he reclassified into the 2020 draft late, played off the radar in high school and AAU, and turned down numerous opportunities with USA Basketball. His effort level comes and goes, he can be very streaky with his jump shot, and his decision-making is still at an early stage. NBA teams say Edwards has some convincing to do to show he can be trusted to be such a high draft pick, but that's exactly why the age minimum was implemented, and he's in a perfect situation at Georgia to show he's worthy of a million-dollar investment. -- Givony

Cole Anthony | 6-3 | PG/SG | UNC

Rank: No. 3 (previously No. 6)

MVP of McDonald's and Jordan Brand -- and the leading scorer for the U.S. in a win at the Nike Hoop Summit -- Anthony displayed alpha-dog status in this class, as he dropped 64 points in 74 minutes on 43 shots between the three games. Yet NBA teams continue to express a degree of skepticism regarding how that might translate to higher levels of competition due to his streaky jumper, his reluctance to make others better and his head-down, at-times-ugly style of play.

Nevertheless, it's difficult not to be impressed by Anthony's scoring instincts and ability to manufacture offense out of nothing, as his ability to play at different speeds, make difficult shots off the bounce and seek out contact are coveted qualities in today's NBA. He's willing to put his body on the line defensively, stepping in for charges, and he has a little more ability to find teammates off the bounce in drive-and-dish situations than he gets credit for.

At UNC, we'll get a better sense for how good of an athlete, shooter, defender and facilitator Anthony is, as well as his skills as a teammate and overall winner -- things on which you hear mixed feedback. Still, it's difficult to argue with his standing among his peers in this class considering how dominant he has been in every setting, and others will need to show they have more value as NBA prospects before we can forecast Anthony going any lower than this. -- Givony

Nico Mannion | 6-3 | PG | Arizona

Rank: No. 7 (previously No. 17)

Mannion helped himself as much as any other player in the class with his showings at McDonald's and Hoop Summit, making a strong case as the top PG. According to our database, going back to 1995, Mannion's single-game performance for the World team was the best the event has seen from an international player in Hoop Summit history, breaking Dirk Nowitzki's record in 1998.

Mannion demonstrated an ideal blend of scoring and passing from a modern guard, knocking down deep jumpers while proving capable of getting into the paint and finishing creatively around the rim. He is already extremely advanced operating out of ball screens, changing speeds instinctively and using well-timed bounce passes or lobs while seeing both sides of the floor. He plays with toughness and intelligence, which his teammates respect.

Mannion will need to continue to work on his body and maximize his athleticism to maintain this lofty projection, as he isn't blessed with prototypical physical tools for a NBA point guard with his negative wingspan and 179-pound frame. He struggled at times defensively and can't always get by better defenders one-on-one, things that will be tested more in college. -- Givony

Jaden McDaniels | 6-10 | SF/PF | Uncommitted

Rank: No. 8 (previously No. 1)

It has been a tough month for McDaniels. He struggled through McDonald's All-America week, looking frail and passive, much to the chagrin of NBA scouts given his clout coming into the event.

Left off the Nike Hoop Summit team, the Seattle-born-and-bred McDaniels had a great opportunity to bounce back in Portland, as he suited up for the PDX Generals -- a team of mostly local high school and college players -- to take on USA in a scrimmage in front of what seemed like the entire NBA.

McDaniels again faltered, going at half speed and looking uninspired on both ends of the floor. Struggling to make shots from the perimeter, McDaniels didn't affect the game in other ways, had issues playing through contact and looked far too flat over the course of the game. McDaniels did remind scouts of his talent for stretches at Jordan Brand, playing with far more aggression in the game by attacking off the dribble into floaters, connecting on pullups with touch and showing some fight on the glass and defensively despite his thin frame. It's important not to overreact too much to his struggles, as he's still 6-foot-10 with shooting potential, a strong positional handle, natural scoring instincts and a solid overall feel for the game. He's a bit of a late bloomer as well.

But McDaniels' development and overall motor have certainly stalled, and his college decision is likely going to go a long way toward determining whether he's able to maximize his potential long-term. -- Schmitz

Scottie Lewis | 6-5 | SG | Florida

Rank: No. 9 (previously No. 4)

Lewis had strong showings at McDonald's All-American and Nike Hoop Summit, looking like one of the higher-floor prospects in this group while still having plenty long-term potential. Lewis is arguably the best defender in this class, at his best using his near 7-foot wingspan, quick feet and exceptionally high intensity level to smother opposing ball handlers at the point of attack. Offensively, Lewis showed glimpses of potential with his streaky shot-making and ability to score in the open floor with his long strides and explosive athleticism, but he remains a work in progress on this end.

