Boston Celtics NBA Mock Draft Roundup

Leading up to the 2020 NBA Draft, we will update our Boston Celtics Mock Draft Roundup showing picks for the Boston Celtics from several prominent sites and draft analysts.

The following are picks in recent mock drafts for the Celtics:

NBA Draft Room, Updated: 6/17
17. Saddiq Bey, Villanova
26. Theo Maledon, France
30. Cassius Stanley, Duke

Excellent 3pt shooter with good length and strength. A 3&D prospect who had a break-out sophomore season.

A well built and explosive athlete with a quick first step. Has all the physical tools to excel in the NBA including nice length and great size/strength at the PG position.

Stanley is a gifted athlete with a very bright basketball future. He's not the most creative in the half court but he's great in transition, has world class bounce and can hit the open 3pt shot.

The Rookie Wire, Updated: 6/16
17. Jalen Smith, Maryland
26. Isaiah Stewart, Washington
30. Nico Mannion, Arizona

The Celtics could use more size, and Maryland's Jalen Smith could be an appealing project for the organization. Smith averaged 15.5 points, 10.5 rebounds and 2.4 blocks per game, and his block percentage (8.3%) ranked among the top 10 high-major underclassmen. He was 10-for-12 (83.3%) when rolling to the basket on pick-and-roll sets, per Synergy. Smith was also an impressive 3-point shooter, showcasing potential as an emerging 3-and-D prospect in the frontcourt.

Isaiah Stewart averaged 17.0 points, 8.8 rebounds and 2.1 blocks per game this past season for the Huskies. Almost exactly half of his offensive possessions were post-ups against smaller defenders, which will not translate when considering that the 6-foot-9 Stewart will be undersized for his position in the NBA. However, he showed more range as a shooter when he was in high school and may have been limited by his system at Washington. Much like Boston did by selecting Romeo Langford last season, Stewart can fit as a long-term development project for the Celtics.

Nico Mannion had the second-best assist percentage (31.5%) among all high-major freshmen. But he shot just (26.0%) from 3-point range during his 19 games against top-100 competition. He was only 37.7% from 2-point range in February, raising concerns about his ability to score in the NBA. Mannion, like aforementioned Pac-12 peer Isaiah Stewart, would be a long-term development project for Boston. However, it is easy to imagine him shaping into a solid backup for Kemba Walker sometime in the near future.

College Basketball Talk, Updated: 6/15
17. Patrick Williams, Florida State
26. Isaiah Stewart, Washington
30. Nico Mannion, Arizona

The numbers look fairly pedestrian, admittedly, but putting them in context is important: Williams was coming off the bench for a Florida State team that goes 11 deep and gives everyone pretty equal minutes. No one ever puts up huge numbers in a Leonard Hamilton program. What they do is incubate players that project as role guys in the league. At 6-foot-8, Williams is a terrific athlete and a burgeoning defender and that can protect the rim and guard out on the perimeter when needed. And while the shooting stroke was somewhat inconsistent this past season, the potential is there -- he did shoot 84 percent from three this year.

What you see is what you get with Stewart. He's a tireless rebounder that, at 250 pounds of solid muscle, is ready to compete in the paint against NBA bigs right now. He's a good post scorer that has shown some glimpses of being able to make threes -- the Washington staff will tell you he's lights out in practice. That's the good. The bad is that he is an undersized center at 6-foot-9 that doesn't have the length or explosiveness to be able to protect the rim at the NBA level, and while he'll put in the effort to guard on the perimeter, he has never really shown that ability. Playing in that Washington zone hasn't helped quell those concerns, either. He's tough, he has a motor, he's really good at the things that he does well, but if he's not going to protect the rim or guard on the perimeter, where does he fit in the modern NBA? I also think Stewart is the kind of guy that will be hurt by the fact that there won't be any workouts. He's an impressive interview that could show off his shooting and, at least in theory, prove what he can do defensively.

I'm not sure whether or not Mannion will actually get drafted this high, but I'm willing to rank him this high because of what his floor is in a draft where there are a number of prospects that could end up being total busts. To me, Mannion has the same kind of prospect profile as the likes of Jalen Brunson, or Fred VanVleet, or T.J. McConnell, or Ryan Arcidiacono. He's a guy that, at worst, will spend a decade playing in the NBA as a backup point guard because of his basketball IQ, his ability to makes shots and the fact that he can operate in a pick-and-roll. My concern with drafting him this high is that he doesn't really have an NBA skill. He's a good athlete but not a great athlete, and that isn't helped by the fact that his wingspan is reportedly 6-foot-2.5. He's not great at beating defenders off the dribble in the halfcourt, which is a problem for an NBA point guard. He's a good shooter but he's not a great shooter. He's a high-level passer but he's not Trae Young or Luka Doncic. He tries defensively but he just doesn't have the physical tools to be a lockdown defender. I'm just not sure what he does that truly sets him apart, and the fact that he was the leader of an Arizona team that kept losing games they shouldn't lose is concerning.

CBS Sports - Parrish, Updated: 6/15
17. Theo Melodon, France
26. Xavier Tillman, Michigan State
30. Zeke Nnaji, Arizona

Theo Maledon is a skilled athlete, one who previously became the youngest LNB All-Star in history. He missed time with an injury while playing professionally in France this past season and was mostly underwhelming -- although, in fairness, he played better as things progressed. But the talent that made him an interesting prospect at a young age still exists and is attractive to NBA executives selecting in this range.

Xavier Tillman used his size and strength to be one of the best defensive bigs in the country this season, one who is also comfortable guarding in space or out on the perimeter. The 6-8 forward averaged 13.7 points and 10.3 rebounds while shooting 55.0% from the field ? and he also made 37% of his 3-point attempts inside the Breslin Center, which suggests he should be able to stretch the floor in the NBA and spend many years in the league as a reliable and quality frontcourt presence.

