While there is a pool of talented candidates in the 2023 WNBA Draft, some of the biggest stars of the 2022-23 college basketball seasons are not eligible, including Iowa guard Caitlin Clark and LSU forward Angel Reese — the stars who led their teams to the 2023 NCAA Women's Tournament championship game.

If you're wondering, you're not alone. Even NBA star LeBron James — who was drafted straight out of high school in 2003 — has been confused about the rules.

One-and-done is common for men's college basketball players heading to the NBA, but the rules are different for women trying to turn pro. The NBA has a 19-year-old age limit rule that requires players entering the draft to be one year removed from high school. Paulo Banchero only played one season at Duke and was 19 at the time he became the No 1 overall pick in the 2022 NBA Draft. Chet Holmgren and Jabari Smith, the No. 2 and No. 3 picks, were also 19 years old at the time.