He loses confidence in his jumper easily, preferring to get to his midrange pullup rather than take open spot-ups, and he plays a frenetic brand of basketball in the half court, leading to quite a few out-of-control decisions. Learning when to slow down and adding more craftiness to his game will be key toward maximizing his potential, as will improving his narrow frame, which hasn't changed that much over the past year. -- Givony

Precious Achiuwa | 6-9 | PF | Uncommitted

Rank: No. 10 (previously unranked)

Coming off a 22-point performance (on 20 attempts) in the McDonald's game, Achiuwa strung together an outstanding week of practice in Portland, culminating in a strong 15-point, 11-rebound outing at the Nike Hoop Summit game. After an up-and-down high school senior season with Montverde, Achiuwa seemed to benefit from the added spacing of these settings with more opportunities to showcase his on-ball skill set. Achiuwa displayed impressive upside with his physical profile (6-9, 7-2 wingspan), explosive athleticism, budding shot-making ability and flashes of defensive prowess.

Achiuwa is a hungry scorer who is aggressive attacking the rim in the open floor, pulling up off the dribble, shooting with his feet set and taking difficult shots from inside the arc. His ability to change speeds powerfully, finish above the rim and throw in jumpers is intriguing for a player his size, even if his tunnel-vision decision-making and shot selection still often leave a lot to be desired. Achiuwa also is a playmaker defensively who wows you at times with his versatility switching onto guards and protecting the rim. His feel for the game and overall consistency are still a major work in progress, though, and going to the right school will be paramount for him. Ultimately, his combination of tools and talent are just too tantalizing to not project as a lottery talent now. -- Givony

Tyrese Maxey | 6-3 | SG | Kentucky

Rank: No. 12 (previously No. 21)

Maxey helped himself in a big way over the past month with his shot-making, scoring instincts, touch in the paint, confidence and defensive energy at 6-3 with a strong frame and 6-6 wingspan. While he wasn't overly prolific in the Hoop Summit game or Jordan Brand Classic, his talent has really stood out, as he's an ideal fit in the modern NBA with his ability to shoot off the dribble with range, change speeds to get to floaters and make the necessary reads to eventually become more of a lead guard. Maxey is still wired to score, as he'll fire contested jumpers early in the clock or fail to deliver basic passes in traffic. But he also showed enough instincts and change of pace to suggest he'll be able to play more on the ball down the road.

Inconsistent defensively in the past, Maxey guarded with great energy as well, fighting bigger wings in the post and making an effort to slide with guards on the perimeter. He's not the most traditionally explosive leaper and has to keep his frame in check, but Maxey has three-level scoring potential and quite a bit of value in the modern game. Maxey figures to fit well next to Ashton Hagans at Kentucky and could easily have a Coby White-like rise if given the freedom in Lexington. -- Schmitz

Matthew Hurt | 6-9 | SF/PF | Duke

Rank: No. 13 (previously No. 16)

Hurt had a strong week of practice at the Nike Hoop Summit, as he's arguably the most skilled frontcourt player in his class. He can create his own shot on the perimeter, has terrific footwork and touch inside the arc and possesses deep range on his jumper, looking nearly automatic with his feet set. Hurt is bouncy off two feet, shows some budding instincts defensively and looks like a pretty good passer as well, giving him more versatility than your typical standstill shooter.

His frame is a major work in progress, and he needs to prove his ability as a rebounder and defender of quicker guards. It's easy to project a role for Hurt in the modern NBA game with his ability to score from all over the floor, though, and it will be interesting to see how his body continues to evolve once he arrives on campus at Duke. -- Givony

Josh Green | 6-6 | SG/SF | Arizona

Rank: No. 14 (previously No. 9)

Green was inconsistent on the all-star circuit, scoring 13 points on 17 field goal attempts in 41 minutes at the McDonald's and Hoop Summit games combined. Green told us he was battling an illness in Atlanta and suffered a shoulder injury early in the game in Portland, but he did have some impressive moments in practice, plus an MVP showing at the Geico Nationals in between, helping IMG Academy win its first national championship.

Green has too much going for him from a talent standpoint not to think of him as a one-and-done prospect. He's extremely gifted physically, standing 6-6 with a 6-10 wingspan and impressive athleticism, and he shows enough versatility as a passer, ball handler, shooter and defender to bet on his trajectory. He's a talent in the open floor with his impressive combination of explosiveness and body control, bringing the tools to guard multiple positions as well.

