Can't the basketball team draw lots after qualifying?

Depending on what kind of games and different rules, some teams were eliminated after finishing the first place in this group. . . There is a saying of "black eight". Moreover, some competitions are drawn after the group stage, and each round is drawn. . . The first place in the small group may be the first place in another group, which leads to the relative inaccuracy of the ranking of the game (the level of the final is staged in advance, although the two teams are similar, the ranking will be much worse). Generally, there will be no more lottery in regular competitions, which is relatively fair.
