International prospects are the closest thing we have to a mystery in the NBA draft.

For college players, there’s a library of games, a litany of nationally televised appearances, competition of the highest order and intensity. For international prospects, there are often YouTube highlights and a host of questions, the answers to which have gone both ways historically.

Get it right and you end up with a Giannis Antetokounmpo or Luka Doncic. On the other end, there’s Darko Milicic, whom the Pistons took over Carmelo Anthony in a franchise-altering bad decision.

Though the 2019 draft likely won’t be defined by its international prospects, there are still a few who could impact the league in years to come.

The 6-foot-9 Doumbouya rose to prominence playing in France with Limoges and with the international team at the 2016 U18 European Championships. France — led by Doumbouya and Frank Ntilikina — won gold.

Doumbouya projects to be a combo forward and is by far the highest-rated of the international prospects in this draft class. Scouting reports say he’s a strong defender who can switch onto multiple positions and an impact rebounder.

Questions arise with Doumbouya’s offense, though. His assist-to-turnover ratios are consistently poor and he’s shot a career 28-percent from 3-point range. He could go as early as the back end of the lottery.

Bitadze, a 6-foot-11 Georgian, is likely to be the other international player who goes in the first round this year. Bitadze has drawn comparisons to Enes Kanter, another Eastern European big man whose defense is lacking, but their offensive profiles are somewhat different.

Bitadze’s selling point isn’t in the post or as a finisher, but as a stretch big man who can pass the ball on pick-and-rolls. In the EuroLeague this season, he averaged 13.1 points, 6.6 rebounds and 2.9 blocks over 25.3 minutes. Having played in the EuroLeague also mitigates questions about level of competition — it’s a professional league that’s arguably second only to the NBA.

As an NBA big, Bitadze is likely to have the most trouble staying on the floor when opposing teams go small. That will limit his ceiling in the modern NBA, but his shot-blocking ability may help placate some of the negatives.

Samanic is the high ceiling/low floor player of the bunch here, especially after a draft combine performance that impressed.

In a scrimmage in Chicago, Samanic scored 13 points with seven rebounds in less than 20 minutes, on top of testing within the top five at his position in the shuttle run, max vertical leap and three-quarter court sprint.

Keeping in line with the theme, scouting reports describe Samanic’s athleticism as his strength. He can get up and down the court well for a 6-foot-11 big, and finishes well on top of a 33-percent stroke from outside.

However, consistency seems to be a question, with an ESPN scouting report noting that Samanic’s performance changes drastically from game to game. He’s pegged as an early second-rounder or maybe even a late first-rounder.

Sirvydis’ appeal is fairly straightforward: he can play on the wing and shoot well.

Whoever drafts him will be doing so for that reason. The Lithuanian shot 37 percent from 3-point range last season with Rytas, along with 77 percent from the line and a 59 percent true shooting percentage.

At his price — likely the second round or even out of the draft entirely — you could do worse. Physically, at 6-foot-7 and 193 pounds, there are no red flags, though Sirvydis’ defense remains a question. If Sirvydis proves up to the task though, he could be a serviceable 3-and-D wing in the future.

The MVP of 2018’s FIBA U20 European Championship, the Israeli wing has spent the last four seasons at Maccabi Tel Aviv. The level of competition he’s faced — Tel Aviv plays in the EuroLeague as well as the Israeli League — is one of his selling points, but it seems like it could be an uphill battle for Zoosman to be drafted.

The numbers aren’t there for him. In all competitions, he’s averaged 5.2 points, 2.7 rebounds and 1.3 assists in just under 20 minutes. His shooting numbers are middling and scouting reports note he doesn’t score in a diverse fashion.

On the other side, Zoosman’s playmaking is a noted strength, despite the lack of assists. He’s said to have strong vision and feel for the game, attributes that could translate if an NBA team rolls the dice. Right now though, that seems to be a fairly big if.