Green's jumper will clearly be his swing skill, an area he's struggled with over the past few weeks. His release is fairly stiff and on the slower side, and he struggles to make shots when closely contested, especially off the dribble. Green's ability to affect the game in other ways on nights when his shot isn't falling will help determine how high he gets picked, and he's walking into a good situation at Arizona alongside AAU teammate Nico Mannion. He should make an immediate impact. -- Givony

Trendon Watford | 6-9 | SF/PF | Uncommitted

Rank: No. 15 (previously unranked)

Watford has emerged as a legitimate one-and-done candidate and potential lottery pick thanks to his tools and two-way versatility as a mismatch combo forward. With a physical profile somewhat similar to Kyle Anderson's (6-8½, 227 pounds, 7-1½ wingspan), Watford's ability to handle like a guard, facilitate on the move, make an open 3 and defend multiple positions make him an extremely intriguing fit in today's game.

He has really improved his defensive motor and is playing a far more unselfish brand of basketball, coming into his own as a shot-creator. More long and fluid than explosive, Watford will need to rely on his shooting to rise, as he has natural touch yet doesn't have the quickest release, bringing the ball up across the left side of his face to get to his release point.

As long as he spends most of his minutes as a mismatch 4 at the college level, expect the 18-year-old Alabama native to stuff the stat sheet and get looks in the lottery. -- Schmitz

Wendell Moore | 6-6 | SF | Duke

Rank: No. 18 (previously No. 23)

One of the youngest players in his high school class, the 17-year-old showed glimpses of his NBA value given his versatility, feel and two-way potential. Moore, who has been in the USA Basketball system since he was 15, passes the eye test physically at 6-6 with a strong 215-pound frame and a near 7-foot wingspan, resembling a young Tyreke Evans with his measurements.

Despite suffering an ankle injury in practice, Moore really helped the USA team sneak past the World squad in the Hoop Summit, posting 13 points, 5 rebounds, 3 assists and 2 steals in 23 minutes, sliding between the 1 and the 3 comfortably on both ends of the floor. Although he lacks a degree of offensive aggression/explosion and has yet to prove himself as a 3-point shooter, Moore really knows how to play. He's comfortable handling in pick-and-roll as a primary facilitator and at least has enough mid-range touch to suggest his flat-footed stroke could become more consistent in time (31 percent from 3-point territory on 583 attempts, according to the game-film tool Krossover).

Moore struggled to follow up on his Portland showing in Vegas, as his inconsistent confidence showed at times. With that said, his game isn't suited for an all-star setting. He's a fill-in-the-gaps prospect who does a little bit of everything on both ends and impacts winning in competitive games, just as he did for the USA U16 and U17 teams, winning two gold medals and going undefeated as a starter.

So long as Moore doesn't blend in against ACC competition as a freshman, he could certainly end up as a top-20 pick in the 2020 draft. -- Schmitz

Patrick Williams | 6-8 | SF/PF | Florida State

Rank: No. 19 (previously unranked)

Williams is looking more and more like a one-and-done candidate in the 3-and-D combo forward mold, now standing 6-8, 215 pounds with a 7-foot wingspan, huge hands and an ideal frame at just 17.

Williams didn't wow with his skill level, as he's still a rigid ball handler, streaky shooter and unpolished decision-maker. But the late-blooming North Carolina native showed his clear value on the defensive end, checking up to four positions, displaying great feet and a competitive streak not every prospect brings in a setting like Jordan Brand. Athletically, he made a few spectacular plays in the scrimmage, exploding off two feet, hammering home dunks and attacking the rim powerfully in a straight line. While his stroke is far from natural, Williams does show enough rotation and touch to suggest he can become an average standstill shooter in time, which is supported by his 39 percent clip on 175 attempts, according to Krossover. Williams is a high-intangibles competitor with tools and age on his side -- exactly the type of prospect NBA teams will want to bet on maximizing his potential. -- Schmitz

Kahlil Whitney | 6-7 | SF/PF | Kentucky

Rank: No. 20 (previously No. 11)

Few prospects struggled through McDonald's week and the Jordan Brand Classic quite like Whitney, as his lack of skill level and feel in the half court was more evident than ever. While he's a physical specimen at 6-7 with a 6-11 wingspan and ideal basketball frame, resembling a young Jason Richardson, he really had issues thinking the game against a set defense. He's a rigid ball handler who plays with his head down too often and lives off contested midrange pullups regularly. Although he may never be asked to generate much offense, he still needs to iron out his shooting stroke, as he's a career 31 percent 3-point shooter (242 attempts) and 57 percent free throw shooter (165 attempts), according to Krossover, which showed with several bad misses in Vegas.

Whitney remains a dynamic open-court athlete and a hard-nosed defender with at least some shooting potential to grow into. Because of that, he's still a one-and-done candidate, but if he plays mostly on the wing in Lexington and is asked to create offense in the half court, Whitney might end up spending more time in the collegiate ranks than originally anticipated. -- Schmitz
