Under current collective bargaining agreements and NBA eligibility rules, players must be at least 19 years old and one year removed from high school graduation to enter the NBA draft, making it impossible for a 17-year-old to play in the league today. Historically, when direct-from-high-school drafting was permitted, players like Andrew Bynorg and Jermaine O'Neal were drafted at age 17, but they turned 18 shortly after or before taking the official regular-season hardwood court, meaning no player has ever logged an official in-game minute as a 17-year-old.
