10 youngest players in NBA history

Allen Einstein // Getty Images When Victor Wembanyama was selected #1 overall in the 2023 NBA draft, he already had success in the French league at the age of 19. His skills and experience make it less surprising that the San Antonio Spurs player is already a star in his first year. His debut performance on the court was so impressive that he was named NBA’s Rookie of the Year in May. However, other young, seemingly promising draft picks have not always fared as well. Before 2006, players could forgo college and be drafted straight out of high school. These young athletes were critiqued more on raw talent than experience, and some of them turned out to be generational stars like Kobe Bryant and LeBron James, but more were unsuccessful in their transition to pro sports. Because of this, the league altered its eligibility rules to state that players must be at least 19 or a year removed from their high school graduation class the year they’re drafted. Though the days of pros straight out of high school are over, ATS.io compiled a ranking of the youngest players in NBA history using Stathead data. The players’ ages when they made their NBA debut were used to determine the ranking. Read on to learn which youngsters thrived, which flopped, and which player made his NBA debut just six days after turning 18. #10. C.J. Miles Lisa Blumenfeld // Getty Images – NBA debut age: 18 years, 241 days – Team: Utah Jazz Before the 2005 draft, C.J. Miles had already signed on to the University of Texas basketball team, his father declaring if C.J. wasn’t drafted in the first round, his son would opt to play college ball. When the Utah Jazz picked him 34th (four picks into the second round), the shooting guard decided he’d forgo college if the franchise guaranteed him a contract (something only first-round picks generally receive). They obliged and signed Miles to a two-year deal. After signing with the Jazz, the Skyline High star became the youngest player in franchise history; however, the move didn’t appear to pan out. During his first season, Miles was assigned to the D-League Albuquerque Thunderbirds, with the Jazz saying he needed more experience. The following season, he played 21 games in the NBA before being reassigned to the D-League team the Idaho Stampede. Although he didn’t live up to the hype of his high school career, Miles ended up playing in the league until 2022 for numerous teams. He last played for the G League team Ignite in 2022. #9. Andris Biedri š Christina Koci Hernandez // Getty Images – NBA debut age: 18 years, 217 days – Team: Golden State Warriors Andris Biedri š was picked 11th overall by the Golden State Warriors in the 2004 draft. The Latvian center didn’t wow during his first season in the Bay Area–he played 30 games and averaged 3.6 points and 3.9 rebounds in 12.8 minutes per game. But those numbers grew, and by the 2007-08 season, he was averaging 10.5 points and 9.8 rebounds per game. In 2007, Biedri š was an integral part of the “We Believe” team that upset the #1 seeded Dallas Mavericks as an #8 seed in the first round of the playoffs before losing to the Utah Jazz in the 2007 NBA Western Conference semifinals. During their improbable playoff run, the big man played 11 games and averaged 6.4 points, 6.3 rebounds and 1.5 blocks. Biedri š ended up playing with the Warriors until 2013. He was traded to the Jazz in the latter part of the 2013-14 season and played six games with them before retiring. #8. Yaroslav Korolev Noah Graham // Getty Images – NBA debut age: 18 years, 181 days – Team: Los Angeles Clippers The Los Angeles Clippers used their #12 pick on Yaroslav Korolev in the 2005 draft, but the perplexing thing is he hardly played in the NBA. Despite only being 18 when he was drafted, the forward had already been playing professional basketball in his native Russia and was on the CSKA Moscow (the top club in Russia) roster in 2004-05. However, he played for the junior team. Korolev played only 127 minutes in his rookie year and even fewer in his second year. He signed a two-year guaranteed contract as a first-round pick but hardly played. He was waived before the start of the 2007-08 season. Although he never lived up to his draft status, Korolev did play in the D-League in 2009-10, then the Euroleague. He officially retired in 2016. #7. Tracy McGrady Craig Jones // Getty Images – NBA debut age: 18 years, 160 days – Team: Toronto Raptors Tracy McGrady was the 9th overall pick in the 1997 draft and came straight out of North Carolina’s Mount Zion Christian Academy. The Toronto Raptors drafted the Floridian and, unfortunately, had trouble adjusting not only to the NBA but the Canadian climate as well. As a result, he only played 53 games in the three years he was in Toronto. Although his time as a Raptor was lackluster, McGrady had a fruitful 16-year career. When he announced his retirement in 2013, the guard had a career average stat line of 19.6 points, 5.6 rebounds, and 4.4 assists. He played with the Orlando Magic, Houston Rockets, New York Knicks, Detroit Pistons, Atlanta Hawks, and San Antonio Spurs. He also made seven All-Star teams between 2001 and 2008 during his time with the Magic and Rockets. #6. Bill Willoughby Keith Torrie // Getty Images – NBA debut age: 18 years, 156 days – Team: Atlanta Hawks When Bill Willoughby was drafted 19th in 1975, he was only the third player to skip college and go straight to the NBA. The forward was a phenom in high school, but unfortunately, his skill didn’t translate well at the pro level. As a result, he was traded often and played for six different teams during his eight-year career. Willoughby later said he regretted foregoing college to go pro and ended up receiving his degree at age 44 (the NBA paid for his schooling). Despite a lackluster career, the New Jerseyan does have a claim to fame: With a 47-inch vertical leap, he was one of the only players who could block Kareem Abdul-Jabbar’s famous skyhook. #5.