Zeke Nnaji was only a borderline top-40 prospect coming out of high school -- but he emerged as the biggest surprise of Arizona's freshman class. The 6-11 forward was Sean Miller's most productive player, one who averaged a team-high 16.1 points and a team-high 8.6 rebounds. He was a terrific part of an underwhelming team. Going forward, the best-case scenario has Nnaji developing into a power forward who can create space, rather than trying to be a full-time center, because he's not really a rim-protector. We'll see how that goes. But the fast-developing prospect deserves real consideration this deep in the first round.

Cleveland.com - Goul, Updated: 6/15
17. Isaiah Stewart, Washington
26. Tre Jones, Duke
30. Tyler Bey, Colorado

This selection is top-four protected and will likely remain with Boston, regardless of what happens in the final eight games of the regular season. The Celtics currently have a wing-heavy lineup with Jaylen Brown, Gordon Hayward and Jayson Tatum. Stewart could compete for a starting spot at center, which is currently occupied by Enes Kanter (player option after this season) and Daniel Theis.

This is a luxury pick, following Boston's earlier selection. Jones can become Kemba Walker's backup in Boston and play in spurts with him, if the Celtics want to run Walker at the 2 with a small backcourt set.

With a third pick in the third round, Boston would probably be open to trading this selection. Some of the top available players who also could go in the first round include Kansas guard Devon Dotson and Maryland forward Jalen Smith. Bey was the Pac-12 Defensive Player of the Year and more of a power forward in college. He could move to the 3 in the NBA with a promising shooting touch.

CBS Sports - Boone, Updated: 6/11
17. Precious Achiuwa, Memphis
26. Jaden McDaniels, Washington
30. Desmond Bane, TCU

Danny Ainge values versatility and in Precious Achiuwa he could find plenty. The Memphis product should be a productive power forward but could also be a lethal small-ball five in some situations with the way his motor always runs hot. He's a tenacious rebounder, rim-runner and shot-blocker -- a trio of skills Boston could put to use right away.

Boston has shown a willingness to be patient on players it has drafted in the past, which will be necessary for a potential payoff with Jaden McDaniels. He's brimming with potential as a versatile two-way player who can knock down shots and add good size and length, but his decision making as a passer and in his shot selection is still less than ideal. As he fills into his big-but-skinny frame the Celtics could invest in the talent and bank on him figuring it out all out sooner rather than later.

Which NBA team couldn't use a Desmond Bane? He's a lights-out 3-point shooter with a big frame who can handle it a bit and knows how to play his role effectively. Even on a loaded Celtics roster he could step in as a valuable off-the-bench contributor.

SI.com - Woo, Updated: 6/3
17. R.J. Hampton, G, New Zealand Breakers
26. Aleksej Pokusevski, Olympiacos
30. Jalen Smith, Maryland

There's a palpable degree of skepticism around the league surrounding Hampton's year in Australia, with his range now starting in the late lottery and estimably ending somewhere in the 20s. Hampton does have some things going for him--he's big, fast, plays hard and has some secondary playmaking potential. But his lack of ingenuity makes it fairly clear he's not suited to be a full-time point guard in the NBA, and his shooting struggles call into question what type of value he'll have playing away from the ball. Hampton is a project who will benefit from G League time as he figures out what role he'll need to play to succeed moving forward. But there's still enough upside here to take a shot on him, which will be easier for a team with multiple firsts like Boston.

With Gordon Hayward and Enes Kanter even likelier to opt in for next season in an unstable financial climate, the Celtics' entire rotation will likely return. Boston also carried three rookies last season. They probably don't have room to use all three of this year's firsts, barring some reshuffling via trade. But they also have the luxury of not needing to pick an immediate contributor, which opens up a wide range of possibilities. Pokusevski is as far away from being NBA-ready as anyone in the draft, but if his frame fills out appropriately--and that's an if--it's hard not to see him being a value pick in the 20s given how advanced he is from a skill/size perspective already. He's one of the riskier picks in the draft, but at a point where the cost is mitigated, it's going to be worth a shot.

Teams are all over the board on Smith (which, admittedly, is a trend in this draft), but his ability to protect the basket and potential to shoot from distance in the NBA give him an easier selling point than some of the other bigs in the conversation in this range. As Boston continues to play center by committee, they should be in position to add a player to that mix with one of their first-rounders. Smith's stiff movements are concerning and not everyone is sold on his shooting, but the comparison that continues to come up is a poor man's Myles Turner, which isn't a terrible outcome. He could go 5 to 10 spots higher than this, or fall into the second.

Yahoo Sports - Peek, Updated: 5/21
17. Precious Achiuwa, Memphis
26. Kira Lewis Jr., Alabama
30. Udoka Azubuike, Kansas

Achiuwa stepped up in a big way when Wiseman decided to leave the team in December. He is one of the most athletic players in the draft and has a high upside. His shot selection has improved in the one year under Penny Hardaway and Mike Miller shooting nearly 50 percent from the field this season.

Lewis Jr. averaged 22.8 points per game in the last 10 games of the season including three 30-point performances this year. He is a quick guard and a high-volume shooter who took 10 or more shots per game this season. Lewis Jr. can get up and down in transition and once he gets hot, he'll let it fly from all over the court.

Azubuike improved tremendously this year and became a threat in the lane with his strong back-to-the-basket game and his polished pick-and-roll option with Kansas point guard Devon Dotson. Kansas was the No. 1 team in college basketball and Azubuike showed how powerful he is in the paint where he had a season-high eight dunks against Butler.
