Zion Williamson has missed the equivalent of 3 full NBA seasons in his career.

48 games in 2019-20 season

11 games in 2020-21 season

82 games in 2021-22 season

53 games in 2022-23 season

12 games in 2023-24 season

40 games in 2024-25 season

Add all that up that’s 246 games which is 3 full NBA seasons (3 x 82).

Also because the Pelicans will miss the playoffs Zion is still the only lottery pick (1-14) from the 2019 draft to have still yet to play in a playoff game.
