Considered to be an adept ballhander and playmaker as well as a solid defender, the 6-foot-7 Bolmaro is projected to be drafted late in the first round or early in the second.
He spent this past season playing for Barcelona, splitting time between the top club and the second-division team.
Scouts have been impressed with his high basketball IQ and his improved shooting over this past season.
His skills are viewed as being raw, but he has a high ceiling and since he will not turn 20 until September, an NBA team could draft him and send him to the G-League as he adds muscle and develops his game.
The campaign was still in its regular-season stage when the coronavirus pandemic forced the league to be suspended in March.
Five teams had already secured play-off places after 28 of the scheduled 34 rounds of games, with three more berths up for grabs.
Anadolu Efes Istanbul sat top of the standings, ahead of Real Madrid and Barcelona, with CSKA Moscow fourth and Maccabi FOX Tel Aviv in fifth place.
However, the EuroLeague Commercial Assets (ECA) executive board declared the season over, announcing the 2020-21 EuroLeague will start on October 1.
It said "every possible option" had been explored before reaching that decision, also announcing the cancellation of the EuroCup campaign.
Given the spread of COVID-19, its degrees of evolution, and the differing ways in which its spread is being controlled within Europe, the ECA said there were "no guarantees" teams would be able to travel to games.
The ECA added in a statement: "In keeping with our continued values of sports integrity and fairness, the executive board decided not to recognise any team as the champion for the 2019-20 EuroLeague, nor the EuroCup."
Euroleague Basketball president and chief executive Jordi Bertomeu said: "Without a doubt, this is the most difficult decision we have had to take in our 20-year history.
"Obviously, we had many motivations to resume the 2019-20 season, but in such an exceptional situation, we have to put people's health first and ahead of any other interest: our players, our coaches, our referees, our clubs, their staff, our league staff, our broadcasters, and all of their families. By doing so, we stay true to our beliefs and what we stand for."
Three referees and a referee coach were being transported to their hotel following Friday's match when the window of their taxi was smashed by two people.
In a statement on Sunday, Euroleague warned it may consider moving future matches from Greece should another similar incident occur in the country.
"Following the conclusion of the Panathinaikos OPAP Athens-FC Barcelona game in Round 25 of the Turkish Airlines EuroLeague regular season in Athens, Greece, two individuals performed a cowardly, criminal attack, smashing a window of the taxi that was transporting the referees from OAKA to their hotel," read Euroleague's statement.
"Fortunately, all three referees, the referee coach and the taxi driver are OK," read the statement. "After the attack, Euroleague Basketball communicated directly with the Hellenic Police, who guaranteed the safety and security of the referees until they departed from Greece."
The statement continued: "Euroleague Basketball and all participating clubs condemn violent acts of any shape or form, and will continue to apply a zero-tolerance policy.
"Euroleague Basketball will support the police investigation into the attack. Should the two individuals be identified, they will be banned for life from attending any Euroleague Basketball game/event, without prejudice to any additional legal proceedings.
"Euroleague Basketball will seek the cooperation of the clubs and the local authorities to prevent any such incidents in the future.
"Whilst the attack is unprecedented in the 20-season history of Euroleague Basketball, should a similar incident occur again within the territory of Greece, this would signify that a safe and secure environment for the visiting teams, referees and all other accredited personnel cannot be guaranteed.
"Therefore, Euroleague Basketball will immediately evaluate relocating all further EuroLeague, EuroCup and U18 Tournament games outside of Greece."
