The No. 44 overall pick by the Heat in the 2019 NBA Draft, Bol was traded to the Nuggets prior to the season and signed a two-way deal. Though a foot injury limited him to just 15 total regular-season games, Bol -- the son of former NBA shot-blocker extraordinaire Manute Bol -- was able to impress in a limited sample. He started by appearing in eight games for the G League's WIndy City Bulls, averaging 12.0 points, 5.8 rebounds and 2.3 blocks despite playing just 19.2 minutes per game. The Sudanese-born center made his NBA debut on Aug. 1 in the Orlando bubble, when he posted five points and four boards in a loss to the Heat. Bol appeared in seven of the Nuggets' eight seeding games. He averaged 5.7 points, 2.7 rebounds and 0.9 blocks across 12.4 minutes per game in that span. The rookie also showed promising touch as a three-point shooter, nailing four threes in nine attempts during the regular season. On Aug. 6, Bol posted his best performance in that span with nine points alongside five rebounds, a steal and a block against the Lakers. In the season finale, Aug. 14 against Toronto, Bol set a personal best with three blocks to accompany eight points and four rebounds. He went on to make four appearances during the Nuggets' trek to the Western Conference Finals. In Game 3 of the first round versus the Jazz, Bol popped for 11 points in just 8:44 on the court. Because he debuted in the bubble, Bol will retain his rookie eligibility for the 2020-21 campaign.
