Cooper Flagg was a super star basketball player in college, and everyone thought he'd be picked first in the NBA draft.
The Dallas Mavericks won the lottery to get the first pick, even though they only had a tiny chance of winning!
A photo showed Cooper wearing a Mavericks shirt, making people think the draft was fixed for the Mavericks team.
Many fans were angry because the Mavericks traded away their best player, Luka, and now they might get another great player.
