Billy Preston

On February 8, 2019, Preston was traded to the Texas Legends for the returning rights of Codi Miller-McIntyre. After just over a month into the 2019–20 NBA G League season, Preston left for the National Basketball League of Australia.

On December 9, 2019, Preston signed with the Illawarra Hawks of the Australian National Basketball League (NBL). He was released after only three games.

On January 20, 2018, Preston signed with Igokea Laktaši of the ABA League and Bosnian League. He made his professional debut 9 days later, recording 2 points, 2 assists, 1 rebound, and 1 steal in 6 minutes of play in a win against Zadar. On March 4, 2018, after playing in only three ABA League games with Igokea, Preston left Igokea due to a sore shoulder that's persistently hurt him during the last two weeks. His name would officially pop up as one of a record-high 236 underclassmen to declare entry for the 2018 NBA Draft on April 24, 2018. Ten days later, Preston was announced as one of a record-high 69 invites for the NBA Draft Combine that year.

Ultimately, Preston went undrafted that year. However, he signed with the Cleveland Cavaliers on June 23, 2018 as a member of their 2018 NBA Summer League team. On July 7, Preston signed a two-way contract with the Cavaliers, meaning he would split his playing time between them and their NBA G League affiliate, the Canton Charge, for the 2018–19 season, with the contract also going into the 2019-2020 season. On December 2, 2018, Preston was waived without appearing in a game for the Cavaliers.

On December 16, 2018, the Erie BayHawks of the NBA G League announced that they had acquired Preston from Canton Charge for the returning right of Jordan Mathews. On February 8, 2019, Preston was traded to the Texas Legends.

Following high school, Preston enrolled at the University of Kansas and had signed to play basketball for the Jayhawks. In November 2017, he was involved in an on-campus car accident that resulted in no injuries. Preston, without having played any games, was sidelined until the completion of a university investigation into the incident. After being barred for over two months, he opted to play at the professional level instead.

Preston played in the 2017 McDonald's All-American Boys Game, scoring ten points and grabbing three rebounds. In the 2017 Jordan Brand Classic, he tallied seven points in 15 minutes of play.

Preston was held out of the Kansas Jayhawks lineup indefinitely due to a car accident on KU campus on November 8, 2017. The accident, which resulted in no personal injuries, triggered an NCAA investigation into the “financial picture” of the vehicle. On January 20, 2018, Preston left Kansas in the middle of the 2017–18 season due to frustration over the investigation. Although he played in Jayhawks exhibition games before the accident, he played no regular-season games for the team.

A Santa Ana, California native, Preston attended St. John Bosco High School in Bellflower, California and Redondo Union High School in Redondo Beach, California, followed by a stint at Prime Prep in Dallas, Texas. In 2016, he transferred to Oak Hill Academy. He had per-game averages of 15.3 points and 9.2 rebounds as a senior at Oak Hill.

In November 2016, he committed to Kansas, after he had also visited Syracuse, Indiana and the University of Southern California during the recruiting process.
