Vanderbilt was selected by the Magic with the 41st pick in the NBA Draft, and was traded to the Nuggets shortly thereafter. He missed Summer League play due to a foot injury suffered in college, and his absence continued through exhibition play and the early part of the season. The Nuggets took a conservative approach with Vanderbilt's recovery, but he was able to make his NBA debut Jan. 25 against the Suns. While he saw only four minutes, Vanderbilt still had a point, three rebounds, a steal and an assist. Shortly after that night, Vanderbilt was sent to the G League and saw four games with the Delaware Blue Coats. Over that span, Vanderbilt averaged 7.3 points and 7.8 rebounds before getting the call back to the NBA. He stayed with the team the rest of the season, averaging 1.4 points and 1.3 rebounds in 16 games. Vanderbilt's then-career high came April 2 against Golden State, when he put up 10 points (4-4 FG) and three rebounds. The Nuggets made the playoffs that season, and Vanderbilt saw action in three of the seven games in the opening-round victory over the Spurs. He did not see the court in Round 2 against Portland, the Nuggets where ultimately eliminated in a seven-game series.
