Jones recorded four double-doubles during the season, including a career-high 26 points to go with 10 rebounds against Chaminade at the Maui Invitational Tournament.

As a result, Jones was deemed ineligible to compete under NCAA rules and was forced to sit out the remaining three games of UNLV's season.

[7] On April 7, 2016, Jones declared for the 2016 NBA draft, but left open the possibility of returning to UNLV or going to another college program by not hiring an agent.

[9] Jones ultimately went undrafted in the 2016 draft, and subsequently joined the Sacramento Kings for the 2016 NBA Summer League.

[17] He went on to make it through to the final round of the Slam Dunk Contest, where he ultimately lost to Glenn Robinson III.

[14] On March 11, 2017, in a 100–98 win over the Dallas Mavericks, Jones made his first start, logging two points, a season-high seven rebounds, and one assist.

[21] On December 12, 2017, Jones was acquired by the Northern Arizona Suns,[22] but did not appear in any games before signing with the Miami Heat later that month.

[23] On a two-way contract, Jones split his playing time between the Heat and their NBA G League affiliate, the Sioux Falls Skyforce.

He made his first start for the Heat on January 9, 2018, in just his third game, recording eight points, five rebounds, one assist and two blocks in 28 minutes against the Toronto Raptors.

[28][29] On August 28, 2021, Jones was acquired, alongside a first and a second round pick, by the Chicago Bulls in a three-team sign-and-trade also involving the Cleveland Cavaliers.

Although initially coming off the bench, he earned a spot in the starting lineup later in the season due to his elite defensive play and impact on the court.

During this run, he primarily guarded the opposing team's best player, including Paul George, Shai Gilgeous-Alexander, and Anthony Edwards.

Jones continued to improve his offensive game as well, showing flashes of increased confidence with his outside shot and becoming a reliable cutter to the basket.
